  • Getting an error when mounting LVM snapshot

    - by Sandra
    I have migrated a file based Xen guest to LVM using dd bs=1M if=/dev/zero of=/dev/vg00/vm10 qemu-img convert ~/vm10.qcow2 -O raw /dev/vg00/vm10 and changed the Xen domain file for the VM to use the LV instead of the old file. The VM boots up, and now on the Xen host would I like to make a snapshot of the running VM. # lvcreate --size 10G --snapshot --name vm10-snapshot /dev/vg00/vm10 Logical volume "vm10-snapshot" created # mount /dev/vg00/vm10-snapshot /mnt/snapshot/ mount: you must specify the filesystem type # dmesg |tail EXT3 FS on dm-3, internal journal EXT3-fs: mounted filesystem with ordered data mode. hfs: unable to find HFS+ superblock VFS: Can't find ext3 filesystem on dev dm-4. hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock VFS: Can't find ext3 filesystem on dev dm-2. hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock For some reason it can't see it is an EXT3 filesystem.

  • Windows 7, network connection with no default gateway: any way to change the "Unknown network" statu

    - by e-t172
    Hi, I have a computer running Windows 7 Pro RTM. This computer has two network connections: A Wi-fi connection to the Internet (through a home router) which works just fine. An OpenVPN virtual network connection. More precisely, this is a virtual Ethernet connection which behaves exactly like a physical Ethernet wired connection. My problem is that the "Network and sharing center" shows "Unknown network" for the OpenVPN connection. After some research I found that logical networks (outside a domain) are identified by the MAC address of the default gateway of the connection. Problem is, the OpenVPN connection has no default gateway: it is a private network, so I don't need one... Consequently, the "Unknown network" is always considered public, so the firewall is always in "public mode", which I don't want. Plus, I can't rename "Unknown connection" or anything (which makes sense), so it is kinda ugly. My goal is to define a proper logical network for the OpenVPN connection with the private profile. I know of some workarounds (disable the firewall, modify security policy to make all unknown networks "private") but they're still workarounds. I just want my clients to connect to the VPN without having to disable their firewall settings, without changing global configuration with potential side-effects (the "security policy" solution) and without having to look at an ugly "Unknown connection" in the Network and sharing center. Is there any way I can do this? I tried to check what was going on in the registry (HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList is interesting), but I still didn't find a way to "force" the OpenVPN connection to be assigned to a logical network. Any help would be very appreciated. A related question showed up at Superuser: http://superuser.com/questions/37355/windows-7-cant-identify-network/37422

  • Kerberos service on win2k dc will not start following disk failure

    - by iwilson68
    Hi, I have a win2k (mixed mode domain) with 4 DCS. One of these also acts an exchange 2000 server which uses 2 logical volumes from an MSA 2000 array. AD etc is stored on local drives. We experienced a problem last week when the raid array fell back to a redundant controller and this temporarily meant that the two logical drives were not visible to the server for around 5 minutes and a couple of reboots. The log records these Events as Type: Warning Event Source: Disk Event Category: None Event ID: 51 Date: 06/11/2009 Time: 11:46:23 User: N/A Computer: server1 Description: An error was detected on device \Device\Harddisk1\DR1 during a paging operation. Following these problems, the server “kerberos Key Distribution” service refuses to start with an “error.31 a device attached to the system is not functioning”. All other automatic start services (including net logon) are running and there are no DNS issues etc. All devices are also functioning but the two logical MSA disks are now numbered in the Windows Disk Management MMC as 2 and 4 and I suspect that they may have previously been identified as disks 1 & 2 and perhaps windows still sees this as an ongoing failure?? Replication has not been affected but obviously there are many audit failures in the security log relating to users and workstations presumably linked to the Kerberos issue. Attempting to manually start the kerberos service generates the following in the System Log. Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7023 Date: 09/11/2009 Time: 09:46:55 User: N/A Computer: Server1 Description: The Kerberos Key Distribution Center service terminated with the following error: A device attached to the system is not functioning. DCDIAG passes all tests except “Advertising” and “Services” which I believe relate directly to the failure of Kerberos only. Any advice would be appreciated.

  • Can't mount FAT32 drive under Ubuntu Linux

    - by Josh
    I have a 320GB USB drive with a single large FAT32 partition. The volume mounts perfectly fine on my Mac OS X 10.5.8 machine and Disk Utility on the mac reports no issues with the volume. I can read/write all data on the drive. However when I connect the drive to my Ubuntu 9.10 Karmic system, the partition does not mount. dmesg|tail says: [ 2752.334822] scsi3 : SCSI emulation for USB Mass Storage devices [ 2752.335040] usb-storage: device found at 3 [ 2752.335044] usb-storage: waiting for device to settle before scanning [ 2757.330301] usb-storage: device scan complete [ 2757.331005] scsi 3:0:0:0: Direct-Access WD 3200AAK External 1.65 PQ: 0 ANSI: 0 [ 2757.331772] sd 3:0:0:0: Attached scsi generic sg2 type 0 [ 2757.355647] sd 3:0:0:0: [sdb] 625142448 512-byte logical blocks: (320 GB/298 GiB) [ 2757.360737] sd 3:0:0:0: [sdb] Write Protect is off [ 2757.360749] sd 3:0:0:0: [sdb] Mode Sense: 00 00 00 00 [ 2757.360755] sd 3:0:0:0: [sdb] Assuming drive cache: write through [ 2757.367618] sd 3:0:0:0: [sdb] Assuming drive cache: write through [ 2757.367631] sdb: sdb1 [ 2762.797622] sd 3:0:0:0: [sdb] Assuming drive cache: write through [ 2762.797636] sd 3:0:0:0: [sdb] Attached SCSI disk [ 2822.866228] FAT: bogus number of reserved sectors [ 2822.866237] VFS: Can't find a valid FAT filesystem on dev sdb1.

  • Exchange MSExchangeIS Mailbox Store Error

    - by Bart Silverstrim
    Boss asked me to check to see if I could figure out why he's had to restart the services on the Exchange server three mornings in a row now. While going through the system logs I ran across an error from the MSExchangeIs Mailbox Store, category General, Event 9690. The message said (edited to make generalized): Exchange store 'First Storage Group\Mailbox Store (Servername)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 22GB. This database size has exceeded the size limit of 22 GB. This database will be dismounted immediately. Hmm...happened at five in the morning, and I'm thinking this is a pretty good hint that this leads to the culprit. Thing is I'm not an Exchange expert, so I'm still googling around to figure out how to fix the problem. Any better guidance out there? Or am I barking up the wrong binary tree? Exchange System Manager reports that the server is "version 6.5 build 7638.2, SP2", standard, which I believe is Exchange 2003. It's running on Windows Server 2003 R2 Standard, SP2.

  • Install a KVM guest with LVM partitioning on an LVM partitioned host using virt-install fails, volume group already exists

    - by Rilik84
    our setup consists of a ubuntu 10.04 kvm host server with LVM, on top of which we install the ubuntu 10.04 virtual machines via virt-install and preseed. Each VM has a dedicated logical volume which we pass to virt-install via the "--disk path=/dev/sysvg/vm-name" parameter. The virtual machines themselves are using LVM as well. Virt-install seems to have a few issues with this setup. Say we want to install two virtual machines in parallel. The first vm installs correctly while the second halts during the partitioning, complaining with this error: "volume group name already in use". I tried removing the logical volumes, recreated them, rebooted the kvm host to clear any leftovers but the issue perists. The preseed is telling the vms to create a volume group named "sysvg", which is the same name used by the volume group of the kvm host. Considering this I did another test: I got rid of the preseed part taking care of the partitioning/lvm creation and started the creation of two vms in parallel. If, when prompted, I instruct the vms' installer to do a guided partitioning of the disk with LVM, it will still fail giving this different error on both the vms: Physical Volume /dev/sda5 is already in volume group sysvg. As I wrote, sysvg is the volume group used by the KVM host. So I thought the name clashing was the issue. By removing the preseed part I skipped the volume group naming. I can't understand how the virtual machines would be aware of the presence of that volume group since they're supposed to be isolated from it, especially after I removed and recreated the logical volumes dedicated to them. That detail should not be exposed at all to them! Thanks for the help. I'm clueless.

  • hp proliant dl360 disk diagnostic issue

    - by user1039384
    We recently got two used drives (15000) and installed on our HP proliant dl360 G5 server. Created RAID1 and used HP SmartStart CD to perform diagnostics. Interestingly, the Diagnostic tab immidiately fails on Logical drive testing saying the Disk1 should be replaced, while the Test tab successfully runs all the complete tests on both disks and does not find any issue. At the meantime, when booting to esxi 5, vSphere periodically shows the Disk1 as Unknown and Logical drive in recovery process. This happens every 5-10 minutes. Here is the log from HP SmartScan diagnostic: 1 - Device, Test: Logical Drive 1, Storage Controller in Slot 0 1 - Description: The controller has reported a critical error in the drive error log. 1 - Recommended Repair: This drive should be replaced. 1 - Failed Count: 44 1 - Error code: F157 There is also another error log record (see below): 2 - Device, Test: test_components/libstorage.so ID 2 - Description: An unexpected exception occurred while performing an operation. Exception message: CISS_StatusHandler::evaluate: commandStatus = 4 (INVALID); hexdump of CISS_ErrorInfo: 00000000: __ __ 04 __ 20 __ __ __ __ __ __ __ __ __ __ __ .... ... ........ 00000010: __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ ........ ........ 00000020: __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ ........ ........

If the problem persists, upgrade to the latest version of Insight Diagnostics. 2 - Failed Count: 48 2 - Error Code: F62 Note that rebooting didn't help and I was running the latest diagnostic software version. Anyone has a clue? Is this a real disk issue? BTW, the controller is Smart Array E200i Thanks in advance

  • Getting access to physical drives in ESXi v5.5 installation on Dell PowerEdge R710 with PERC 6/i

    - by Big-Blue
    I've acquired a Dell PowerEdge R710 server a few days ago, which includes a PERC 6/i RAID controller. The server is now fitted with a SATA SSD, one SAS drive and four SATA HDD's, all of which I would like to be passed through to ESXi in an "as-is" state, without creating any logical drives in the RAID controller. Now, the ESXi v5.5 installation image I grabbed from the Dell homepage starts just fine but only lists the logical drives and connected flash drives as possible installation targets, not any of the physical drives. If I create a small logical drive on my SSD (which the PERC 6/i detects as SATA-SSD type), the ESXi install wizard lists the SSD value on that drive as false; which is far from optimal. I have also tried disabling the RAID controller entirely in the setup, but that also did not help. Everything that should enable passthrough is enabled in BIOS, but that shouldn't be a concern at this early stage of the ESXi installation. How would I be able to install ESXi v5.5 to a part of my SSD that is connected to the storage controller, while giving it entire physical access to the disk (to allow for SMART values to be read etc.)?

  • How do I copy files between harddrives on Ubuntu CLI?

    - by ed209
    I have a dedicated server with a 120gb main ssd. The server happens to come with a couple of 3000GB hard drives. I'd like to use them to back up my main drive. Preferably, I'd like one as an exact copy of the main SSD and the other with incremental backups of the mysql database and a user uploads file. These are the drives I have Disk /dev/sda: 120.0 GB, 120034123776 bytes 255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000f2e18 Device Boot Start End Blocks Id System /dev/sda1 2048 4196352 2097152+ 83 Linux /dev/sda2 4198400 5246976 524288+ 83 Linux /dev/sda3 5249024 234441647 114596312 83 Linux Disk /dev/sdb: 3000.6 GB, 3000592982016 bytes 255 heads, 63 sectors/track, 364801 cylinders, total 5860533168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/sdb doesn't contain a valid partition table Disk /dev/sdc: 3000.6 GB, 3000592982016 bytes 255 heads, 63 sectors/track, 364801 cylinders, total 5860533168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/sdc doesn't contain a valid partition table The first problem I have, is that I have no idea how to copy from one drive to another.

(there is nothing under /mnt or /media)

  • Partition is missing in /dev

    - by haimg
    I'm having a strange problem since I moved from Centos5 to Centos6. I have three disks, first two are used as a RAID1, and third one is a stand-alone backup disk that is not listed in /etc/fstab (it is mounded when needed and then unmounted). My problem: After a boot, /dev/sdc exists but /dev/sdc1 does not. Also, the links in /dev/disks are also absent for the first partition of sdc. Disk itself is fine, and if I hot-remove it and plug it back in, /dev/sdc1 appears ok and everything is working. My question: What subsystem manages auto-discovery of disks, partitions, etc. during the boot process (e.g. what creates /dev/disks/by-label)? How do I configure it to scan /dev/sdc too and create all relevant files and links in /dev ? Edit: Here's the relevant part of dmesg output (the only place sdc appears). It does list sdc1, but it's not in /dev! sd 1:0:0:0: [sdb] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 3:0:0:0: [sdc] 976773168 512-byte logical blocks: (500 GB/465 GiB) sd 1:0:0:0: [sdb] Write Protect is off sd 1:0:0:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sd 3:0:0:0: [sdc] Write Protect is off sd 3:0:0:0: [sdc] Mode Sense: 00 3a 00 00 sd 3:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: sdc: sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sda: DMAR:[DMA Read] Request device [00:1e.0] fault addr 361bc000 DMAR:[fault reason 06] PTE Read access is not set sdb1 sdb2 sdb3 sdc1 sda1 sd 1:0:0:0: [sdb] Attached SCSI disk sd 3:0:0:0: [sdc] Attached SCSI disk sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk

  • Extending partition on linux gparted but not more space in the vm

    - by Asken
    I have a vm test installation of a linux running a build server. Unfortunately I just pressed ok when adding the disk and ended up with an 8gb drive to play with. Well into the test the builds are consuming more and more space, of course. The vm drive was resized to 21gb and using gparted I expanded the drive partitions and that all worked fine but when I go back into the console and do df there's still only 8gb available.

    I currently have ubuntu desktop installed on a harddrive. I want to partition the harddrive so that I can reserve 30 gigs for ubuntu server and 30 gigs for ubuntu desktop. The drive has 300 gigs available. Right now I am booting from dvd drive and installing ubuntu server. I selected "Guided partitioning" and created a 30 gig primary partition of Ext4 journaling filesystem, set "yes, format it" for format partition and set bootable flag to on. I intend to use this 30 gig partition to hold ubuntu server and allow me to boot from it. Now I have two other partitions. They are both set to "logical", one is currently using 285.8 gigs and is using ext4 (when I try to set bootable flag to true, it gives a warning "You are trying to set the bootable flag on a logical partition. The bootable flag is only useful on the primary partitions"). More alarming it says "No existing file system was detected in this partition". Actually, Im thinking that this is the parittion that is supposed to be holding my current Ubuntu Desktop. And of course I want this to be bootable and be a primary partition, so I could dual boot from this and the server partition. Now the third partition is also set to logical and it is being used as swap area. My question is regarding that second partition. Its supposed to be a primary partition thats holding my existing ubuntu desktop edition. How do I switch it to primary and to make sure that its pointing to my existing desktop installation?

  • C/C++ line number

    - by Betamoo
    In the sake of debugging purposes, can I get the line number in C/C++ compilers? (standard way or specific ways for certain compilers) e.g if(!Logical) printf("Not logical value at line number %d \n",LineNumber); // How to get LineNumber without writing it by my hand?(dynamic compilation) Thanks

  • Shift Operators in C++

    - by Codeguru
    If the value after the shift operator is greater than the number of bits in the left-hand operand, the result is undefined. If the left-hand operand is unsigned, the right shift is a logical shift so the upper bits will be filled with zeros. If the left-hand operand is signed, the right shift may or may not be a logical shift (that is, the behavior is undefined). Can somebody explain me what the above lines mean??

  • How to delete everything except .svn directories?

    - by Arek
    I have quite complex directory tree. There are many subdirectories, in those subdirectories beside other files and directories are ".svn" directories. Now, under linux I want to delete all files and directories except the .svn directories. I found many solutions about opposite behaviour - deleting all .svn directories in the tree. Can somebody quote me the correct answer for deleting everything except .svn?

  • Messy Filesytem : Duplicate File Removal from the command line

    - by jrause
    In debian/ubuntu I want to a) create a list of all the files in one directory tree b) do the same for a second directory tree c) compare the two lists such that, only the file NAMES are compared (i.e. just comparing the "file.txt" part so that "/home/folder/file.txt" == "/home/secondfolder/folder/file.txt) d) output a list of all the duplicates can anyone please explain how to do this using scripting languages or regex or something?

  • How do I traverse the filesystem looking for a regex match?

    - by editor
    I know this is teeball for veteran sysadmins, but I'm looking to search a directory tree for file contents that match a regex (here, the word "Keyword"). I've gotten that far, but now I'm having trouble ignoring files in a hidden (.svn) file tree. Here's what I'm working with: find . -exec grep "Keyword" '{}' \; -print Reading sites via search I know that I need to negate the name flag, but I can't it working in the right order.

  • How to quickly remove hundreds of thousands of files? [closed]

    - by Nick
    Possible Duplicate: Doing an rm -rf on a massive directory tree takes hours I'm running a simulation program on a computing cluster (Scientific Linux) that generates hundreds of thousands of atomic coordinate files. But I'm having a problem deleting the files because rm -rf never completes and neither does find . -name * | xargs r Isn't there a way to just unlink this directory from the directory tree? The storage unit is used by hundreds of other people, so reformatting is not an option. Thanks
