• Is it possible to boot live USB with latest Kubuntu version 9.10, as is possible with Ubuntu?

  - by CrossHatch

  I see a few guides for Ubuntu on a thumb drive, but will it work for Kubuntu?

• RSync to WebDAV mounted volume very slow

  - by AlexC

  I have a mounted WebDAV store, which I am playing around with to try and put together my own pseudo-DropBox set up. However, it seems very slow to upload larger files (my bandwidth graph goes ok for a little bit, then just stops dead for long periods of time). Has anyone tried this? I'm wondering if the way it gets mounted makes rsync think it's a local drive or something and so may be chattier than it would be if it knew it was a mounted network drive? (I'm new to rsync so may be all wrong here!) I'm syncing using rsync -rv /source/directory/ /mounted/webdav/directory/ This is running using MacOS 10.6, and WebDAV is mounted using the native mounting mechanism.

• fedora liveUSB fails, drops to debug shell

  - by evan

  Trying to install Fedora 15 via a live USB made with unetbootin. I get to the unetbootin boot menu, select Fedora-15-x86_64-Live-Desktop.is, I get to this screen, then it drops into a debug shell with the message sh: can't access tty: job control turned off. The last message is dmseg is dracut Warning: No root device "live:/dev/disk/by-label/Fedora-15-Beta-x86_64-Live-Desktop.is" found. Seems to be the same problem detailed here. Tried to try nk1eto's solution but there is no by-label directory in /dev/disk. There's by-id, by-path and by-uuid.

• How to stop a Linux LVM volume group?

  - by thkala

  I am currently dealing with a multiple disk failure on a Linux LVM Volume Group that is backed up by a RAID-5 md device. One disk has been taken out completely and another one is showing a limited number of corrupt sectors, due to what seems to have been a misbehaving power supply. The problem is that once an I/O error hits, md takes the array down, since it does not have enough devices for it to be operational. Where md the only one involved, I could mdadm --stop the array and then recreate it to get all devices active again. Unfortunately, the array is a PV in an LVM volume group and I cannot seem to get the kernel to release it. vgchange -an does not seem to do anything, bar spew out a couple of I/O errors. I am obviously missing something, but how in the name of -insert-favorite-deity- do I get LVM to release the underlying PV without rebooting the server?

• Apple RAID configuration vs Hardware RAID

  - by James Hill

  I am researching external HDD's capable or RAID 1 to store a large amount of video content during overseas filming. After filming, the content will be brought back to the office and offloaded onto our storage server. After doing some research, I've found that I can buy an external drive with a built in RAID controller, or I can buy an external drive, with 2 HDD's, that I can configure in a RAID 1 array using the OS. RAID 1 is what we're looking for. I've done some reading on software RAID vs. hardware RAID, but the resources I've found don't discuss performance as it relates to video content or what happens to a software RAID when the computer dies. Question 1: Will the hardware RAID be more performant when dealing with large video files? Question 2: If the mac dies, does my RAID die with it (will my data be accessible on another mac)?

• RAID across SAS controller ports

  - by BlueGene

  Hi, I'm managing a HP DL360 G5 machine. It has a SAS controller with two ports. Port 1 is attached to 4 drive bays and Port 2 has 2 bays. The machine currently has 3 drives connected to Port 1 with RAID 5 configuration. I'm trying to max out the bays by adding 1 disk in port 1 and 2 in port 2. Can I group those three disks(1 disk-port, 2 disks-port 2) in a RAID 5 configuration?

• "EISA Configuration" partition

  - by jpbochi

  I have a new Alienware M17x running Vista x64. I just found out that it came with a misterious "EISA Configuration" partition. On Disk Management, my Disk 0 tells me that my HD has about 300 GB. The EISA partition has 12 GB. That's big enough to know why is it there. So, this is more of a bundle question. What is this "EISA Configuration" partition? Is it safe to remove it somehow? If so, how can I delete it? I mean join it with the primary partition, or set it as a secondary small partition.

• What type of malware can reside in windows restore?

  - by qwertymk

  I was reading aking1012's comment on How to create Windows Vista/Windows 7 Startup disk or Rescue disk or system restore points on a CD? . He says that: The first thing I usually do is disable system restore. Some REALLY nasty malware hides in there and is very difficult to delete. As far as rescue media, I make a full backup image. It doesn't directly address the question so it's a comment not an answer, but I thought it was worth noting What type of malware can hide there, and how is that possible as the restore info must be stored with a checksome to make sure it's not modified, right?

• unable to access shared drives n win7

  - by colin

  OK, this is doing my head in. Not your usual Win7 sharing problem. Just built a win 7 comp to go onto my home lan and be accessed by all on the network, mostly running XP SP3. Installed it as a single HD+DVD system, got it happy, then added my storage drives, set them up in the right order and letters, rebooted, and shared them. Couldn't access the computer at all from any XP machine. Set the pasword thingy in win7 to NO, and now I can "see" all four shared drives from any machine, but can access only two of them. Please tell me whats going on as I've done nothing different from one drive to the other, just installed and set up drive letters as normal, then shared the damn things. The odd thing about it? the two 1.5T drives that have a lot of data on board are accessable, the two nearly empty 500G ones are not. ANY ideas? Cheers, Colin

• HDD Carrier, like a soda carrier available at McDonalds?

  - by Jason Taylor

  We use external USB drives for backups, and they have to be stored offsite at the end of the week. Right now we have your standard external USB drive inside an enclosure. We were thinking about moving to a USB dock, and dock a bare HDD for backups, rather than having various sized and types of enclosures. If we were to do this, the drives need protection while being transported to/from the safety deposit box. Is there any kind of hard drive carrier that would let us slide two drives into it, and it would provide protection while the drives are carried around by non-technical people? I'm afraid such a product doesn't exist, but perhaps someone knows of something?

• What are the strategies available to minimise badblocks on an encrypted partition?

  - by David Andreoletti

  Let me explain my backup strategy and the problem I am facing. My current backup strategy: Open encrypted container and execute Carbon Copy Cleaner on it at least once a week. Rotate backup disks. Problem: I have an Truecrypt partition on my 1st external hard disk. I recently found out that some files on this encrypted partition cannot be read due to bad blocks (reported by Antonio Diaz's GNU 'ddrescue'). My backup strategy is ineffective in this scenario because bad blocks are discovered during backup. Possible strategy Strategy #0: Have the encrypted partition over a RAID 1 with 2 disks. Is this a suitable strategy ? Strategy #1: Do you think of any other one ? Environment: Mac OS X 10.8 External 2.5" hard disk (SATA) No RAID

• EC2 persistence of machine

  - by Seagull

  I notice that EBS-backed AMIs are much like a VMWare instances -- I can stop them and also persist them to disk, and all this is done relatively quickly. However, I believe that S3 backed machines are different. They cannot be 'stopped', but rather can only be shut-down, written to S3 disk and started up again; with at least a 15 min delay in doing so. Why the difference? How do AMI providers decide whether to use EBS or S3? If I need to stop/persist/restart machines relatively frequently, then I am implicitly limited to just the EBS-backed machines?

• Computer Studdering When Transferring Over Network

  - by Nalandial

  This is a really weird problem that I've never even seen before. When I copy to or from my server share, my computer studders terribly and the data transfers very slowly at only around 12MB/s. By studdering I mean the mouse skips around and all my applications respond very slowly; as soon as I cancel the transfer it resolves immediately. I looked at Task Manager and the CPU is only at ~35% with plenty of RAM free. This only started semi-recently; before, I had no problems and the transfer speed maxed out the gigabit connection. I have two hard drives in my computer. When I try transferring files between drives it's fine, but when I copy from the share to either drive or to it from either drive, I get studdering. I'm running Windows 7 x64. Anyone have any idea what's going on? Any help would be much appreciated.

  Hi, i have a Dell Poweredge r710 server with five 1 TB disks. All of them are in RAID 5. I was trying to install Centos but it sais "Your boot partition is on disk using GPT Partition...". I read somewhere that centos cant install on 2TB disk, so i made some partiotions smaller, but it's not workin. any idea? p.s. i am going to install Proxmox on that, but Proxmox same doesnt accept 2TB disks...

• MacBook: Can't boot into Linux partition after installation.

  - by Otto

  Hello I just installed Ubuntu. I created a partition in MacOSx using Disk utility, then deleted the partition and installed Ubuntu on the free space created. After the installation, Ubuntu said it would reboot. I hang on shutdown (which is normal, as google told me), so I used the power button to turn the MacBook off. Now I want to boot into Ubuntu. Pressing option/alt on startup only shows me the MacOSx and Windows partition. Also, the Linux partition isn't showing up on my MacOSx desktop. And in Disk Utility, I can see 3 grayed out partitions: "disk0s4", "disk0s5" and "Linux Swap". What can I do to boot into Ubuntu without losing my other partitions? Thank you for your help.

• Non-USB powered laptop cooling pad?

  - by Andrei Rinea

  On my laptop (el-cheapo but pretty good) I have all my 3 USB ports occupied by devices in use (external mouse, external keyboard, 3G internet/flash drive/external hard drive/etc). I want a cooling pad for my hard-worked laptop but all seem to be powered by USB... This laptop is mainly stationary. Either is available a solution to power the USB-powered cooling pad other than connecting it to the laptop... ... either is there a non-USB powered laptop cooling pad?

• Can I mark a folder as mountpoint-only?

  - by Collin

  I have a folder ~/nas which I usually use sshfs to mount a network drive on. Today, I didn't realize the share hadn't been mounted yet, and copied some data into it. It took me a bit to realize that I'd just copied data into my own local drive rather than the network share. Is there some way to mark in the system that this folder is supposed to be a mount point, and to not let anyone copy data into it? I tried the permissions solution here: How to only allow a program to write to a directory if it is mounted?, but if I don't have write access I also can't mount anything to it.

• Sharing external storage between different operating systems?

  - by CT

  I just received a Lacie 1TB external usb/firewire/esata drive. I have 2 machines. A macbook running osx 10.6 and a desktop running windows 7. I would like to rip my dvd collection to iso and store on my external. Right now I use my macbook's disk utility to rip dvds to iso. However my desktop is what is connected to my hdtv. I mainly just use the desktop for media. I'd like to format the external with a 200 GB partition for time machine backups and have the rest for storage. DVD iso are often above 8GB so that sort of eliminates FAT file systems correct? Do I have any options to be able to have my mac and pc both see the drive?

• Removing RAID on a DELL power-edge server

  - by Simon Callan

  We have a Dell Power-edge T110 server, with either a PERC S100 or S300 raid controller (I suspect S100), and 2 x 500GB SATA hard discs. These discs are running in RAID-1 configuration, (either 1 or 2 virtual discs), and on top of this, we have the C and D drives. As we are running low on disc space, we are looking at dropping the RAID to get some disc space back. Is it possible to split the discs back into 2 seperate hards discs that the OS can see, without losing all the data on the drives? Even better, would it be possible to split the D: drive, leaving the OS C: drive in RAID1 configuration?

• How to copy files between windows 7 professional and enterprise machines?

  - by WilliamKF

  I've got a desktop system running Windows 7 Professional and a laptop running windows 7 Enterprise in a domain-joined computer and I need to copy around 50 GB of files from the Enterprise machine to the professional one. I'd rather not burn a bunch of DVDs or use my tiny flash drive of 1 GB to do the transfer. How can I mount a drive from one of the computers to the other so that I can just drag and drop? I tried using a homegroup, but the windows 7 Enterprise laptop does not see it from the professional desktop and the laptop cannot make its own homegroup since it belongs to a domain.

• Which are the most important directories to backup on a Linux server?

  - by QAH

  Hello everyone! I'm running an Ubuntu 9.10 Linux server. I'm trying to find a way to backup the machine while it is running and from what I see, this eliminates the disk clone utilities. All of the disk clone stuff I have seen for Linux requires that you reboot into a special live CD. So my question is this, what is the best solution for backing up the system while it is running? Also, I don't really care about the OS config too much, I just want to be able to keep my stored files and my programs that I have installed on it. Thanks

• Directly paste clipboard image into gmail message

  - by Frank Meulenaar

  I would like to be able to directly paste my clipboard image into a Gmail message. I could then just do alt-print screen, go to Gmail compose and press ctrl-v to embed a screenshot, for instance. I'm not talking about embedding a image from disk into my email; that's easily done. I want to skip the step where I have to save it to disk first. Eudora/Thunderbird support this. There's a program that does this, it's at picturepaste.com, but it's paid (and and the website uses Javascript for no obvious reasons). You can see the demo movie there if it's not clear what I would like. I would like to find a free alternative, or make one myself, but I have no clue how picturepaste works.

• Create 8.3 name for an existing directory

  - by Chris Karcher

  I have a machine that initially had 8.3 filename creation disabled. However, this was causing issues with some legacy software, so it was re-enabled. I'm wondering if it's possible to go back and "add" 8.3 filenames to certain existing directories. For example, say I have a directory named "C:\name with spaces" and I get the following output when I run "dir /x": C:\>dir /x Volume in drive C has no label. Volume Serial Number is 6873-65B8 Directory of C:\ 04/09/2010 01:57 PM <DIR> name with spaces ... I'd like to somehow add an 8.3 name for the directory without recreating it, and then get the following: C:\>dir /x Volume in drive C has no label. Volume Serial Number is 6873-65B8 Directory of C:\ 04/09/2010 01:57 PM <DIR> NAMEWI~1 name with spaces ... I tried the 'rename' command but it didn't do the trick.

• Annoying Search Behavior - Search Companion

  - by David Stein

  I'm running Windows XP Professional, and ever since the last service pack I've had a searching problem. When I want to search a network drive, I get the following message: This folder is not indexed. To search this directory plase use Search Companion or add this directory to your index via options. Basically, I have two questions. Is there some way that I can use the indexed search where appropriate and then have it switch over to the Search Companion automatically? Second, how does a programmer look at this code and think this is a good idea? I realize that this question is rhetorical. However, I must enter my search string into one search, receive the error, and then click "Search Companion" to bring up the new search window. This window doesn't even take the defaults from the previous one so I have to specify the search string and drive again.
