View 3 RepliesJust 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?
I have posted in regards to fixing some problems I had after running recoverjpeg, and most are fixed. However, this process (recoverjpeg) continues to find pictures and dump them into my hard drive. I am fighting an uphill battle. Is there a way to stop a program from running continuously? I removed the package, but it continues to find files on my computer and put them into my hard drive, which is a problem.

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.
View 9 Replies View RelatedBeen 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 have a Nook ebook reader and would like it to automatically open a certain application when I plug it in.As standard it just opens a nautilus file browser.I cannot find any settings that will let me associate a drive name/uuid with a certain application and google results came up saturated with how to make bootable USB drives.The only solution I actually found was to make a .autorun script in the root of the drive to start my application, but it still requires user interaction and is not ideal since I would like to implement this across several machines with different users/applications.
View 1 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
[code]....
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
[code]...
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 recently scapped XP Pro on an old laptop (Toshiba Portege 7220)as it was so slow and I installed Ubuntu 9.10 - All installed ok and it worked fine for about a month. Last week I switched on, got the Ubuntu splash screen and thats where it stayed. I gave lappy to a friend of mine that knows about Pc's (hahaha). When I got it back he said he'd wiped the HDD and partially installed xp. The install apparantly hung after the reformat and copying files onto it.My problem now is I can't boot from HDD, Ubuntu Live CD or Windows CD - Laptop is set to boot from cd then hdd.When I try to boot from CD, the cd is read as I hear the drive being used also see light for cd flashing, after a while i get a blank screen with flashing cursor in top left corner and the cd stops.If I remove the HDD and put it in external usb caddy I can see the windows folders/files when plugged into my desk top.My questions are :-
1. Is there any way to make the drive reusable as a internal drive again as I know it works as an external drive.I would like to reinstall Ubuntu on it
2. Is it a fault with the laptop itself - how do I check
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.
I am running a hp dv701175nr laptop and am booting ubuntu 11.04 from a usb flash drive. I can not seem to find my internal drive that has windows 7 stored on it. I tried to mount it but it give me this error:
Error mounting: mount exited with exit code 1: helper failed with:
mount: according to mtab, /dev/sdb1 is already mounted on /
mount failed
I can't use this operating system if I can't access my windows 7 drive and I really want to use this OS .
EDIT: Okay, so I think I have found my problem, but I don't know how to fix it, there are differences in my mtab and fstab commands, I will post what they say in a second, but I do not know how or what I need to do to change and make the settings right
I 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.
I was wondering if it was possible to put something like a linux image on to a hard drive to install the OS on first boot. The reason I want to do this is because of the following reasons. First, I broke the IDE port on the mobo so I can't use the internal DVD drives on the computer.
Second, I don't have an extra SATA DVD drive lying around. Third, for some reason, this computer will boot from a USB DVD drive but once it starts loading the kernel, it just stops calling the drive and the computer freezes. I tested the disc and the drive with another computer and it works fine.And forth, the computer refuses to boot from a USB flash drive with linux on it. So as you can see, I'm in a bit of a pickle here. I would love to be able to hook the hard drive up to another computer and put the required files on the it for it to boot up to an installation.
I've been trying to find a way to watch videos from my main desktop computer on another computer I've plugged into an HDTV. I'm such a Linux newbie that I decided to give Mythbuntu a try. It was way to complicated for what I needed, and I'm sure that some more experienced people reading my first two sentences laughed to themselves at my naivety.
What I am trying to find is simple: browsing one computer's home folder from another computer, and playing the videos therein. If there's anything like Mythvideo that requires less than half of the skill requirements, I will telepathically send love to the person that informs me of it.
I accidentally formatted my internal HDD and unmounted it and now my computer won't detect it as a bootable device. I have a system recovery disc but it doesn't seem to be making any difference. Also I do not have my windows 7 installation disc nor can I write discs.
Is there a way I can fix this and keep all of my important files?

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 use ubuntu on a usb drive and Windows 7 as my main. The problem I have is that because I have a 1tb hard drive and a 1gb mem stick its really easy to chose the wrong on in the places menu as they are both 968 then either gb or tb which at a glance is hard to tell. Anyway I know the tb hard drive isn't mounted but I would like to know how to stop Ubuntu from even seeing the tb hard drive.

How can i find through terminal that which devices are external and which are internal.
By external i mean devices attached to USB port. For Example, USB Drive, Portable USB HardDrive etc
By internal i mean devices attached internally. For Example, SATA Harddisk etc.
I can't mount it, and also since apparently debian doesn't care about the nasty systemd but I had to deal with that but I digress.
I cannot mount my itnernal drive, and even memory cards are listed as "permission denied" even though I am part of the disks group. I know that before systemd I could just edit a udisks config file but I cannot find out where it'd even be.
I've included my /etc/fstab.
Code: Select all# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
[Code] ...
I am part of the disks group, and am 90% sure that I edited the udisks file that says something about mount internal disk to allow active from allow_admin
The only udev rules that i've changed was the one to change the mount point for external drives to /media/drive_label instead of /media/$username/drive_label
Basically I'm trying to automount the partition after clicking on it in the file manager.
I've just loaded Vector Linux on my computer (it's a Pentium 4/2ghz my father-in-law gave us). It seems to be working well, however, I have a second hard drive in addition to the boot drive. This drive is from a previous computer that ran Mandriva Linux, so I would imagive VL can read it. I can't seem to locate it anywhere using the gui. However, I checked the system settings window under "storage" and the drive shows up. It doesn't show up in the "devices" area of the system tray. I don't think I can navigate to the drive using the "file system" window either..Is there something I can do to -- one, find the drive; and two, add the drive to the devices window so I can mount it when I need to (or, preferably, keep it permantly mounted -- like on a mac or windows computer)?By the way, the drive was the boot drive for the Mandriva computer, but the jumper is currently set to "slave."
View 1 Replies View RelatedI've been thinking of buying a new internal hard drive, mostly because my 40 GB drive is beginning to get a little crowded. I haven't bought a hard drive in many years, so I don't know what brands are currently reliable. Years ago, I heard that the larger drives were much less reliable, but in recent years I have heard that is no longer true, so that it is cost effective to get a larger drive.
View 14 Replies View RelatedI went through the Fedora 11 DVD setup process up to the partition screen, which does show my external SATA drive correct as; /dev/sda when connected by eSATA, but it shows the internal drive which is a standard IDE, as; /dev/sdf , when it should be as; sdb, why ? I did run that fdisk -l in a terminal from one of my other installed Linux, and it did show drives as correct, ( sda, sdb ). I think this may be a issue related to the digital media card reader built into this 2006 Gateway desktop computer being detected as drives like Windows does and assigns drive letters, or is this some bug in Fedora 11 ?

I've just put together a new machine and as I expected, there are some issues with hardware. I've just tried to set up the installation of ubuntu, got to the partitioning section and only my external hard drive is being picked up. The internal hard drive is a 1TB SATA drive plugged into a 6GB/s DATA port on my m/b (Gigabyte GA-P55A-UD4 running Intel i5 760 processor). I'm probably going to try the alternate CD to see if that works, but does anyone know if this is a common problem for any of my hardware? (I did a google but couldn't find anything).
View 3 Replies View RelatedI have a 160 GB drive on an Acer laptop. First 80 GB contains Windows XP. The second 80 GB .. unused .. is a logical partition with an unformatted 80 GB.
I booted ubuntu 10.10 Live CD to format the second half of the drive for installation of ubuntu in dual boot but in separate partitions. I didn't get that far.
When I launched GParted a crash icon appeared in the top panel and GParted closed down asking if a crash report could be sent.
This crash I saw also in xubuntu Live CD.
What other options do I have to partition the second partition (logical)? What would cause Gparted to crash?
I would like to triple boot vista, opensuse and ubuntu.
I need to set aside 165 gb for Vista (which has been backed up to an external drive).
Would like to make a fresh install of Ububtu and Opensuse with Ubunto being the main OS. I figured 100 GB for Ubuntu and 55 GB for Opensuse would probably be fine (the remainder I need to set aside for Vista).
Ive popped in the Ubuntu DVD and am about to install it but am stuck on the "allocate drive space" part. I do not understand how to partition the hd and what to set each partition to in the "Use as" and "Mount Point"
