Hardware :: UUID Not Resetting With USB Enclosured SATA Hard Drives?
Jan 11, 2011
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 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

(Ubuntu 10.10) I went to System->Preferences->Power Management and checked spin down hard disks whet possible. I have two internal sata hard drives. One is for the OS and the other is for media. Neither Hard disk is being spun down. Is there something else I need to do?

I have a 3 year old PC with 4 internal SATA ports. My old SATA hard drives, all smaller than 2TB, work fine. If I buy a 3TB SATA hard drive, will it work in Linux? Will Linux with GRUB be able boot from such a hard drive without a BIOS upgrade? With a BIOS upgrade? It's fine for me to upgrade my Linux to the newest kernel.

I have three 640GB sata hard drives that I would like to put into a raid 5 configuration. I would like to opt for a software raid 5 so its hardware independent. I was trying to follow these instructions, but they seem a bit dated.

I recently finished installing Fedora 9 on a Prolient ML 330 G6 Server, but i configured the SATA hard drives to be viewed as four seperate hard drives. I was asked to merge the drives to be seen as one 800GB hard drive, my biggest fear is that we had set up Samba to share folders between fedora 9 giving specific users access to specific files saved on the Prolient server, will those settings be lost.And could you call that a File Server or do you have to enter any more settings And also if anyone could point me to a tutorial on Logical Volume Management and Raid specifically for fedora 9

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?

I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/)Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?

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

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 tried installing Red Hat linux on my Sata hard disk . As soon as the hardware detection phase starts it generates the error "No hardware detected".roblem? (I have also tested RHLE 5, CentOS 5.4, but none of them detect the hard disk and I can not install anyone).I have installed Windows 7 on one of my disks and I have not any problem with it.I also changed storage configuration in Bios as AHCI, IDE,
My Hardware config is as below:
Mainboard: ASUS P6X58D premium,
CPU: core i7 950,
HDD: two 1 TB WD SATA3
Ram: 6 GB (3*2 GB cruciall[/U][/U][/B]

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 have a 500gig SATA drive and a 320gig IDE drive installed in an HP a6700y/9150e 1.8GHz Quad, 4 gig ram... The Fedora installer only sees the 500g SATA drive, and not the 320g IDE drive where I want to install Fedora. Now I know that I can't always get what I want, but in this case I am not willing to mess with the working Vista installation just to get Fedora installed.
Vista BTW sees the 320 just fine. I am clueless as to where to begin with this. I gave up in Fedora with my Celeron based machine because of speed issues.... But this new box should have more than enough horsepower to run F!

Does anyone know if fdisk is currently blind to SATA drives? If so, is there an alternative command one can use to list ALL partitions, mounted and unmounted, that are available to the system?

I am attempting to install F11 from full media onto Abit IP35 Pro m/b connected to two (unitilized) Seagate 300GB SATA drives (7200.9) and attempting to create a software RAID1 setup as I have in FC8. I am using the graphical setup (as I have in other releases.) However, the ONLY "drive" shown when creating a RAID partion is /dev/mapper/nvidia_jhhdfjhf with free space of 286165 MB. There is not /dev/sda0, /dev/sda1 drives that I would have expected to see.
NOTE: All BIOS options for SATA are set to "IDE", not RAID or AHCI. The Seagate Seatools software sees both SATA drives and all tests are successful. What now? It seems like this is a major step backwards from F10. It does not seem mere mortals can install with RAID1 on this motherboard.

I realize this has been asked many times before, but I'm fairly certain I've read through the majority of those threads and haven't found a working solution yet. I recently built up a Ubuntu Server 10.10 x64 box for backups, serving up files, and development activities. The server is running SATA drives in AHCI mode. Because this is a file server I have quite a few hard drives installed, which are currently a mix of WD 1TB Black and Green drives. I'm attempting to get my non-boot/data only drives to spin down after 10 minutes. I've tried the following:
1. Edit hdparm.conf with the following, replacing 'b' with the identifier for each disk:
Code:
/dev/sdb {
spindown_time = 120
}
This fails, and based on my research I'm pretty sure udev isn't properly running the hdparm configuration anyway.
2. I've also tried manually setting the spin down time with hdparm as follows (via command line and through rc.local):
Code:
hdparm -q -S 120 /dev/sdb
Which states that it successfully set the spin down timer to 10 minutes, but this also fails as the drive never spins down.
3. Finally, I just forced it to spin down immediately with:
Code:
hdparm -y /dev/sdb
This worked! Unfortunately, that approach isn't terribly useful. The drive stayed spun down for 20 minutes (thus far), so I haven't bothered to run iostat, etc to try and figure out if something is keeping the drives active. I don't believe there is because one of my drives isn't even mounted currently and it also won't spin down automatically.

Just what the title says ... I'm trying to install Ubuntu 10.10 and it does not detect either 300G SATA drive in my system. One of them is /home for my non-OS software and the other is used for data storage.
It does detect the drive (SDC) where I have 9.04 installed, but /home is on one of the SATA drives. Where to start? 9.04 works just fine, but I'm running tio problems with FLASH web sites insisting I have to upgrade Flash and Adobe doesn't have anything for 9.04.

The system is running great in fedora 7 or 12 with 6 sata drives installed. I tried to install 2 more sata drives(total 8 drives), tested some combinations: 6 drives in sata ports and 2 in sas ports, or 2 in sata ports and 6 in sas ports... the BIOS can detect all 8 drives, but the fedora 7 and 12 just detect 6 sata drives. It could be problem of sata/sas drivers of Linus. The chip set: Intel ESB2(6 ports) + LSI 1068E SAS controller(8 sas/sata ports) Linux: Fedora 7 and Fedora 12

I asked this on an Ubunut forum about a year or so ago but got no response. I have an Asus M2NE-SLI motherboard. All my HDD's are Sata. I have 2 burners - both IDE. For windows, it see's my hard drives in the order I have them setup according to their cable placement on the motherboard (Sata ports 1-3, Sata 4 I have set for external sata). However within Linux - and I mean any linux distro I've tried (Gentoo, Sabayon, Ubuntu, Mint, Fedora, even Gparted) see's my Sata drives completly out of order.
For example:
Sata Port 1 - Primary HDD - 500GB
Sata Port 2 - Secondary - 500GB
Sata Port 3 - Secondary - 250GB
Windows see's them as drives C:, D:, E: Respectivly Linus see's:
Sata Port 1: SDB
Sata Port 2: SDC
Sata Port 3: SDA
Or something like that. Its really messed up. Does anyone know what could be causing this? This causes all sorts of problems setting up a dual boot environment because Windows will place its boot loader on the Primary boot drive (Sata Port 1), Grub will install anywhere i tell it to, but because the drive order is messed up it breaks - unless I completely mess around with the drive order in the bios. I've resorted to putting Windows on one HDD, and Linux on an old external Sata for the time being, and use the Bios's Drive Boot Manager to select which drive to use. This is not the ideal way to run it.

i have 2 shiny new 1TB SATA drives. I have a running system already, basic install on a single disk. install both new drives & raid1 them on a single partition - mount them for storage. Seems simple but all i can find are howto's on instaling the whole system & booting on RAID.

I am running the 2.6.25.14 kernel on a RedHat 5.3 X64 bit OS. I am booting off a USB compact flash. When I put two hard drives in a test system the OS does not allow me to access either, however if I have one hard drive inserted I am able to mount the hard drive fine. Extremely strange. When both hard drives are inserted dmesg reports a sde and sdf, it just will not let me access them. I am not sure if this is a hardware issue or OS.
fdisk /dev/sde says unable to open. smartctl -i /dev/sde says NO Medium found. When I boot with only one inserted i am able fdisk. mount, etc... /dev/sde just fine. The USB controller has 5 slots to insert various media, but I am just using it for its compact flash slot.Why will the system play nice with one hard drive and not with two?

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 recently added 2 500GB sata drives to my machine. I have a Supermicro X6 mobo (yes its rather old) and the Bios recognizes the drives as Master 2 and Master 3 ide , but the linux will not recognize the drives. The system is running RH8 kernel 2.4.31 and i dont have the option of upgrading the kernel at the moment. Is there any way to get the linux to recognize the drives?
