Fedora :: UUID Format Of Drives Changed With New Motherboard?
Mar 11, 2010
I am trying to recover some data on some drives that are in the same LVM. When I upgraded the motherboard, I had complications getting the drives to all load under the LVM, and in the process I made the mistake of formatting one of the drives. The problem now is that the UUID changed on the drive so when I try to mount the LVM it can't find device with a certain UUID. When I try to set the UUID back to the old one it says 'Invalid UUID format'.
I can set it to a UUID generated through 'uuidgen', si I then noticed that the format of that UUID is different than the old one which I'm trying to set it to. Why is that? Is there a way I can get it to change to the old one in the different format?
The old format: yQtrVB-5jCk-vF10-05c2-AcDL-GNn1-ivdxxh
The new format: d5224587-a6cd-4a66-a12b-d7b75eec5871
I am trying to figure out how to get the UUID for some of my external hard drives.the internet revealed a couple of promising leads, this is what I have tried so far:
ls -l /dev/disk/by-uuid -> didn't list the hard discs blkid -> didn't list the hard discs lsusb -v -> listed the hard disc but no uuid
A normally formatted usb key is listed with uuid. The external hard discs are fully encrypted by truecrypt(realcrypt). I have been reading not so great things about that itself, but for now I don't have a promising alternative that I can use with windows as well.Any google searches don't seem to cast any new light on this for me,I'd be open to suggestions if there's a better way to get a definite ID for a hard drive... I just need to be able to mount it with realcrypt
I just went out and bought stuff to build a new computer, and among the parts was a Gigabyte ga-890fxa-ud5 motherboard ([URL]). The board has 3 (well, 4, but we'll stick to the 3) main sata interfaces, with 2 slots per interface, allowing 6 sata drives. In slot_0 i put my blu-ray drive, in slot_1 i put my drive that will host the OS and its partitions, and that is in the sata connector pair on the left. The middle sata connector pair (slot_2 and slot_3) i have 2 2tb drives, and in the sata connector pair on the right (slot_4 and slot_5) i have 2 1.5tb drives.
Someone (not me) recently installed some new distros on my HD. It seems that during the installation my swap partition was reformatted and a new UUID was assigned to it. I have the following questions:
1. I know that I have to change the swap partition UUID in /etc/fstab and /boot/grub/menu.lst of the affected distros. Is there anything else that needs to be changed? 2. I presume a similar change has to be made to the Grub 2 configuration, for those distros that use Grub 2. I have no experience using Grub 2 so how do I make the change or where can I find instructions to do it?
I'm running 64bit Lucid. I've recently had a severe problem with my softraid (5) array, and have had to recreate the array to fix it. However this now means that something is up with GRUB/initramfs, and booting times out while waiting for the root device (md0) to be ready. /boot is on a normal partition, not the raid array itself. A friend of mine has rebuilt my initramfs file with the new UUID, but now I get the message: 'Kernel panic not syncing: VFS: unable to mount root fs on unknown-block (9,0)'.So my question is either how do I sort this error, OR how do I rebuild initramfs/grub in a way that will boot?
I changed my menu.lst to use root=UUID=<long uuid string> instead of the good old root=/dev/sd...
I did that because, if I boot with a usb drive attached to my computer, sda become sdb and therefor nothing works anymore since my friend Kernel can't mount it's root partition. BTW, it works wonders using the UUIDs. The story darkens each time there is a kernel update, dist-upgrade resets my menu.lst back using the /dev/sd... format. and BANG... no more booting again. I am good to change my menu.lst back each time.
I have three Linksys NSLU2s each running nearly identical setups: SlugOSBE 5.3 with two USB SATA hard drives in enclosures. One partition on each drive is used for software RAID 1. The third NSLU2 which has two identical 500gb Western Digital Blue Scorpion SATA drives and two identical USB enclosures (Flexmate) is giving me issues. The second hard drive keeps getting booted from the RAID array - looking into it I noticed that, for some reason, Linux is reading both RAID partitions as having an identical UUID. I thought maybe that was the issue so I've set about trying to fix it.
SlugOSBE doesn't have tune2fs, so I removed the drives and used tune2fs to create new UUIDs for both partitions (which usually show up as /dev/sda3 and /dev/sdb3) on my Kubuntu 10.10 machine. tune2fs reports the correct new UUID under Kubuntu. But when I plug the drives back in to the NSLU2, it still shows the old UUID for both drives. I've deleted /etc/blkid.tab, but that doesn't seem to do anything.
My System Intel Core Duo E5300 Mobo - Gigabyte G31M-ES2L 1GB DDR2 800MHz RAM 4 x WD20EARS HDD I have been trying to install Fedora or Ubuntu for over a week. I thought it would take an hour and i would be away. I have been trying to install using the mdadm Software RAID feature. Everytime it takes about a day to format the drives and then i get an installation error. The drives state they are ready to use as is on any operating system other then WinXP, but this does not appear to be the case.
I am very new to Fedora... I have been doing some reading.[URL].. That information has been promising. I have been able to get into Fdisk off the live CD but i can't figure out how or if it is possible to do what i want it to.
Has anyone had any luck getting these drives to function correctly in a software RAID? I have had good luck with WD drives in the past and just assumed these drives would do what i wanted to but alas i have been proven wrong.
The partitions i wanted was... - A 2GB swap parition - A 10 GB RAID 1 partition for Fedora - The remaining space as a Raid 5 for files.
Am i just banging my head against a wall here, or is this possible.
Is there something special I have to do to get grub to use UUID's? I am putting a couple of extra drives into a 9.10 system (default installation) with a SCSI drive for the OS. That SCSI drive was sda when I built the machine but of course gets bumped when I add these other drives. The fstab file contains UUID's. All attempts to boot with the other drives attached fail.
I am currently thinking about moving my debian install onto another more powerful motherboard/processor/ram amount. My question is how difficult will the move be?
I have done some reading on cloning and or moving. It seems like moving is the best bet,

It looks like its as simple as moving the harddrive. But what about multiple hardrives with LVM set up? I also realize I will probably have to find the network drivers for the new motherboard. There's probably other drivers that will need to be installed as well. What would need to be configured in terms of VM set up?
The former set up is,
Asus MB with i3 and 8GB of ram 3 hard drives VLM set up samba server for the local windows machines Virtual Box with one VM - Win 7 SNTP server set up to serve the home network. SSH with keys VirtualBox PHP Transmission for torrents Plex and Subsonic (for remote streaming), other assorted packages
New Set up is,
Intel mobo with i5 and 16 GB of ram -I would literally be moving the hard drives into this computer
I have an IBM xSeries server with a 120gb IDE hd. I would like to use it for mail and web server at work. Obviously, I need a bigger HD. The only thing is I can't find a big (1TB) IDE HD all I can find are SATAs and this server's motherboard does not support SATA drives.
I am purchasing a Western Digital WD10EARS 1TB hard disk for use with Fedora 11. My questions is will I get good performance or do I need some tweaking?
This drive has the new Advanced Format with 4k physical sectors. Some people have had performance problems with these drives. I want to make sure Fedora 11 can format the drive corectlly.
I just finished a build of a new GNU/Linux boxen with openSUSE 11.2. I have a MSI Big Bang Xpower X58 motherboard which has two SATA controller chips, one is the standard Intel ICH10R chip for SATA 3.0 Gb/s and one is the Marvell 9128 chip for SATA 6.0 Gb/s. The BIOS recognizes the Western Digital Caviar Black 6.0 Gb/s drive on either SATA controller chips, /however/ I am unable to install (and boot) when the drive is connected to the Marvell controlled ports. As you can guess, I'd like to boot from the faster interface!
1. The BIOS allows me to select the Western Digital drive as a secondary boot device, so I know, at least at the BIOS level, it's there. This is true whether I have the drive connected to the Intel or Marvell ports. (The DVD drive is the primary boot device.)
2. When trying to install openSUSE 11.2 from DVD, the installer says that it can't find any hard drives on my system when I have the drive connected to the Marvell port. The installer finds the drive fine when it is connected to the Intel port.
3. I installed everything with the drive connected to the Intel port. I switched the drive to the Marvell port afterward and the system refuses to boot completely, stalling at some point where it starts to look for other filesystem partitions. This led me to conclude that perhaps the problem is with openSUSE and not hardware weirdness with the system having two separate SATA controllers?
Someone in my dept rather stupidly changed an IP of a webserver, and ever since we changed it back we cannot mount 3 NFS drives.
The Error Code: HTTP1:/etc# /etc/init.d/networking restart Reconfiguring network interfaces...if-up.d/mountnfs[eth0]: lock /var/run/network/mountnfs exist, not mounting if-up.d/mountnfs[eth1]: lock /var/run/network/mountnfs exist, not mounting done.
I have removed that lock file and tried a Code: mount -a but it just hangs?
The FSTAB hasn't changed at all, and the other web servers can mount to the NFS share fine. I have tried alot, removing the lock file and rebooting etc but no luck. Debian Lenny.
I have a 1TB hard drive which is formatted with FAT32. Attempting to make a new partition I clicked the format drive button in Disc Utility. I chose Master Boot Record and something was written to the drive. So now I can't mount the drive and Disc Utility says that there aren't any partitions. I don't think this can be true because I had 200 GB of data on the drive and it would have taken longer to delete all that. At least I think...
I have a nice computer i have been dual booting between either ubuntu or win7. i am wanting to remove win7 and install winxp sp3, so i can use media center with my xbox. i preferred that win7 work, but since my copy is not genuine, its authenticity is believed to be the culprit in connection errors with the xbox. i have not been able to find a linux alternative, which i doubt even exists due to the proprietary nature of the xbox.
So, my question is how do i reformat the win7 hard drive? are there issues i need to worry about that may reformat both hard drives on accident? and when the hard drive is formatted, will i be prompted to choose which hard drive to install win xp on?
I am trying to install windows 7 over Ubuntu, however when i run the install disk it tells me that my hard drive is not formatted in the correct format. I have then loaded up Ubuntu, tried to re-format using Gparted and it won't let me re-format my hard drive when I right click on it. The only option I get when right-clicking is to unmount the drive.
how to format flash drives in ubuntu. In windows there was a "format" on the right click menu but I did not find one in ubuntu. i am using ubuntu jaunty.
I have 2 drives mirrored via windows software raid and I plan to toss the drives into an Ubuntu server soon where they will also be mirrored. The server will have another drive for booting. What is the best way to get these mirrored drives into ext format while preserving my data? I plan to use software raid in Ubuntu as well. My only idea is to format a 3rd drive as ext and copy all the files over, seems inefficient though.
The 400GB has the OS and SWAP while the 1TB are going to be used as storage....
Now for the problem, when I have both the 1TB drives in I can not format or mount either 1TB drives. Says Device is in use or "The device file '/dev/sdc1' does not exist"
Now if I take one of the 1TB drives out I can format, partition, and mount it no problem...it only seems to be a problem when both drives are connected...
i need to shred (or at least do a low/high level format) the drives before giving them to my parents (because they know about undelete and stuff). so, what apps can i use in ubuntu to do this?
i have instaled ubuntu 11.04 wubi on my pc with windows 7. i installed and everything was going ok i navigate on ubuntu already. but the problems star here i went on my ubuntu to the partition section and i format my windows partion to be the home partion and changed the nfts to ext, i did the upgrades but i forgot that theyr running yet and i restart my computer when it boot again it gaves me an error:
try (0,0) : nfts5 : wubildr try (0,1) : ext2 :
and the windows7 says that i have to instal again. so i went to another pc and i made a cd boot and a pen boot. i burned the iso (downloaded from the ubuntu oficial site the 11.04 32 bit version) image to the cd and pen drive prperly, i adjust my boot options to star from usb or cd rom and nothing im struck.
my school we want to print a magazine but we have problem with the format of the files. We need to create a sheet in A3 format from two sheets in A4 format. I was reading about the pdftk library but it doesn't do what i need.
I suspect this is not new but I just can't find where it was treated. Maybe someone can give me a good lead.I just want to prevent certain users from accessing CD/DVD drives and all external drives. They should be able to mount their home directories and move around within the OS but they shouldn't be able to move data away from the PC. Any Clues?
I have Fedora 14 installed on my main internal drive. I have one Fedora 14 and one Fedora 15 installed on two separate USB drives.When I boot into any of these drives, I can't access any of the other hard drives from the other drivesll I can, but just the boot partitions.Is there any way of mounting the other partitions so I can access the information?---------- Post added at 12:42 PM ---------- Previous post was at 09:34 AM ----------I guess even an explanation on why I can't view them would be good too.
I have 2 CPUs Which are Intel and AMD based. I used F9 before and didnt have any issues while I removed the hdd that I'd installed F9 on INTEL based and then put my hdd on my AMD based cpu. Well it booted and ran perfectly no issues came up.And then I've done the upgrade to F10 (clean install on INTEL). I do the same case above.But I got error msgs it said that the UUID cannot be found (I was using label on F9 fstab and worked fine).
I put back my hdd to intel based cpu and then try to edit my fstab and menu.lst (change UUID to LABEL). WOW I thought by changing UUID from fstab and menu.lst would resolve my problem but it doesnt solve anything. My devices (sda1/2/3, /boot, and /home) cannot be reconized.Well do you guys know how to change UUID to LABEL? and what exactly my problem?
So I recently set up a fedora 13 server using software raid. Let me go over the initial install and maybe that will help explain why I'm running into problems with one of the arrays. During installation I had only 2 disks in the equipment (WD 750GB each) Partitioned them thusly:
when my grub references the UUID for the root= parameter, I get a kernel crash. If I change the root= parameter to /dev/<partition>, grub boots without a problem (f13 64-bit)
I am currently running Fedora 14 on a 32-bit AMD XP motherboard. My plan is to replace the motherboard w/an AMD 64-bit (multicore, prob'ly) version (most likely w/a different h/w architecture) and I'd like to make sure my current applications and configuration (if that makes any sense) are moved en masse to the 64-bit version.
Is there an easy way to do this? What are my "gotchas"?
