Ubuntu Installation :: Not Seeing New 2TB Drives On 9.04?

Apr 28, 2011

This is yet another "I can't see my new disk" thread - sorry, I've had a good look at others and have tried the obvious but I'm stuck. I have a working Ubuntu 9.04 installation - 3 SATA drives, in a home made box on an Intel DG965WH mobo. It's been working well for a long time (which is why I've not felt the need to upgrade the OS) but I'm running out of disc space so I've just bought 2 new 2TB drives (Seagate ST2000DL003).

The board supports up to 6 drives - in fact in previous configs I have had 6 running before.

Now, however:
- the BIOS is seeing the new discs (so they are connected and powered)
- new block devices /dev/sdd and /dev/sde are being created, but I can't use them...
- gparted lists just the three old drives, not the two new ones, in its menus
- sudo fdisk /dev/sdd returns "Unable to read /dev/sdd"

I've tried disconnecting one of the drives - /dev/sde goes away as you'd expect but /dev/sdd still won't work In the BIOS, I have tried different settings - "Legacy" and "Native", makes no difference As far as I can see, 2TB shouldn't be too big to worry the OS.

Ubuntu Servers :: RAID-1 OS Drives - Setting Up A Backup Procedure For The OS Drives

Jan 18, 2010

I'm breaking into the OS drive side with RAID-1 now. I have my server set up with a pair of 80 GB drives, mirrored (RAID-1) and have been testing the fail-over and rebuild process. Works great physically failing out either drive. Great! My next quest is setting up a backup procedure for the OS drives, and I want to know how others are doing this.

Here's what I was thinking, and I'd love some feedback: Fail one of the disks out of the RAID-1, then image it to a file, saved on an external disk, using the dd command (if memory serves, it would be something like "sudo dd if=/dev/sda of=backupfilename.img") Then, re-add the failed disk back into the array. In the event I needed to roll back to one of those snapshots, I would just use the "dd" command to dump the image back on to an appropriate hard disk, boot to it, and rebuild the RAID-1 from that.

Does that sound like a good practice, or is there a better way? A couple notes: I do not have the luxury of a stack of extra disks, so I cannot just do the standard mirror breaks and keep the disks on-hand, and using something like a tape drive is also not an option.

Ubuntu :: Dual Boot 2 *seperate* Drives \ Several 1.5TB+ Drives, And One Of Them Is Not Being Used?

May 1, 2011

I've used it once before but got fed up with the boot asking me everytime I turned my laptop on because I wasn't using it enough. I have Windows 7 on drive C . I want to keep it on drive C. I have several 1.5TB+ drives, and one of them is not being used. I want to dedicate it to Ubuntu, and be able to do a dual boot with my Windows 7 install. Is this possible? If it is, what about when this drive is not connected to my laptop? Will that mess up the boot process?

Server :: 2 Separate External Hard Drives With ESata To Minimize An Electrical Failure To The Drives?

Mar 26, 2011

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

Fedora :: Prevent Mounting Of External Drives & CD / DVD Drives

Oct 18, 2010

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?

General :: Files That Span Multiple Drives Drives?

Jan 8, 2010

So, at the moment I have a 7TB LVM with 1 group and one logical volume. In all honesty I don't back up this information. It is filled with data that I can "afford" to lose, but... would rather not. How do LVMs fail? If I lose a 1.5TB drive that is part of the LVM does that mean at most I could lose 1.5TB of data? Or can files span more than one drive? if so, would it just be one file what would span two drives? or could there be many files that span multiple drives drives? Essentially. I'm just curious, in a general, in a high level sense about LVM safety. What are the risks that are involved?

Edit: what happens if I boot up the computer with a drive missing from the lvm? Is there a first primary drive?

Installation :: Ubuntu Can't Find Drives / Get That?

May 16, 2010

I have two Sata 3 drives C and D, I have window 7 on C. I am trying to install Ubuntu and duel-boot My problem is when I load into the live disk the file system can only find the 1.8 gigs left on the live CD. If i run the installer it says no root file system is defined please correct this in the partitioning menu.

The problem is that the menu is completely empty. If I load Gparted in the live CD then it shows nothing at all except a message that says something like no device detected. Obviously the problem is that the installer can't find any were to put Ubuntu. Could windows 7 possibly be the problem?

If it's not possible on install, which maps should be moved from the C: drive to the D: drive if i want all applications and such on the D: drive? And how do i configure so futur installations from synaptic or the apt-get command install files on the D

Ubuntu Installation :: Installing 9.10 On Drives That Used To Be In RAID

Jan 11, 2010

I was recently given two hard drives that were used as a raid (maybe fakeraid) pair in a windows XP system. My plan was to split them up and install one as a second HD in my desktop, and load 9.10 x64 on it, and use the other for mythbuntu 9.10. As has been noted elsewhere, the drives aren't recognized by the 9.10 installer, but removing dmraid gets around this, and installation of both ubuntu and mythbuntu went fine. On both systems after installation however, the systems broke during update, giving an "read-only file system" error and no longer booting.

Running fsck from the live cd gives the error:
fsck: fsck.isw_raid_member: not found
fsck: Error 2 while executing fsck.isw_raid_member for /dev/sdb
and running fsck from 9.04 installed on the other hard drive gives an error like:

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

In both cases I setup the drives with the ext4 filesystem. There's probably more that I'm forgetting... it seems likely to me that this problem is due to some lingering issue with the RAID setup they were in. I doubt its a hardware issue since I get the same problem with the different drives in different boxes.

Ubuntu Installation :: 10.04 - Not Finding Hard Drives

Having a little problem with 10.04 installation. I have two hard drives installed on my PC. One that had Hardy Heron and one data. When the install program launches from a CD boot, it fails and drops me to a live session to check out the problem. I can see both drives and mount them but if I then launch the installer, it does not give either as an option for installation.

Ubuntu Installation :: Creating RAID-1 With Only 2 Drives?

Jun 27, 2010

I have recently installed a Asus M4A77TD Pro system board which supports raid.

I have 2 x 320gb sata drives I would like to setup raid-1 on. so far i have configured the bios to raid-1 for drives, but when installing Ubuntu 10.04 from the cd it detects the raid configuration but fails to format.

When I re-set all bios settings to standard sata drives ubuntu installs and works as normal but i have just 2 x drives without any raid options. I had this working in my previous setup but thats because i had the o/s on a sepreate drive from the raid and was able to do this within Ubuntu.

Ubuntu Installation :: No Hard Drives Are Recognized

Jul 18, 2010

When i try to install ubuntu 10.04 on my desktop i get through the first 3 steps which are Language, Region, and Keyboard. when i get to Prepare partitions, there is nothing there (same problem with 9.10). I followed the steps of another thread about removing the raid settings and I am sure i did that correctly but it did not work, when i try to find my drives in terminal they can not even be found.

Both of my drives are SATA, one is 250gb, other is 500gb. They are both recognized by other operating systems. I have switched the SATA headers that they are plugged into. I really am just not sure what else to do here. Im not totally stupid at linux, ive been using it for a few years and i have taken two classes for linux in the past year. I really feel dumb for not being able to figure this out :/

Ubuntu Installation :: Virtualbox Not Accessing Drives?

Aug 30, 2010

I am running Virtualbox with Win XP on Ubuntu 10.04, Everything is mostly ok, but I find two problems. I cannot seem to find a way to access my second (physical) harddrive as well as DVD writer. I have tried to add it to shared folders in Virtual box, but no go. I can , however, access my USB drives ok, after I found out about the Vbox user permissions. But what I do notice is that it seems Ubuntu unmounts the USB drive as soon as Vbox "mounts" it. Is there no way to have these drives mounted simultaneously on both platforms ?

Ubuntu Installation :: 10.10 LiveCD Won't Boot With Some LG Drives

Nov 17, 2010

A 10.10 LiveCD (burned from the ISO image) won't boot my system using my LG GSA-4167B DVD drive which has been working fine for several years.Upon boot, Ubuntu starts to boot up. The splash screen appears. The drive activity light flashes for a while and it sounds as if things are progressing. Then the drive gets into a funky pattern: click-click-spin fast. click-click-spin fast...

The purple splash screen is still present, with 5 red dots (not flashing) The LG drive happily boots up a Windows CD, BartPE CD, Ultimate Win CD, Macrium recovery CD, Gentoo distro CD, etc etc. Only the Ubuntu 10.10 LiveCD is problematic.Oddly, a 10.04 LTS LiveCD obtained with the book "Ubuntu for Non-Geeks" boots OK. (that CD is not burned at home). The LG GSA-4167B is 2005 vintage, with IDE interface. I swapped it for an even older (2004) LG DW1610 DVD drive. That drive boots the 10.10 LiveCD just fine.

I downloaded the 10.10 ISO image a second time and burned a second copy. Same results. The LG website had new firmware available for the GSA-4167B drive, so I downloaded that and flashed the drive. No change - it still won't boot the 10.10 CD. Are LG drives known to be problematic with Ubuntu? Are the CD-DVD drivers on the LiveCD limited in their functionality? If I go out and buy a new drive, should I avoid LG products? Perhaps I'l try burning the 10.10 ISO on to a DVD and see if that makes any difference.

Ubuntu Installation :: Mounting Ext3 Drives In 10.10?

Nov 18, 2010

It seems to be (we have experienced) that 10.10 can't handle having an older ext3 drive mounted to a folder on the 1010 ext4 drive. The files get "corrupted", but afterwards, putting the drive back into the original older 9.04 system, the files are perfectly fine again.

Ubuntu Installation :: Drives Switch Sda To Sdb On Install?

Dec 9, 2010

I'm trying to install 10.10 to my home desktop that has Win xp. I have one ide hd with only windos on it and I have a sata hd partitioned logically for linux. The sata controller is a via chip on an old Abit mobo. The live cd works great but when I run the install and get to the partitioning, my sata disk becomes sda instead of sdb. From the live cd, gparted shows the sata as sdb. From live, "cat /proc/partitions" shows the sata disk as sdb. But during install gparted shows it as sda. The install will go on the correct drive, but I'm not sure where to put grub2. On another distro install, I left it at mbr, and it went to the sata mbr. Should I just install grub to the ide disk which will become my "sda" at boot? Will grub find ubuntu on the sata disk, which will become sdb?

Ubuntu Installation :: Can't Mount Data Drives

Jan 9, 2011

I installed 10.10 on my workstation but now my system refuses to mount two existing two data drives that were already there... sudo mount /dev/sdc /mnt/data-b gives me: mount: unknown filesystem type 'isw_raid_member'

I didn't change any BIOS settings... My BIOS is not configured for RAID at all, that setting reads AHCI, which should be okay for my kernel (using the stock 2.6.35-24).

I tried to force mount one of the drives with sudo mount -t ext3 /dev/sdc /mnt/data-b

but this gives me an even stranger message:
"/dev/sdc already mounted or /mnt/data-b busy (neither of them are true...)

It's mainly the "isw_raid_member" thing that troubles me... I didn't and don't have a RAID system at all..

Ubuntu Installation :: Can't Mount Drives After Upgrade

Mar 10, 2011

a few days a go I got Samba messed up and I decided to just reinstall Ubuntu. Ubuntu resides on an 80GB drive and I have 2 1.0 TB drives that I use for storage. At one time (pre-Ubuntu) they were connected to a VIA SATA RAID card and I had them on a software RAID under Windows XP. Both worked absolutely fine under Ubuntu 10.04 (which had bee progressively upgraded from the original install of 9.04.

Now, both drives have been given the same label, and neither one will mount because the file system type is reported as "via_raid_array" rather than the EXT4 that they both should be. TestDisk can read them and identifies the partition as a Linux partition, and the data seems to be there. I have even reformatted one of them and still, it will not mount.

Ubuntu Installation :: Partioning New System 2 Drives?

Mar 18, 2011

setting up my new Laptop.

1st Drive = 90B SSD
2nd Drive = 500GB Sata
8GB = RAM

On my old system, I had one drive that was setup this way: 90GB drive will house all apps and system files, etc. 500GB would be for storage. like a huge /home. I looked at soem of the posts and I see people doing a /virt partition for their VM's. I do use a VM, but do not really understand the /virt partition setup... Definitely need help here. Need some guidance on how to best set this up. My plan is to clone the 90GB drive that will have ALL of my apps... If the 1st drive fails, I can just pop in another drive and not miss a beat...

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.
