Just added a DVD drive to a machine which had no drive before. When I boot I get the error about being unable to find the root drive by its UUID. If I unplug the DVD drive it boots as normal.
I'm guessing the root drive is getting a new name i.e /dev/sda2 instead of sda1 and thus a new UUID. How can I add the drive and fix the UUID issue in grub?
basically just wanting to find the UUID for my internal disc drive. Running Slackware 13.1
View 3 Replies View RelatedI have an mdadm linear array of 4 500GB drives. One of them had a few bad sectors, so I've dd'ed it to a new one (conv=noerror), and tried to start my array. Mdadm refuses, saying, "mdadm: /dev/md4 assembled from 3 drives - not enough to start the array."I had diffed different samples from different positions on the source and the mirror drive and confirmed they were identical. Checking the superblocks confirms three old drives still having their superblocks as expected, while the newly mirrored one has,
daniel@lnxsrv:~$ sudo mdadm --misc --examine /dev/sdf1
mdadm: No md superblock detected on /dev/sdf1.
- and,
daniel@lnxsrv:~$ sudo blkid /dev/sdf1

As before. The mirror apparently has no uuid, but the original does. To confirm my sanity, I did,
daniel@lnxsrv:~$ sudo dd bs=1M count=50 if=/dev/sdc of=./sdc && sudo dd bs=1M count=50 if=/dev/sdd of=./sdd && sudo diff -s sdc sdd
50+0 records in

How can the uuid not be the same when bit-for-bit from the very first byte of the drive, covering MFT etc., these two drives are identical according to diff?
I rsync the filesystem where I have my server to another HD. Now, when I try to boot I'm dropped at initramfs with an error. It looks like it's still looking for the root in the previous HD even tough I already changed /etc/fstab. It says it can't find the device with a certain UUID, and that UUID is from the previous HD.
Here's the full details: I'm running Ubuntu server 10.04 It has 2 hard drives. Every night it backups one to another with the command
Code:
rsync --archive --one-file-system --hard-links --numeric-ids --delete
I moved the HD where I have the backup to another machine and rsynced them with the same command I then changed /etc/fstab in the new machine. I also installed Grub on it When I boot in the new machine I get a error about not finding root. It says that a device is not present. It says the UUID of the device is looking for, and it's the UUID of the first HD.
I thought I only had to change /et/fstab but seems I am wrong.
I posted this first to thread 'Boot problem - "Gave up waiting for root device.", (initramfs)' then realized that I should start a new thread because the problem is not the same. On boot the splash goes black and nothing happens, On a recovery boot it drops into shell BusyBox and messages indicate that the root partition cannot be found. After booting from CD Gparted GUI partition information shows no label or ssid for the root partition sda2. The data for the root partition appears to be there. how to fix this? My /home, swap, and / are on separate partitions formatted ext3. I have a recent backup only for my data. I would like to avoid having to rebuild my system from scratch.

When I start the Live CD I can see my harddrive and access it. But when I start the setup, it cant find the harddrive and I can not choose it. Ive tryed more than one cd's and another distro (built on Ubuntu). The hard drive works fine, Ive got Windows 7 already on it (help me change back to linux). I know the computer works fine as I once used another computer to install ubuntu on the harddrive and then moved the harddrive to my computer.

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'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?
View 6 Replies View RelatedI cloned one of my hard drives to another, using Acronis True Image Home 2011.In the process, of course, fstab got copied verbatim from old to new.I then, using a livecd on a flash drive, mounted the new drive, went into fstab and rewrote the UUID's, using the numbers I'd gotten previously by doing sudo blkid.Now, the new drive had the UUID's revealed by that command.Then, I used boot-repair, from yannubuntu, to make that drive bootable, since it wasn't after the cloning and after the fstab rewrite.The drive is bootable, and it's mountable from a flash drive, or from the old drive.
I can access files either way.the fstab file on the new drive still has the old numbers, yet when I ran boot-repair, it apparently changed the UUID's for sectors 1 and 5 on the new drive.fstab seems to be irrelevant at this point, yet everything I read about it indicates that it is not only relevant, but necessary.I don't understand how I can be accessing the drive when the fstab contains UUID's that are no longer pertinent to any hardware on my system.
Fstab:
UUID = A / ext4 defaults 1 1
UUID = B /stor ext4 defaults 1 2
UUID = C swap swap defaults 0 0
and the error is:
fsck.ext4: Unable to resolve UUID = B.

I've been away from Fedora for a long time, since FC3/4. I seem to recall that at that time grub in Fedora used the standard drive notation such as /dev/sdax instead of the current UUID. Can anyone tell me why this change was made?
Seems to me that using UUIDs presents severe problems if a drive has to be replaced as the restore media (we all backup, don't we?) would not work without modification. How does one determine trhe UUID of a new drive to change the restore media? Sounds like a chickenand-egg routine. There must be some way which I haven't run accross yet. I do notice through experimentation that the standard notation still works, at least in /etc/fstab.
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."
I need to expand one logical volume which is now in 99% utilization. The volume group only have 5GB and they need 25GB more so that I can add 30GB. The disks will be coming from SAN Storage. If the SAN Admin can successfully add the disks to the server and I can see it, should I still partition it and change the type to Linux LVM?
I have tried just doing a pvcreate without partitioning and do a vgextend and it works without actually partitioning the disks. But when I do "fdisk -l", it actually shows that the disk don't have partition.
Whether I need to partition the drive to 8e (Linux LVM) before doing? Which one is better? Below are my steps and please let me know if this the correct one.
Here's my steps:
1.) dmesg | grep sd (to check the newly added disks)
2.) fdisk /dev/sdx (create primary partition and assign Linux LVM to type)
3.) pvcreate /dev/sdx
4.) vgextend VolumeName /dev/sdx
5.) lvextend -L+30G Volume01 /dev/Volume01/lv01
6.) umount /dev/Volume01/lv01
7.) resize2fs /dev/Volume01/lv01
8.) mount /dev/Volume01/lv01 /lv01
9.) df -h (check if resized successfully)
I have recently installed a linksys wrt610n router, as it has the ability to plug in and access a USB hardrive/memeroy stick. The hardrive already has info on it, and it's running NTFS file system (which after reading may be a problem) In the 192.168.1.1 router setup area I can see the hardrive, share the folders I wish, and seemingly grant access to it. I am sitting here on my Ubuntu computer trying to map said network drive, but I am unable to see it. However I can access it just fine from my wifes Macbook.
Any search has shown problems with Samba/Windows being resolved, but I can't find anything regarding this situation. I've tried the adive given here; [URL] I've also tried using the pyNeighborhood program, this program will atleast see the drive, but scanning fails, and I can not "mount" with it either.
I have a dual boot computer with slackware_64 13.1 and windows.
I have a 120G ide hard drive that I need to add to my computer.
Adding this hard drive changes the drive device id's and slackware won't boot.
as installed, my drives look like this:
When I add the extra hard drive, it looks like this:
I know there is a way to make an initrid and to use the uuid identifications for the drives, and even use labels instead of the long uuid's, but I'm unfamiliar with this process, so I was hoping somebody that's done this before might point me in the right direction.
I run a headless Ubuntu 8.04 server, which acts as a web, email and file server. I am sticking with 8.04 as it is a LTS release and will upgrade to the next LTS when it is released.
I have two external USB drives, that I need to mount at boot. I have been using /etc/fstab up until now, with the following entries:
Code:
However, as I gather from doing searches is quite common, occasionally I get an error during boot (causing the system to drop to a recovery shell) because the USB drives take time to wake up and the system hasn't found them by the time it reads /etc/fstab.
From doing searches, it seems there is nothing you can do to fstab to fix this, so you need to mount them using an rc.local script instead, using:
Code:
The problem is, as I have two USB drives, their /dev/sdxx location changes between boots. I thus want to use UUID codes as I do in fstab, however I haven't found anything about this.
Does anyone know how I can use the mount command and UUID to mount a drive in rc.local and what options I have to use the mount the drive with the same options that I am using in my fstab entry? Obvisouly, I can't refer back to fstab using the mount command, because then I will still get the boot error issue if they are listed in fstab. And there is no space internally for the USB drives as there is already two internal drives.
I am having a problem booting my PC after adding a new SATA drive.
The PC has 3 drives.
SDA is a 500Gb SATA drive
SDB is a 1Tb SATA drive
SDC is a 160Gb IDE drive
The PC boots from the 160Gb IDE drive.
If I now install a 2Tb SATA drive the boot fails, it starts off OK as in the Motherboard boots from the IDE drive but sometime into the boot the / directory cannot be found.
If I boot from a live disk and check out the disks with gparted, I find that the new 2 Tb SAta drive is SDC and he 160Gb IDE drive is now SDD. I expect this is my problem but I cannot work out how to change it.
Note fstab is using UUID designations - not sure if this is relevant.
I'm trying to get a second drive configured. I wasnt to use this to store pictures movie s, and have the ability to share them across the network.
Main drive is SATA 80 Gig New Second drive SATA 1 Tb I can see both drives in the bios, They show up in g parted I've formatted and partitioned the drive and and every time I try to create a folder or share in SAMBA it tells me the I'm not the owner. I thought I could install the second drive and then partition the drive and I would be good to go like windows this was not the case.
I'm using ubuntu 10.10 and I would like to add a drive to grub. I have windows xp installed on the other drive, but in order to get to it right now I need to change drive priority in the bios. So how do I go about adding this new windows drive to grub?

Adding a Second Hard Drive?
View 2 Replies View RelatedI've had Ubuntu for about 8 months now, and haven't really had any serious problems with it, or problems I couldn't find a solution for. This one is kind of weird and is really driving me crazy.There were two Seagate Barracuda's in my computer, and I added a third a couple days ago. At first, I was getting a grub 22 error, because they were in the wrong sata socket order, but now they're all in the order they were before, save for the third which is in SATA port 3. After the GRUB2 display, I receive a blinking cursor on a black screen. I can type whatever I want into it and nothing happens, and if I wait a few minutes it will eventually show a graphical login screen, then displays an exception and then boots to the graphical plymouth screen. Here's a section from my kern.log that shows the bit the login screen displays as well as the rest of the errors.

What can you do with adding a second hard drive..?
View 7 Replies View RelatedA local store built a brand new dual core system for me about a month ago with a 1TB drive and installed Karmic on the entire drive. I now have a piece of external hardware that requires XP and simply will not work in XP in Virtualbox. I have purchased another 1TB drive, and my thinking is to create an XP partition of about 2-300GB and leave the rest of the drive for another Karmic partition and dual-boot. I don't care which drive is primary (unless there is a reason I should).
I was thinking of unplugging the karmic drive and putting the new drive in it, installing XP on it, then adding the Karmic drive back to the system and editing one of the boot files to add the other operating system.
If so, which boot file should I edit? Which drive should be primary? Or, is there a better, easier way to do this?
I just switched to ubuntu and i love it!! The installation went flawless but i had a second hard drive while i had windows vista to store all of my media, i.e. mp3 and pictures. Am i able to access the stored information on the second hard drive in ubuntu? Will i need to delete the partition in order to use the second hard drive for future use? The second hard drive shows up in the disk utility application, but not in the computer/file browser section. The file system for the second hard drive is hpfs/ntfs.
