I have two encrypted partitions which I cannot find UUID numbers for.
/etc/crypttab looks like this:

and *sometimes this works, other times I have to edit the file and /etc/init.d/cryptdisks restart.
Obviously I should use UUIDs here and in fstab but blkid does not list those partitions

I have a debian 6 system in my basement acting as a media server. Debian is on a separate HDD from the raid drives and there is one external drive. Under normal conditions the Debian HDD shows up as /dev/sdk and the external shows up as /dev/sdl, no problems here because I use UUID for mounting. The problem is sometimes this drive isn't picked up on restarts (its old and I think the issue is the power supply in the base of it, to be solved later) . This wouldn't be a problem but it some how shuffles the drive addresses and the Debian HDD becomes /dev/sde, this in turn messes up a script that does a weekly dd of that hard drive. I am only really worried about this for when I go on vacation and I wont be at home if the power goes out.
So, is there a way to address the entire hard drive (not just a partition) other than the dev file? Why did this change from Debian 5 to 6? I never had this problem before with 5.
In case you are wondering, I find it easier recover from an image rather than do a reinstall, then get all the updates and software, then put in all the backed up files.
I am running Debian 3.2.0-0.bpo.2-amd64 on hyper-v, my / volume ran out of space and is sitting at 100%, I have extended the disk size on hyper-v, however when I go to Fdisk I see duplicates of each disk.
I have total of 2 vhds on the vm, so I see 4 disks under fdisk. Here is the output of fdisk

where is uuid of partitions of raid0?
My box is centos 5.4 x86, and dual booting with windows 7. I need to make a ext3 partition between ntfs partition 2 and 3.
After making this ext prtition, I need uuid of this ext partition.
I have a mounting rack in which I try to plug in various HDDs. Now, all of them have vfat. Blkid returns something like:
/dev/sda7: UUID="4B16-F1E8" TYPE="vfat" The UUID looks abnormally short to me. I found no way to obtain a longer, typical UUID, and when I set Yast2 partitioner to mount by UUID, it sees and it successfully uses the short UUID. Yast2 even adds it to /etc/fstab like this: UUID=4B16-F1E8 /windows/C vfat users,gid=users,umask=0002,utf8=true 0 0 However, this short UUID is useless in /etc/fstab. It doesn't work at boot time and it doesn't work when I try to mount manually. xxxxx:~ # mount /windows/C mount: special device UUID=4B16-F1E8 does not exist. Also, one cannot find these short UUIDs in /dev/disk/by-id/.
For a billion reasons, I really want to mount these FAT32 partitions by UUID. Do I have any way to do it?
I have 2x 1.5TB hard disks and I'm going to buy a new 2TB drive soon. First though I just wanted to check that I could partition off the first 1/4 to 1/3 of the 2TB drive (leaving 1.5TB or more free) and install Debian to that part, then use the remainder of the disk in combination with the 2x 1.5 TB drives in RAID 5? i.e. can you mix whole drives and with partitions from other drives in RAID 5 and/or is it best to just stick with complete drives for the RAID array?I only have room for 3 drives in the small mATX case that houses my NAS device and I want to maximise storage capacity and minimise expense.

The process to mount partitions seems to be happening before the service /etc/init.d/lvm2 is started. I can get it mounted using "mount -a" command, but not during the boot time. What should I do get it automatically mounted on every boot?

I'm setting up the array by doing as follows:
Delete existing device (I've done this a few times):
Code: Select allsudo mdadm --stop /dev/md0
sudo mdadm --remove /dev/md0
Zero drives:
Code: Select allsudo dd if=/dev/zero of=/dev/sda bs=1M count=1024
sudo dd if=/dev/zero of=/dev/sdb bs=1M count=1024
Create partition tables:
Code: Select allsudo parted /dev/sda mklabel gpt
sudo parted /dev/sdb mklabel gpt
Create full-disk partitions:
Code: Select allsudo parted -a optimal /dev/sda mkpart primary '0%' '100%'
sudo parted -a optimal /dev/sdb mkpart primary '0%' '100%'
Set raid flag on partitions:
Code: Select allsudo parted /dev/sda set 1 raid on
sudo parted /dev/sdb set 1 raid on
Create RAID array:
Code: Select allsudo mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sd[ab]1
Add filesystem (I'm using NTFS, but the problem also happens with ext4)
Code: Select allsudo mkfs.ntfs -f /dev/md0
On my system nearly all subfolders of my home-directory are on another hard drive. I included them via /etc/fstab as shown in the example below:
UUID=12c12565-ece4-4a22-b5c5-275aba1a3fd4 /media/data ext4 defaults 0 2
/media/data/archive /home/XXX/archive none bind 0 0
etc.
What would be the best way list disk and partitions in the fstab file?
View 1 Replies View RelatedUsing Linux, I have several backup levels. One of them is a periodical sector by sector copy (using dd) of my laptop harddisk to an external USB disk. Yes, I have other backups too, like remote rsync. This approach (the disk dd) is OK when cloning a HDD with no LVM volumes, since I can plug the external disk anytime and mount the partitions simply mounting /dev/sdb* instead of /dev/sda*. Trivial and handy.
Today I moved ALL my harddisk (including the /boot) to LVM. Everything works fine. I will stress it for a couple of days, and then I will do a sector by sector copy to my external harddisk. Now I have a problem, I guess.
If in the future I plug the external USB HDD to recover any file, the OS will detect a duplicate LVM configuration, with the same name and the same UUID. Even doing a vgrename (which LVM would be renamed, the internal HDD or the external HDD?), the cloned UUID will not change. Is there any command to change name and UUID? Ideally I would clone the HDD and then change the LVM group name and its UUID, but I don't know how to do it. Another related issue would be... In the past I have booted my laptop using the external disk, using the BIOS boot menu and changing GRUB entries manually to boot from /dev/sdb instead of /dev/sda. But now my current GRUB configuration boots directly from a LVM logical volume, something like: set root='(LVM-root)' in my grub.cfg. So... What is going to happen with duplicated volumes?
I have, as I have in the past, copy/pasted a partition using gparted to get a working OS to another place.
I have always done this in the past to a different drive. Never paid much attention to the UUID.
This time I did it on the same drive. The partitions have the same UUID. This is not a good thing.
The copied OS boots and mounts fine as I edited the fstab to go by /dev/sdxy (where x is the drive and y the partition). My grub uses a custom menu using symbolic menu entries so it goes by the partition definition instead of UUID too.
I would really like to change the UUID on that partition.
I am running Wheezy as my main OS in the first drive in my desktop. I use the 2nd drive for data. I am trying to add another OS to multiboot. When I ran grub-update in Wheezy, I am getting device letter for the root device instead of UUID in grub.cfg, in the os-prober section. Like this
Code: Select allsearch --no-floppy --fs-uuid --set=root 6ee49a8e-a619-49c7-9f66-51a5ca9a48cc
linux /boot/vmlinuz-316-x86_64 root=/dev/sdb3
initrd /boot/initramfs-316-x86_64.img
In the same file, UUID was used for the existing kernels.
Code: Select alllinux /boot/vmlinuz-3.2.0-4-686-pae root=UUID=c2eecf02-d427-4f2e-9fd0-9db61256cbac ro quiet
echo 'Loading initial ramdisk ...'
initrd /boot/initrd.img-3.2.0-4-686-pae
How can I get UUID instead of /dev/sdb3 for the 2nd OS?
System Fossil age laptop, Debian testing with lilo. SymptomAfter an upgrade (2nd week May), custom kernel compiled, kernel panics on boot, saying unable to mount root drive. (or more precise, unable to mount whatever uuid device). Stock kernel can boot. Workaround Instead of uuid on kernel option, use prehistoric root=/dev/XXX.
edit:The kernel which panics is 2.6.38 (make oldconfig, all default answer from 2.5.32 config)Stock is 2.6.32 On 2.6.38 after boot with tweak, the command "uuid" looks good.
Been doing some installations in a newly upgraded machine where I'm setting up two instances of 8.2 in slightly different configurations.Installing from netinst AMD64 DVD with firmware non-free. First installation goes smooth as then the second changes the UUID of the swap partition, meaning that the first then can't find it. To add insult to injury the second installation doesn't install GRUB in the MBR of the HDD.
Nothing different or special about the installation which is standard graphical with manual allocation of previously set up partitions. I don't touch the swap drive in the partitioner - just point to the correct partitions for / and /home as I want them. This is exactly as I've done before, many times.Setup asks me if I want to install GRUB in MBR and I answer "No" (because it would otherwise load in MBR of sda where I want it on sdb) then point to sdb in the next screen. Again really nothing different to what I've done dozens of times.
I am using Debian lenny (kernel 2.6.26-2-686).
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.
Upon booting my LVM wheezy setup, I get
fsck.ext3: Unable to resolve 'UUID=theUUID'
where "theUUID" (without the quotes) is the UUID
I believe this is caused by me trying to get lvm to use the external /boot because when I had unmounted the external /boot, it was creating a /boot in root. So, I booted a live cd and mounted the external /boot where /boot in the root volume is supposed to be. Basically, I think the problem is that I need to make my /boot (which is the only ext3 partition in the entire system and I want it that way) "relate itself" to the lvm root so that it boots into the system. As mentioned earlier, in the live CD, I made the external /boot mount itself in the root's /boot but I don't know how to tell the system to do this on its own while booting without my assistance. I chrooted from the live cd which involved a lot of tedious stuff but basically the important stuff I did were:
grub-install /dev/sdb
update-grub
update-initramfs -u
P.S.I get the issue in the Subject of this topic by telling tune2fs to mark the external /boot, lvm / and /home partitions as "dirty."
UUIDs make fstab hard to read, so.. Is it possible to use udev rules to prevent HDs to change device, instead of using UUID in /etc/fstab?

Since I am still very much a newbie when it comes to terminal commands, I stayed away from the manual recovery and pressing S just puts me back into the welcome screen so I can log in. I've been searching the forums and I can't find much on it. Maybe I am missing a really important factor here? Also, in some version of the instructions, the other partitions are supposed to become viewable once mounted. I went into looking through the files using PySDM, but what I saw was mostly greyed out files...

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.
