  • Search a variable for an address

    - by chrissygormley
    Hello, I am trying to match information stored in a variable. I have a list of uuid's and ip addresses beside them. The code I have is: r = re.compile(r'urn:uuid:5EEF382F-JSQ9-3c45-D5E0-K15X8M8K76') m = r.match(str(serv)) if m1: print'Found' The string serv contains is: urn:uuid:7FDS890A-KD9E-3h53-G7E8-BHJSD6789D:[u'http://10.10.10.20:12365/7FDS890A-KD9E-3h53-G7E8-BHJSD6789D/'] --------------------------------------------- urn:uuid:5EEF382F-JSQ9-3c45-D5E0-K15X8M8K76:[u'http://10.10.10.10:42365'] --------------------------------------------- urn:uuid:8DSGF89S-FS90-5c87-K3DF-SDFU890US9:[u'http://10.10.10.40:5234'] --------------------------------------------- So basically I am wanting to find the uuid string and find out what it's address is and store it as a variable. So far I have just tried to get it to match the string to no avail. Can anyone point out a solution to this. Thanks

  • How to add new partition to RAID-1 array on Redhat FC10?

  • Chainload boot of Ubuntu installed on 32GB SD card from legacy Grub boot on USB

    - by Gary Darsey
    I have Ubuntu installed on a 32 GB SD card (in the Storage Expansion slot on an Acer Aspire One) with Grub2 installed in the same partition. I boot into legacy Grub on a USB drive and would like to boot by chainloading Grub2 from Grub (kernel/initrd or symlink booting would also be fine), but I haven't figured out how to do this from legacy Grub CLI. Output from blkid for this partition is /dev/mmcblk0p1: LABEL="Ubuntu" UUID="7ceb9fa7-238c-4c5d-bb8e-2c655652ddec" TYPE='ext4" / fdisk -lu information Boot indicator ID 83. Related entries in grub.cfg: search --no-floppy --fs-uuid --set-root 7ceb9fa7-238c-4c5d-bb8e-2c655652ddec linux /boot/vmlinuz-3.5.0-17-generic root=UUID=7ceb9fa7-238c-4c5d-bb8e-2c655652ddec... initrd /boot/initrd.img-3.5.0-17-generic I can't seem to replicate this in legacy Grub. Is there any way get Grub2 to chainload? How do I set root with UUID in legacy Grub? I prefer to boot from USB. Would Grub2 on USB (copying the grub.cfg generated during installation) be an option?

  • What is vt.handoff=7 parameter in grub.cfg

  • NTFS partitions mount as root instead of user as set in /etc/fstab

    - by G1bs0n
    I recently upgraded a server to Ubuntu 12.04 with a fresh install and my NTFS partitions won't mount as user at boot but I can mount them as user manually from the console with $ sudo mount -a. Using ntfsfix reports no problems and chkdisk sees nothing wrong under Windows 7. Are the drives not ready to be mounted at boot and default to root instead of user for some reason? Here is my /etc/fstab: UUID=E4E6B30CE6B2DDCC /media/Bowles ntfs-3g defaults,uid=1000,gid=1000,umask=022 0 0 UUID=A040C42340C3FDD2 /media/Burroughs ntfs-3g defaults,uid=1000,gid=1000,umask=022 0 0 UUID=EA022C73022C46C3 /media/DoctorGonzo ntfs-3g defaults,uid=1000,gid=1000,umask=022 0 0 UUID=BA425A384259FA19 /media/Geist ntfs-3g defaults,uid=1000,gid=1000,umask=022 0 0 UUID=E87CFAE57CFAAE06 /media/DouglasAdams ntfs-3g defaults,uid=1000,gid=1000,umask=022 0 0 Here is the output of ls -l after boot: drwxr-xr-x 1 xbmc xbmc 4096 Oct 31 21:46 Bowles drwxrwxr-x 1 root users 8192 Oct 31 21:46 Burroughs drwxrwxr-x 1 root users 4096 Oct 28 21:45 DoctorGonzo drwxrwxr-x 1 root users 12288 Oct 31 19:56 DouglasAdams drwxrwxr-x 1 root users 4096 Nov 3 01:03 Geist If I unmount and mount again with $ sudo mount -a from console, the output of ls -l: drwxr-xr-x 1 xbmc xbmc 4096 Oct 31 21:46 Bowles drwxr-xr-x 1 xbmc xbmc 8192 Oct 31 21:46 Burroughs drwxr-xr-x 1 xbmc xbmc 4096 Oct 28 21:45 DoctorGonzo drwxr-xr-x 1 xbmc xbmc 12288 Oct 31 19:56 DouglasAdams drwxr-xr-x 1 xbmc xbmc 4096 Nov 3 01:03 Geist Update I was fooling myself, I had a custom udev rule set up to auto-mount file systems by label for USB drives, borrowed from here, but didn't update the rule to accommodate for my additional hard drives. Updating the rule to auto-mount only drives after /dev/sde solved my problem. Thank you again for your reply cartoonist.

  • How to rebuild fstab automatically

    - by yvoyer
    I accidentally removed all the entries from the fstab files while doing a backup (Yeah, I know ;)). I would like to know if there is a way to rebuild it with the current mount options, since I did not restart the server since the deletion.

  • USB Device first mounted as root, then by user

    - by Petr Marek
    When I connect my Kindle, it shows up as an usb0 media, which I can read but not write (owner = root). However, if I do sudo umount /media/usb0, usb0 gets unmounted and a Kindle media gets mounted properly (is writable etc.). What can cause such strange behavior? It's not only with Kindle, but with Flash drives etc. as well.

  • Ubuntu 12.04 Automounting ntfs partition

    - by kuzyt
    Ive looked everywhere to fix this problem but I cant seem to figure out why its doing this. I have the following /etc/fstab entry to mount a ntfs partition using ntfs-3g. UUID=01CD842715EC2180 /media/mediahd02 ntfs defaults,user,noexec,uid=1000,gid=1000,dmask=007,fmask=117 0 2 The volume label for this partition is "MEDIA02" So I have had no problems with the fstab mounting. The problem however is that it automounts again using MEDIA02 label. I'm not sure automounting is the right term for this as its just an empty directory. Deleting this directory and rebooting is causing it to appear again. So listing /media I see both MEDIA02 & mediahd02 htpc@htpc:~$ cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

  • How can I make an unmounted / unmountable NTFS disk not show up in the nautilus devices area?

    - by Dennis
    I have an idea that my /etc/fstab is a real mish-mash and I don't remember how it got that way, first of all it looks like this UUID=9EB80807B807DD21 /media/Storage ntfs-3g users 0 0 UUID=a60397fd-964a-45b1-ad35-53c8a4bee010 / ext4 defaults 0 1 UUID=1764825d-b8ba-4620-b3b0-e979b6f4f5c4 swap swap sw 0 0 UUID=255DA1E406E29DBC /media/sda2 ntfs-3g defaults 0 0 UUID=2CCCF161CCF1262C /mnt/sda1 ntfs-3g umask=000 0 0 /dev/fd0 /media/floppy0 vfat noauto 0 0 I started with an old XP install on disk /dev/sda that I don't use anymore but didn't want to delete, so I shrunk the XP partition, added a NTFS partition that would be common to both systems (Labeled it "Common" in XP), then installed Lucid on an extended ext4 partition. On this disk of course the ext4 system partition comes up as /, the go between partition auto-mounts on /media/sda1 but shows up in Nautilus as COMMOM, while the XP system disk does not show up in Nautilus, but I can get to it by navigating to /mnt/sda1. A second hard drive (/dev/sdb) that I stuck in was already formatted NTFS with a bunch of stuff and labeled "Storage". It auto-mounts to /media/Storage but another un-mounted disk also shows up in the Nautilus device area called Storage but it can't be mounted (Here and in the "Places" are the only times it appears) I would primarily like this non-existant (or already mounted depending on how you look at it) disk to not show up, but I wouldn't mind an explanation of why one labeled partition auto-mounts to a /media mount point but shows up by label, one does not show up as mounted at all but mounts to a /mnt mount point and is there for navigation, and one is mounted to a directory of the same name as the label. I would love to have some consistancy / direction on what is proper in this circumstance. No doubt I caused this with the fstab but I really don't remember what my rational was if I edited it manually

  • How to set individual NTFS partitions permissions behaviour for each user account?

    - by ryniek
    I have two NTFS partitions (DOWNLOADS for downloaded files and VM for my VirtualBox .vdi file) for which i must have full permissions for my allday use account. They should be also automounting when i login to this account. But i've also set Guest account for guests. For Guest account, i want make VM partition fully disabled and invisible (and thus it mustn't automount) but DOWNLOADS partition should be shared with limited privileges with Guest account. Editing fstab i'm able to share DOWNLOADS partition with Guest on limited privileges but VM can be only set to limited and have disabled automounting - so guest can't mount it but it still can be seen in Nautilus, plus I must always mount it manually when i login to allday account. Is there some trick to make what i want? Here's my fstab config: # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 #Entry for /dev/sda1 : UUID=35e66658-5ee9-40cf-bf56-8204959e3df0 / xfs defaults 01 #Entry for /dev/sda2 : UUID=26c714cf-4236-45e7-9c46-cfcf91a215ae /home xfs defaults 02 #Entry for /dev/sda5 : UUID=1315BCB027C44639 /media/DOWNLOADS ntfs-3g auto,uid=1000,gid=1000,umask=0022,nodev,locale=pl_PL.utf8 0 0 #Entry for /dev/sda6 : UUID=60FF39EB72B72264 /media/VM ntfs noauto,uid=1000,gid=1000,umask=0077,nodev,locale=pl_PL.utf8 0 0 #Entry for /dev/sda7 : UUID=c52411f5-105c-45d1-971f-412f962c350e none swap sw 0 0 /dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0 Thanks

  • Using UUIDs for cheap equals() and hashCode()

    - by Tom McIntyre
    I have an immutable class, TokenList, which consists of a list of Token objects, which are also immutable: @Immutable public final class TokenList { private final List<Token> tokens; public TokenList(List<Token> tokens) { this.tokens = Collections.unmodifiableList(new ArrayList(tokens)); } public List<Token> getTokens() { return tokens; } } I do several operations on these TokenLists that take multiple TokenLists as inputs and return a single TokenList as the output. There can be arbitrarily many TokenLists going in, and each can have arbitrarily many Tokens. These operations are expensive, and there is a good chance that the same operation (ie the same inputs) will be performed multiple times, so I would like to cache the outputs. However, performance is critical, and I am worried about the expense of performing hashCode() and equals() on these objects that may contain arbitrarily many elements (as they are immutable then hashCode could be cached, but equals will still be expensive). This led me to wondering whether I could use a UUID to provide equals() and hashCode() simply and cheaply by making the following updates to TokenList: @Immutable public final class TokenList { private final List<Token> tokens; private final UUID uuid; public TokenList(List<Token> tokens) { this.tokens = Collections.unmodifiableList(new ArrayList(tokens)); this.uuid = UUID.randomUUID(); } public List<Token> getTokens() { return tokens; } public UUID getUuid() { return uuid; } } And something like this to act as a cache key: @Immutable public final class TopicListCacheKey { private final UUID[] uuids; public TopicListCacheKey(TopicList... topicLists) { uuids = new UUID[topicLists.length]; for (int i = 0; i < uuids.length; i++) { uuids[i] = topicLists[i].getUuid(); } } @Override public int hashCode() { return Arrays.hashCode(uuids); } @Override public boolean equals(Object other) { if (other == this) return true; if (other instanceof TopicListCacheKey) return Arrays.equals(uuids, ((TopicListCacheKey) other).uuids); return false; } } I figure that there are 2^128 different UUIDs and I will probably have at most around 1,000,000 TokenList objects active in the application at any time. Given this, and the fact that the UUIDs are used combinatorially in cache keys, it seems that the chances of this producing the wrong result are vanishingly small. Nevertheless, I feel uneasy about going ahead with it as it just feels 'dirty'. Are there any reasons I should not use this system? Will the performance costs of the SecureRandom used by UUID.randomUUID() outweigh the gains (especially since I expect multiple threads to be doing this at the same time)? Are collisions going to be more likely than I think? Basically, is there anything wrong with doing it this way?? Thanks.

  • JAXB: How to avoid repeated namespace definition for xmlns:xsi

    - by sfussenegger
    I have a JAXB setup where I use a @XmlJavaTypeAdapter to replace objects of type Person with objects of type PersonRef that only contains the person's UUID. This works perfectly fine. However, the generated XML redeclares the same namespace (xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance") every time it's used. While this is generally okay, it just doesn't feel right. How can I configure JAXB to declare xmlns:xsi at the very beginning of the document? Can I manually add namespace declarations to the root element? Here's an example of what I want to achive: Current: <person uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a"> <relation type="CHILD"> <to xsi:type="personRef" uuid="56a930c0-5499-467f-8263-c2a9f9ecc5a0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> </relation> <relation type="CHILD"> <to xsi:type="personRef" uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> </relation> <!-- SNIP: some more relations --> </person> Wanted: <person uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <relation type="CHILD"> <to xsi:type="personRef" uuid="56a930c0-5499-467f-8263-c2a9f9ecc5a0"/> </relation> <relation type="CHILD"> <to xsi:type="personRef" uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a"/> </relation> <!-- SNIP: some more relations --> </person>

  • Recover LVM2 volume group after one HDD failed

    - by Bernd
    I had two HDDs, each one containing a LVM partition which formed a volume group. Then I had two LVs, one for my / directory and one for my /home/ directory. Yesterday where I had my / dir failed. I'm trying to recover at least my /home/ dir. What I've done so far: Boot a live system Extract LVM2 metadata from the working HDD using dd Copy metadata to /etc/lvm/backup/vg0 Now I'm trying to do this: pvcreate --restore /etc/lvm/backup/vg0 --uuid "[uuid of my working hdd]" /dev/sdb2 But I always get: Couldn't find device with uuid '[uuid of broken hdd]'. Couldn't find device with uuid '[uuid of working hdd]'. Device /dev/sdb2 not found (or ignored by filtering). I confirmed that /dev/sdb2 exists and I've commented out all filtering settings from /etc/lvm/lvm.conf so I don't know what might be causing pvcreate not to find the device. So: What might be the problem? Is it even possible to restore this partition? (As I'm writing this I'm starting to think it's impossible D:) Edit: Okay, looks like I've got it figured out. I was using a Ubuntu 8.10 CD (yeah, I know it's not supported anymore) and it seems that was the problem. When I started from a Ubuntu 10.04 CD everything worked 'fine', I could mount my LVM partitions partially without problems. (Will answer the question in 4 hours. But if anyone has still got some hints/tips, please share! :)

  • XenServer Converting HVM to Paravirtualised

    - by Karl Kloppenborg
    Recently I have been tasked with the daunting process of converting a setup of HVM enabled VMs (running on Citrix XenServer 5.6.0) into PV (paravirtualised) containers. The constraints of the project was that: The operating system must be functionally identical after the migration. minimal modification to the operating system (with exception of kernel / drive mapping) I also was allowed to change the bootloader(ie, grub) in what ever way I see fit. However, I have attempted this, I will firstly like to show you my steps I took. This at the moment is CentOS5.5 specific: Steps: yum install kernel-xen This installed: 2.6.18-194.32.1.el5xen edited: /boot/grub/menu.lst changed my specs to match: title CentOS (2.6.18-194.32.1.el5xen) root (hd0,0) kernel /vmlinuz-2.6.18-194.32.1.el5xen ro root=/dev/VolGroup00/LogVol00 console=xvc0 initrd /initrd-2.6.18-194.32.1.el5xen.img Then I changed my xenserver parameters to match: xe vm-param-set uuid=[vm uuid] PV-bootloader-args="--kernel /vmlinuz-2.6.18-194.32.1.el5xen --ramdisk /initrd-2.6.18-194.32.1.el5xen.img" xe vm-param-set uuid=[vm uuid] HVM-boot-policy="" xe vm-param-set uuid=[vm uuid] PV-bootloader=pygrub xe vbd-param-set uuid==[Virtual Block Device/VBD uuid] bootable=true Some things to note, I am running a VolGroup LVM ;) Anyways, after all these steps (which aren't much!) I boot the VM and it boots initial kernel just fine, however I am presented with this error: Boot Screen: device-mapper: dm-raid45: initialized v0.2594l Waiting for driver initialization. Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes. This may take a while... Activating logical volumes Volume group "VolGroup00" not found Creating root device. Mounting root filesystem. mount: could not find filesystem '/dev/root' Setting up other filesystems.

However in PV mode, this presents itself as /dev/xvda... Could this be the answer? and if so, how the heck to I implement it?? Update: So I have gotten a bit further in my quest, as it now detects the LVM's... To do this, I required to recompile the xen-kernel initrd image. Command: mkinitrd -v --builtin=xen_vbd --preload=xenblk initrd-2.6.18-194.32.1.el5xen.img 2.6.18-194.32.1.el5xen Now when I boot I get this: Boot Screen: Loading dm-raid45.ko module device-mapper: dm-raid45: initialized v0.2594l Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes.

  • straight to grub prompt on boot

    - by cheshirekow
    I am very lost. I did a fresh install of Ubuntu 10.04 on a laptop. First reboot was fine. I ran all the recommended upgrades, and now every time I start I get just a grub>_ prompt. No error message, just the prompt, and a little banner at the top saying grub's version and telling me that I have minimal bash style editing. I've tried: 1) Re-installing grub via sudo grub-install sda (There is only one disk with only two partitions, one primary, and one for swap) 2) Changed GRUB_HIDDEN_TIMEOUT=10 GRUB_TIMEOUT=30 GRUB_CMDLINE_LINUX_DEFAULT="rootdelay=90" GRUB_CMDLINE_LINUX="rootdelay=90" in /etc/default/grub. No luck. I can boot with the following: grub> set root=(hd0,1) grub> probe (hd0,1) -u c00fadde-f7e8-45e7-a4da-0235605f756 grub> linux /boot/vmlinuz-2.6.32-21-generic root=UUID=c00fadde-f7e8-45e7-a4da-0235605f756 rootdelay=90 grub> initrd /boot/initrd.img-2.6.32-21-generic grub> boot And then everything seems to be fine from there. From the grub prompt if I try configfile /boot/grub/grub.cfg The screen clears and I get another grub prompt. So, seriously, what could the problem be? edit: Full text of /boot/grub/grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by /usr/sbin/grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then load_env fi set default="0" if [ ${prev_saved_entry} ]; then set saved_entry=${prev_saved_entry} save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z ${boot_once} ]; then saved_entry=${chosen} save_env saved_entry fi } function recordfail { set recordfail=1 if [ -n ${have_grubenv} ]; then if [ -z ${boot_once} ]; then save_env recordfail; fi; fi } insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=640x480 insmod gfxterm insmod vbe if terminal_output gfxterm ; then true ; else # For backward compatibility with versions of terminal.mod that don't # understand terminal_output terminal gfxterm fi fi insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 set locale_dir=($root)/boot/grub/locale set lang=en insmod gettext if [ ${recordfail} = 1 ]; then set timeout=-1 else set timeout=30 fi ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### set menu_color_normal=white/black set menu_color_highlight=black/light-gray ### END /etc/grub.d/05_debian_theme ### ### BEGIN /etc/grub.d/10_linux ### menuentry 'Ubuntu, with Linux 2.6.32-21-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 linux /boot/vmlinuz-2.6.32-21-generic root=UUID=c00fadde-f7e8-45e7-a4da-0235c605f756 ro rootdelay=90 rootdelay=90 initrd /boot/initrd.img-2.6.32-21-generic } menuentry 'Ubuntu, with Linux 2.6.32-21-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 echo 'Loading Linux 2.6.32-21-generic ...' linux /boot/vmlinuz-2.6.32-21-generic root=UUID=c00fadde-f7e8-45e7-a4da-0235c605f756 ro single rootdelay=90 echo 'Loading initial ramdisk ...' initrd /boot/initrd.img-2.6.32-21-generic } ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/20_memtest86+ ### menuentry "Memory test (memtest86+)" { insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 linux16 /boot/memtest86+.bin } menuentry "Memory test (memtest86+, serial console 115200)" { insmod ext2 set root='(hd0,1)' search --no-floppy --fs-uuid --set c00fadde-f7e8-45e7-a4da-0235c605f756 linux16 /boot/memtest86+.bin console=ttyS0,115200n8 } ### END /etc/grub.d/20_memtest86+ ### ### BEGIN /etc/grub.d/30_os-prober ### if [ ${timeout} != -1 ]; then if sleep --verbose --interruptible 10 ; then set timeout=0 fi fi ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/40_custom ### # This file provides an easy way to add custom menu entries.

  • GRUB-2 Bootloader fails to load for lack of floppy drive. Ubuntu 10.4 & Windows XP

    - by kammer
    2010.07.21 while trying to install Ubuntu 10.4 Hello all, I've been trying to install Ubuntu 10.04 on my Dell workstation and am unable to get the Grub-2 bootloader to load properly. It seems to be failing for lack of a floppy drive on the system resulting in an error message that reads : error: fd0 cannot get C/H/S values. I've gone through the Grub-2 page at https://help.ubuntu.com/community/Grub2 to no avail and other sources having similar problems have likewise turned up no solutions. I would certainly appreciate any insight, here's the background: A while back I was trying to install a different version of Linux and had the same problems, then had to set the project aside for a bit. I don't think this has anything to do with Linux or Ubuntu per se, but rather Grub. The system is an old (4-5 years) Dell workstation that has one drive (128 GB) set up for Windows XP and a second new drive (500GB) which I installed for Linux. There is a DVD/CD drive and the system contains no floppy drive at all. In one attempt to get this working I tried modifying the BIOS to indicate there was a floppy drive - this created a failure earlier in the chain with the BIOS failing to load properly, not unexpected, just a shot in the dark at that point. At the moment I am considering just running out to buy and install a cheap floppy drive to see if that helps. I'll never use the thing though so I'd rather find a solution that doesn't require me to spend money on useless hardware. In any case, here's the /boot/grub/grub.cfg contents: # # DO NOT EDIT THIS FILE # # It is automatically generated by /usr/sbin/grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then load_env fi set default="0" if [ ${prev_saved_entry} ]; then set saved_entry=${prev_saved_entry} save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z ${boot_once} ]; then saved_entry=${chosen} save_env saved_entry fi } function recordfail { set recordfail=1 if [ -n ${have_grubenv} ]; then if [ -z ${boot_once} ]; then save_env recordfail; fi; fi } insmod ext2 set root='(hd1,1)' search --no-floppy --fs-uuid --set fbebde47-f488-41b0-9480-337802ecb988 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=640x480 insmod gfxterm insmod vbe if terminal_output gfxterm ; then true ; else # For backward compatibility with versions of terminal.mod that don't # understand terminal_output terminal gfxterm fi fi insmod ext2 set root='(hd1,1)' search --no-floppy --fs-uuid --set fbebde47-f488-41b0-9480-337802ecb988 set locale_dir=($root)/boot/grub/locale set lang=en insmod gettext if [ ${recordfail} = 1 ]; then set timeout=-1 else set timeout=10 fi insmod play play 480 440 1 ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### set menu_color_normal=white/black set menu_color_highlight=black/light-gray ### END /etc/grub.d/05_debian_theme ### ### BEGIN /etc/grub.d/10_linux ### menuentry 'Ubuntu, with Linux 2.6.32-21-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd1,1)' search --no-floppy --fs-uuid --set fbebde47-f488-41b0-9480-337802ecb988 linux /boot/vmlinuz-2.6.32-21-generic root=UUID=fbebde47-f488-41b0-9480-337802ecb988 ro quiet splash initrd /boot/initrd.img-2.6.32-21-generic } menuentry 'Ubuntu, with Linux 2.6.32-21-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os { recordfail insmod ext2 set root='(hd1,1)' search --no-floppy --fs-uuid --set fbebde47-f488-41b0-9480-337802ecb988 echo 'Loading Linux 2.6.32-21-generic ...' linux /boot/vmlinuz-2.6.32-21-generic root=UUID=fbebde47-f488-41b0-9480-337802ecb988 ro single echo 'Loading initial ramdisk ...' initrd /boot/initrd.img-2.6.32-21-generic } ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/20_memtest86+ ### menuentry "Memory test (memtest86+)" { insmod ext2 set root='(hd1,1)' search --no-floppy --fs-uuid --set fbebde47-f488-41b0-9480-337802ecb988 linux16 /boot/memtest86+.bin } menuentry "Memory test (memtest86+, serial console 115200)" { insmod ext2 set root='(hd1,1)' search --no-floppy --fs-uuid --set fbebde47-f488-41b0-9480-337802ecb988 linux16 /boot/memtest86+.bin console=ttyS0,115200n8 } ### END /etc/grub.d/20_memtest86+ ### ### BEGIN /etc/grub.d/30_os-prober ### menuentry "Microsoft Windows XP Home Edition (on /dev/sda1)" { insmod ntfs set root='(hd0,1)' search --no-floppy --fs-uuid --set 6ef0d4b4f0d4842d drivemap -s (hd0) ${root} chainloader +1 } ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/40_custom ### # This file provides an easy way to add custom menu entries.

  • fd partitions gone from 2 discs, md happy with it and resyncs. How to recover ?

    Hey gurus, need some help badly with this one. I run a server with a 6Tb md raid5 volume built over 7*1Tb disks. I've had to shut down the server lately and when it went back up, 2 out of the 7 disks used for the raid volume had lost its conf : dmesg : [ 10.184167] sda: sda1 sda2 sda3 // System disk [ 10.202072] sdb: sdb1 [ 10.210073] sdc: sdc1 [ 10.222073] sdd: sdd1 [ 10.229330] sde: sde1 [ 10.239449] sdf: sdf1 [ 11.099896] sdg: unknown partition table [ 11.255641] sdh: unknown partition table All 7 disks have same geometry and were configured alike : dmesg : Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x1e7481a5 Device Boot Start End Blocks Id System /dev/sdb1 1 121601 976760001 fd Linux raid autodetect All 7 disks (sdb1, sdc1, sdd1, sde1, sdf1, sdg1, sdh1) were used in a md raid5 xfs volume. When booting, md, which was (obviously) out of sync kicked in and automatically started rebuilding over the 7 disks, including the two "faulty" ones; xfs tried to do some shenanigans as well: dmesg : [ 19.566941] md: md0 stopped.

I tried to reassemble the array but it didnt work: no matter what was in mdadm.conf, it still uses sdg and sdh instead of sdg1 and sdh1. I checked in /dev and I see no sdg1 and and sdh1, shich explains why it wont use it. I just don't know why those partitions are gone from /dev and how to readd those... blkid : /dev/sda1: LABEL="boot" UUID="519790ae-32fe-4c15-a7f6-f1bea8139409" TYPE="ext2" /dev/sda2: TYPE="swap" /dev/sda3: LABEL="root" UUID="91390d23-ed31-4af0-917e-e599457f6155" TYPE="ext3" /dev/sdb1: UUID="2802e68a-dd11-c519-e8af-0d8f4ed72889" TYPE="mdraid" /dev/sdc1: UUID="2802e68a-dd11-c519-e8af-0d8f4ed72889" TYPE="mdraid" /dev/sdd1: UUID="2802e68a-dd11-c519-e8af-0d8f4ed72889" TYPE="mdraid" /dev/sde1: UUID="2802e68a-dd11-c519-e8af-0d8f4ed72889" TYPE="mdraid" /dev/sdf1: UUID="2802e68a-dd11-c519-e8af-0d8f4ed72889" TYPE="mdraid" /dev/sdg: UUID="2802e68a-dd11-c519-e8af-0d8f4ed72889" TYPE="mdraid" /dev/sdh: UUID="2802e68a-dd11-c519-e8af-0d8f4ed72889" TYPE="mdraid" fdisk -l : Disk /dev/sda: 40.0 GB, 40020664320 bytes 255 heads, 63 sectors/track, 4865 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x8c878c87 Device Boot Start End Blocks Id System /dev/sda1 * 1 12 96358+ 83 Linux /dev/sda2 13 134 979965 82 Linux swap / Solaris /dev/sda3 135 4865 38001757+ 83 Linux Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x1e7481a5 Device Boot Start End Blocks Id System /dev/sdb1 1 121601 976760001 fd Linux raid autodetect Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xc9bdc1e9 Device Boot Start End Blocks Id System /dev/sdc1 1 121601 976760001 fd Linux raid autodetect Disk /dev/sdd: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xcc356c30 Device Boot Start End Blocks Id System /dev/sdd1 1 121601 976760001 fd Linux raid autodetect Disk /dev/sde: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xe87f7a3d Device Boot Start End Blocks Id System /dev/sde1 1 121601 976760001 fd Linux raid autodetect Disk /dev/sdf: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xb17a2d22 Device Boot Start End Blocks Id System /dev/sdf1 1 121601 976760001 fd Linux raid autodetect Disk /dev/sdg: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x8f3bce61 Device Boot Start End Blocks Id System /dev/sdg1 1 121601 976760001 fd Linux raid autodetect Disk /dev/sdh: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xa98062ce Device Boot Start End Blocks Id System /dev/sdh1 1 121601 976760001 fd Linux raid autodetect I really dont know what happened nor how to recover from this mess. Needless to say the 5TB or so worth of data sitting on those disks are very valuable to me... Any idea any one? Did anybody ever experienced a similar situation or know how to recover from it ? Can someone help me? I'm really desperate... :x

  • How to pass an xpath into an xquery function declaration

    - by topmulch
    Hi all, I use Apache Tomcat's Exist DB as an XML database and am trying to construct a sequence by passing the following xpath, defined in FLWOR's 'let' clause: $xpath := $root/second/third into a locally defined function declaration, like so: declare function local:someFunction($uuid as xs:string?, $xpath as xs:anyAtomicType?) { let $varOne := $xpath/fourth[@uuid = $uuid]/fifthRight let $varTwo := $xpath/fourth[@uuid = $uuid]/fifthLeft let $combined := ($varOne,$varTwo) return $combined }; Of course, when entering this in the exist xquery sandbox, I get Type: xs:anyAtomicType is not defined. What should I use in place of it, or should I do this a different way? Thanks in advance for any suggestions.

  • Angular function constructor in Controller

    - by BigHeadCreations
    In normal JS I can do this: function Droppable() { this.relevant = true; this.uuid = generateUUID(); }; var generateUUID = function() { return '12345'; } console.log(new Droppable); // returns Droppable {relevant: true, uuid: "12345"} But in Angular I have this: angular.module('myApp').controller('MyCtrl', ['$scope', function($scope) { function Droppable() { this.relevant = true; this.uuid = generateUUID(); } var generateUUID = function() { return '12345'; } // initalize droppable areas $scope.region1 = [new Droppable]; $scope.region2 = [new Droppable]; $scope.region3 = [new Droppable]; }]); I am trying to make 3 droppable areas all with a UUID. But when I do this I get 'undefined is not a function' referring to the line this.uuid = generateUUID(); in function Droppable() {...} Why is that?
