Fedora :: Get The UUID For Some Of External Hard Drives?
Apr 7, 2011
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 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.

I am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data

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 currently use Ubuntu Lucid, and I'm curious if there is a program that I can install and run through it which will defragment an external USB hard drive.
My 500GB hard drive is used a lot, and I often add/remove stuff on and off of it, and I'm sure it's slowly starting to get a little fragmented with the amount of deletion and addition I do on it.
Does anybody know of a way to check and potentially defragment just it through linux? Or am I gonna have to just find a windows computer and do it there?
FYI, I don't care to nor know I really don't need to defragment my Ext4 drive to which Ubuntu's installed, its' just the external I am curious about.

So me and my friend our on my network and we have done a bit of hacking and have managed to get music off of pandora and have it sort it by forlder /media/...../artist/album/song and it won't redownload a song that we have already downloaded (this is done by our code that we stripped from pithos and modified a bit) also we wrote a bash script that renames all of our files correctly and tags them with .mp3
I was wondering if I could link our two hard drives to make sure that we aren't both downloading the same songs. I am also having issues getting my external accessible on the network i have it formatted to use a FAT32 file system.

I have an external hard drive that contains some 600 GB of files and folders. I use this external drive frequently and so the files and folders in it change on a daily basis. I want to back up this drive on another external drive. What is the best way to sync these two external hard drives on a daily basis?I have been trying to sync them through the Grsync software. But I think either I am not choosing the right options or else Grsync is not the best/right software for my purpose because the second hard drive does not ever become completely identical to the first one. What am I doing wrong? Should I go with another software? If so, are there suggestions for a good one? Or am I doing something not right?
When I run Grsync, I choose the first external hd as my source and the second one as my destination.Then below that I check "Preserve time," "Preserve permissions," "Preserve owner," and "Preserve group." Below that, I also check "Verbose" and "Show transfer progress." Other options are all unchecked.Should I reconfigure these options?FYI, I frequently rename, edit, modify, or else completely delete files and folders in the primary hard drive. Hence, my need to back it up everyday so that the change would be replicated in the second hard drive.

How to mount multiple external HDD's. I'd like to link or mount the music, torrents, and general files from several external hard drives and apply permissions (in some cases I only want the mount or link to be read only).
My setup:
- Seagate Dockstar running Debian squeeze (it's headless so I don't have a gui running)
- Two external HDD's with one partition on each (250GB and 400GB)
What I'd like to accomplish:
1. Mount the external HDD's to /media/HDDs as read/write (this is already working using udev and autofs and it's available in samba)
2. I'd like the MUSIC directories on both external HDD's to show up under the same mount point. In other words I want the MUSIC folders (from both HDD's) to appear as one large library of music. And I only want this to be readonly. It will be used as the library for mpd and/or squeezebox.
3. Mount a directory used to download torrents to. I'll probably pick on HDD as the target for torrent dowloads. But let me know if you have any other ideas regarding this.
Since I have the first one done, how would I accomplish 2 & 3?

After some googling I found out that there might be a problem with highspeed external USB drives in Linux in general. Im using Ubuntu 10.10 32 bit and have now this problem I think. My external hard drive is working fine but when I type dmesg in a terminal I can see message errors that appear randomly with all my external hard drives. The problem is now, I have all my music on this drive and randomly I will have hangs while listening to music and the performance while tranferring data between my notebook and the USBs is poor. Anybody know a workaround for this problem or have the same experience or have more details about it? My principle USB device that I use is an iOmega 500 GB what I use on my Compaq 6730s. The other USB device is a Toshiba 1 TB. I tried to transfer the files into my homefolder to avoid this problem but there is no chance as on my notebook is no more space.

I have a FAT32 external USB hard drive with a bunch of stuff I want to copy onto a RHEL server. Is it as simple as it is on a Mac or PC where I just plug it in and it will show up, then I can copy all the files off of it?If it is, how do I safely remove the drive after I'm done with it?

I have set up two external hard drives to automount in fstab with the following lines:
/dev/sdb1 /media/DownstairsBackup ntfs-3g rw,auto,user,exec,sync 0 0
/dev/sda1 /media/UpstairsBackup ntfs-3g rw,auto,user,exec,sync 0 0
And right after I restart, all users have permission to read and write, and everything is fine. However, I have an automated backup utility (BackinTime) installed to back up particular (mounted network) directories every night, but whenever I check up on it the next day, I get the error "Unable to mount ..... Authorization required". (These network directories are mounted into the local filesystem in fstab as well.) Oddly enough, if I run BackinTime by hand as the users, it works fine. I'm running 10.04 LTS.

Months ago one of my computers died. I have bought a brand new one laptop, but I have a problem at the moment I wanted to install Ubuntu in dual boot with Windows 7: the new partition that windows 7 reserves for securing system files.
There are three partitions: Windows 7 principal, Windows 7 for securing system files (at the drive's beginning) and the recovery partition that HP puts there. Then I only have option to resize the Windows principal partition and get another principal partition. My question is if you know how to deal with this?
The other option you can help me is to advise me about some external hard drives to install ubuntu in them and don't touch the internal disk of my laptop.

1) Environment:
Ubuntu 10.04
2) Phenomenon:
External hard drives won't be automatically mounted after upgrading some packages...
I have a "not good" habit: I'd love to upgrade whatever suggested by Ubuntu upgrading center every morning.
However, after upgrading some packages for today, my computer won't be able to automatically mount external harddrives, including file systems ext4 and ntfs.
My question is:
1) How can I check what packages have been upgraded just within today?
2) How to make my Ubuntu be able to automatically mount external hard drives whenever I plug in a harddrive as before?

Because a lot of users are using laptops now, and many want externals hard drives for backups, is there a program in Ubuntu (cross-platform with Windows would be nice) that backs up files to an external hard drive when the external drive is plugged in or on a timely basis? All backup systems seem to have a timed system, but these systems have annoying pop ups if your backup location is non-existant (e.g. Deja Dup).
Use case 1: I plug in my external, the program recognizes that and starts a backup.
Use case 2: I leave my external in all day and every 6 hours, my laptop backs up my files to it.

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.

Having problems with external hard drives. I may be wrong, but I suspect they originated with an upgrade to 10.04 last Christmas. Around that time I also started using Amazon's S3 storage system, and, as a consequence, I stopped using my WD 80G external drive, previously used to backup my important files.
A week or so ago I decided to start using the WD drive again. I can't remember exactly what I did, but it wasn't happy - never caused any problems before. When I plug it in, the on-off light as the front keeps flashing on and off, and when I try to remove the drive I get the message: Error unmounting volumne An error occured while performing an operation on "My Book" (Partition 1 of WD 800BB External): The device is busy
Details: Cannot unmount because file system on device is busy Assuming the device had died - it's about 5 years old - I bought a 160G Samsung S-Series drive - my but they do look neat! Unfortunately, this doesn't seem to have solved my problem. I plugged the new drive in, and it happily appeared on my desktop. It seemed a good idea at the time, but I then started to format the drive - using the default option of FAT. All went well at first, but then the format process stopped.
My new Samsung drive now seems to be operating pretty much as the WD device, I can't copy to the drive, and attempts to unmount it generate a response similar to what's happening with the WD drive. Currently, although plugged in, I can't see the drive on my desktop, although it appears under Places. However, when I try to mount the drive, I get the message: Unable to mount SAMSUNG A job is pending on /dev/sdb1

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.

After a bit of searching, I haven't found a discussion on how to mount an external device using hardware attributes, though I am almost certain I have seen discussions on this in the past. The objective is to consistently mount an external USB drive at the same mount point regardless of the order in which a user attaches other external USB drives. For instance, if I run lshw, I can find harware properties of the device:
Code:
*-usb:1
description: Mass storage device
...
physical id: 6
[code]...
I'd like to identify this device by the serial number and mount to a pre-defined mount point (e.g. /mnt/extUSB). I can write a script involving lshw,dmesg, and mount but I vaguely recall a more clean/ preferred method.

Using 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 a fresh installation of Fedora 11 and I am having a hard time figuring out how to automount my storage drives. Each time I login, I try to access my various storage drives and gnome makes me authenticate asroot before mounting it. FSTAB lists only logical volumes but not my storage drives. What can I do to make sure these automount when I login?

I installed Linux on my Y drive, and all went well until I tried to boot into XP again. I can't access or install an operating system to my other three hard drives, C, X, and Z.I think that during the install my hard drives were changed to something other then NTFS, but Linux won't access them either.
When I use my Windows XP or Windows 7 disc, it says the drive has 0mb free, and it can't install until I delete the partition, then reformat. I don't want to do this obviously, because I don't want to format all of my data.When I go to Places > My Computer it lists my CD drive, Filesystem, and the Y drive. It doesn't show my other three hard drives.Under Palimpsest Disk Utility I can see my other three drives, but I can't access the data on them yet.

I ran smartctl and it says "unrecognized" hard drive. I recognized the hard drive the first time I ran the test. But now, it's unrecognized? How come? I don't know how or why this happens. How can I get rid of this problem and the annoying icon?
I tried to run Windows, then started getting errors? This is strange: I've been running Linux the whole day. I last used the Windows hard drive was 2 days ago. Now its screwing up. Window is screwing up the hard drive? HDD has too many bad sectors. didn't touch it, I didn't do much on it, etc? I do not understand?!
