Ubuntu :: 10.04 Not Reading Other Hard Drives In Machine
May 1, 2010
I have a machine that is dual booted with win vista. It has 3 HD's. I created the partitions for the non-bootable drives in windows, ages ago. Prior versions of ubuntu would detect the drives, when I clicked on them in nautilus, I was prompted for my password, then the drives were mounted for the rest of the session. any idea how to mount these drives properly? The documentation linked to above describes ext3 and fat32 file systems (I tried both)

After a reboot (why did I do that???) one of the hard drives on my machine refuses to mount with the following message:
Code:
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
missing codepage or helper program, or other error

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 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 having problems reading burned media from my optical drives. I can burn media but after it's burned my drives do not read them, but if I use a different system it reads just fine.I am a newbie at this so I have no idea what I did wrong.

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 a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.

Earlier tonight my computer froze when I was moving some folders on an external hard drive (ntfs) and I had to manually shut down. Now nautilus crashes whenever I try to access the drive, although if I open nautilus as root it works fine.

I've a faulty hard disk I'm trying to read data from before I send it to the professionals. The disk makes some "good" mechanical noise when plugged into an IDE-USB header into my machine, so I think it's spinning up OK.
Under Windows, the disk is seen in admin tools but I can't do anything to it; it's unreadable and unalterable.
Under Linux (Ubuntu), I see the sdb appear in /dev. No partitions though (no sdb0 etc). At first, I thought this implied that my MBR was bad and the partitions could not be found. But, using dd suggests it's a little worse that:

I have been backing up onto a 60G ext2/3/4 partition on a 1TB external USB hard disk for a year or so now and have built up a few folders of .thunderbird, .mozilla, and other assorted files - using this as my standard "backup system" - but suddenly all the files and folders in this partition seem to have disappeared.
In Gparted and KParted the partition shows up as the correct size with the correct amount of "used space" (= yellow coloured portion), as it does when running offof any CD/standalone OS. And the small bars under the volume names in Dolphin show about the right amount having been "used" too.But however I try to access this partition (or, to be correct LVM I spose:-)) it still always comes up as empty - ie 0 files in it. After months of working just fine.The NTFS partition on the same external USB sdd reads and writes quite OK/normally and also shows the correct amount of "used space" - but even from root I can't see any of the old files in, or read/write to the linux one. It comes up with "Denied"/"Can't Write to.." errors when trying to write anything to it.
I ran a freeware utility called DiskInternals Linux-Recovery from winDoze which, after half an hour, came up with a list showing all the folders and files in the partition. It said that they would be written back onto the hard drive that they were "retrieved" from - but no change happened - still no contents showing when booting up in any linux.

I have a Centos 5.5 system with 2* 250 gig sata physical drives, sda and sdb. Each drive has a linux raid boot partition and a Linux raid LVM partition. Both pairs of partitions are set up with raid 1 mirroring. I want to add more data capacity - and I propose to add a second pair of physical drives - this time 1.5 terabyte drives presumably sdc and sdd. I assume I can just plug in the new hardware - reboot the system and set up the new partitions, raid arrays and LVMs on the live system. My first question:
1) Is there any danger - that adding these drives to arbitrary sata ports on the motherboard will cause the re-enumeration of the "sdx" series in such a way that the system will get confused about where to find the existing raid components and/or the boot or root file-systems? If anyone can point me to a tutorial on how the enumeration of the "sdx" sequence works and how the system finds the raid arrays and root file-system at boot time
2) I intend to use the majority of the new raid array as an LVM "Data Volume" to isolate "data" from "system" files for backup and maintenance purposes. Is there any merit in creating "alternate" boot partitions and "alternate" root file-systems on the new drives so that the system can be backed up there periodically? The intent here is to boot from the newer partition in the event of a corruption or other failure of the current boot or root file-system. If this is a good idea - how would the system know where to find the root file-system if the original one gets corrupted. i.e. At boot time - how does the system know what root file-system to use and where to find it?
3) If I create new LVM /raid partitions on the new drives - should the new LVM be part of the same "volgroup" - or would it be better to make it a separate "volgroup"? What are the issues to consider in making that decision?

i have 2 hard drives showing up on my desk top and when i try to unmount them i get an error
Error unmounting: umount exited with exit code 1: helper failed with: umount: only root can unmount /dev/sdc1 from /media/new movie storage
and
Error unmounting: umount exited with exit code 1: helper failed with: umount: only root can unmount /dev/sdb1 from /media/STUFF
when i try to unmount the other one. now one problem i see is that the labels are wrong the error for /media/stuff came up when i tried to unmount /media/new movie storage, and and the other way around for /media/stuff. also new movie storage is labeled as safe every ware else including inside windows

Earlier I had two physical hard drives in my computer, one with Windows and one with Ubuntu. Now I have a new computer and have installed these hard drives in it. I run Windows 7, and I can find the Windows disk, but not the Ubuntu disk. This doesn't surprise me, as Ubuntu is another filesystem, however, earlier I could format it with a partition manager, but now I didn't even find it with that!

Is there any software that could help me with this? Does anyone know of a better to do something like this?

I have a nice computer i have been dual booting between either ubuntu or win7. i am wanting to remove win7 and install winxp sp3, so i can use media center with my xbox. i preferred that win7 work, but since my copy is not genuine, its authenticity is believed to be the culprit in connection errors with the xbox. i have not been able to find a linux alternative, which i doubt even exists due to the proprietary nature of the xbox.
So, my question is how do i reformat the win7 hard drive? are there issues i need to worry about that may reformat both hard drives on accident? and when the hard drive is formatted, will i be prompted to choose which hard drive to install win xp on?

My computer has 2 40GB hard drives (yes, it's really old). One of these hard drives has Ubuntu installed on it, and I would like to use the second hard drive as a data storage device that is usable by anyone who just wants a random place to drop random stuff. How do I do this?

I am trying to install windows 7 over Ubuntu, however when i run the install disk it tells me that my hard drive is not formatted in the correct format. I have then loaded up Ubuntu, tried to re-format using Gparted and it won't let me re-format my hard drive when I right click on it. The only option I get when right-clicking is to unmount the drive.

I have ubuntu 11.04 installed on a 80gb hard drive and everything was running fine. I then installed a second drive (1gb) for storage. It worked fine after a reboot but now it won't boot. I'm pretty sure it's just confused as to which drive is the boot drive. I'm not sure as to how to fix it in GRUB2.

I have two machines, a laptop and a desktop, both running Lucid. each works fine, but... I can't seem to mount the external drives attached to either machine over the network. I can share folders from the internal drives fine but when I try to access an external drive from either machine I get "unable to Mount volume". Is it possible to mount the external drives across the network? If so, How?

I want to make a RAID5 array with 4 2TB hard drives. One of the drives is full of data so I will need to start with a 3 disks and then once I copy the data from the 4th onto the array, I will then add the 4th drive. This will be my first experience with RAID. I've spent a few hours searching for info but most of what I have found is a bit over my head.

Going to be setting up a local home server ("headless") for the following:* General file sharing for home network -- a portion of this will be for movies which are accessed via Popcorn-Hour and a second PC hooked to another TV* MySQL storage for home network (bills, misc info, bookmarks, code snippets, etc.)* PHP Server for php scripts i write* SVN* misc Databases for PHP dBase testing (SQLite and Postgre) * Virtualbox* backing up stuffI have a bunch of hard-drives of different sizes, buffer size and access speeds.
Hardware* m/b supermicro X7SBL-LN2* Intel Xeon X3360 Yorkfield 2.83GHz 12MB L2 Cache LGA 775 95W Quad-Core Processor* (2) (8GB in total) Crucial 4GB (2 x 2GB) 240-Pin DDR2 SDRAM ECC Unbuffered DDR2 667 (PC2 5300) Dual Channel Kit Server Memory Model CT2KIT25672AA667
* (known hdd) Western Digital Caviar Green WD10EADS 1TB 32MB Cache SATA 3.0Gb/s3.5"Internal Hard Drive -Bare Drive
What would be the best way to set this up ?OS installed on fast hdd ?Virtualbox on fast hdd ?Movie storage on fast hdd's (mirror raided) ?As for raid, i plan on taking two (1TB) hdd's and mirror them for the movies and two more (smaller) mirrored for backup storage.Im pretty sure i would want the Movies stored on there own hard-drive (faster hdd with more buffer) so not to cause and "lag" incase the server is being used/access at the same time for another use (MySQL access or what ever).Currently the server machine is set-up using VMware which is where the current Ubuntu-server is installed to/on, but now i would like to have Ubuntu as the base and use Virtualbox as means to virtual hosting instead of VMware.

I have been going crazy trying to get Ubuntu 10 installed and working on my G3 B&W. When I boot into the live CD, hit Control-Option-F2 to get into a terminal, then do Fdisk -l, it only shows my CD-ROM. I got 9.04 to install, then updated to 9.1, then to 10, but when I reboot, I get the gave up waiting for root error. Tried typing exit, and changing the wait time to 90. I've spent a lot of time on this, and learned a lot. Anyone no how to get past this?

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.

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.

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 :/
