I'm trying to get a GBB36X (Gigabyte-rebranded JMB36X) RAID0 controller to work in F13, with no success. When I run dmraid, here's what I get:
Quote:
# dmraid -ay -v -d
DEBUG: _find_set: searching jmicron_GRAID
DEBUG: _find_set: not found jmicron_GRAID

things "seem" to work, first time I've really ever used dmraid (usually mdraid), but I'm worried about this error
dmraid -ay
RAID set "jmicron_STORAGE2 " was activated
The dynamic shared library "libdmraid-events-jmicron.so" could not be loaded:
libdmraid-events-jmicron.so: cannot open shared object file: No such file or directory
Two things, why no matter what I name the RAID in the jmicron bios is puts a bagillion spaces after it, and second, I cannot find the missing lib anywhere I've installed all the dmraid* packages.
I'm trying to rescue files from an Iomega NAS device that seems to be corrupted. This is the Storcenter rack-mount server - four 1tb drives, celeron, 1gb, etc. I'm hoping there's a live distro that would allow me to mount the RAID volume in order to determine if my files are accessible. Ubuntu 10.10 nearly got me there but reported "Not enough components available to start the RAID Array".

So here's my noob, simple question, please answer it in semi-noob-friendly terms I've been trying to install ubuntu for a while on my desktop pc. I gave it another go with 10.10 but I always have the same problem:
I've got two raid sets connected to an ich10r chip and they work fine in windows (2 samsung 1to + 2 raptors 75gb). Upon installation, dmraid only sets up the first raid set (Samsung array) but not the second one (Clean raptors intended for ubuntu). I don't have any other installation option, all my sata connectors are unavailable. So, is there a manual install solution? Can I force dmraid to mount the second raid set and not the first one? I think I read somewhere that this was a dmraid bug, but I can't find it anymore.
I have a Dell Inspiron 530 with onboard ICH9R RAID support. I have successfully used this with Fedora 9 in a striped configuration.Upon moving to Fedora 13 (fresh/clean install from scratch), I've noticed that it is no longer using dmraid. It now appears to be using mdadm. Additionally, I need to select load special drivers (or something close to that) during the install to have it find my array - which I've never had to do before with F9. While the install appears to work ok and then subsequently run, my array is reporting differences .. presumably because it is trying to manage what mdadm is also trying to manage. More importantly, I can no longer take a full image and successfully restore it as I could with the dmraid F9 install. Is there anyway to force F13 to use the dmraid it successfully used previously?
View 1 Replies View RelatedI've created a soft raid w/ 2x 1TB drives by using Disk Utility. (used for mythtv storage, not system, swap or anything else)
If I start the raid array in the Disk Utility mount and everything works as it should, but on reboot the raid array isn't started so I have to go into Disk Utility, start it, then run the mount.
How can I get it to start automatically?
I have created a RAID 5 array using the built in Disk Utility.This is great and formatted it with ext4, and mounted it.However on reboot in Disk Utility as RAID Array is not running and under state Not running, partially assembled.I have to stop the array then restart it, then mount it before I can access what is on it.Obviously this is not very good as I often have the system shutdown at night to converse energy, and having to do this every time it boots is a pain.Could someone please explain in plain english what I need to go to get my array to start and mount on startup

This Raid disk is just a data store, I'm not booting off of it. when I reboot the raid1 disk does not start. I have to go into Disk Utilities, stop the array and then start it. Then it comes up and I can mount it. I ran dpkg-reconfigure mdadm and it created a valid entry in mdadm.conf. but the array still does not start on boot. I want to have it auto mount with fstab but need to make sure the array starts first.

Ubuntu Server 11.04 i386. I've used linux on and off for years but only in small doses, so I'm really just at newbie level. I was running an Openfiler NAS, but decided to give Ubuntu+Webmin a try. And up 'til now I've been happy with progress. I have set up a RAID-6 array using 5 x 1TB SATA drives. I've ensured that the array is in a "clean" state, and now I want to do some failure testing. The problem occurs when I remove one of the drives in the array. I shutdown, remove a drive, then boot up. The array wont start at all, and comes up with this error during boot:
Quote:
the disk drive for /mnt/raidvol1 is not ready yet or not present
Continue to wait; or Press S to skip mounting or M for manual recovery
If I wait, nothing happens. Obviously the RAID array should start in degraded mode, but it fails to mount at all. When I press "M" to go into manual recovery and type "mount -a" I get the response:
Quote:
mount: special device /dev/RAIDVG1/RAIDLV1 does not exist
I have set BOOT_DEGRADED=true in /etc/initramfs-tools/conf.d/mdadm without success. If I reconnect the disconnected drive, the array works fine, and is in a clean state.
I am having a RAID5 with a spare(total 4 disk).then the steps which lead me to a problem:
1. i was doing I/O on the array.
2. i pulled out a drive manually. So the spare drive took care of the failed one and started rebuilding. then
3. in the, mean time i pulled out the power plug of my NAS box.
4. After power up i saw my array was not active(by -D command option of mdadm). then
5. i executed: mdadm --assemble --scan /dev/md0 it gave me
I checked into the linux source and found that bd_claim is a function inside fs/block_dev.c and it failing due to which lock_rdev function (calling bd_claim in md.c) is failing and we are not able to start the array.I don't know why my RAID is not live after power on.
Plese help atleast can i save my data?
My problem is for the driver of controller ethernet jmicron jmc250. My version of Centos is 5.2, included in PBX In a Flash. I Have the original driver but these don't work and nic is not recognized.

I have an HTPC that was giving me insane amount of problems after 3 months of good use.
1x 250gig Samsung Drive (OS Drive)
3x 1TB Western Digital Caviar Green (Raid-5)
In 9.10, the raid was working fine. I decided to fresh install Ubuntu 10.04 and I can't seem to start the raid array. In Disk Utility, the array shows up but when I try to start it I get the error "Not enough components to start the array"
I've tried to assemble the array using mdadm and the following:
mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdd1
This returns the following error mdadm: failed to create /dev/md0
I have no idea what to do now, and unfortunately I don't have any backups
This is message I get when I try and start itmdadm: /dev/md0 assembled from 2 drives - not enough to start the arrayBelow is the information I've collected about any help on how I can get the raid back up and going to I can get the data off of it would be awesome

I have recently had a problem with my 10.04 server machine. It will not boot, it seems to be taking forever on the loading screen (normally headless server, but I connected monitor when I couldn't ssh), but that's not why I'm here.
Knowing that I do rsync backups every night at midnight of my machine I just bit the bullet and formatted my / partition. Reinstall went fine, I turned off automatic updates (I suspect an update caused the problem) But now I cannot mount my jmicron raid 1, which is where my rsync backup is (doh!).

how do i install a linux distro that doesnt natively support Intel fakeraid, using dmraid and a livedisk. the raid is already setup, its just that backtrack cant find it because it doesnt have the right software.
View 2 Replies View RelatedI have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care).
Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?
This _almost_ works. I just can't quite get it to honor the spaces.

1) Use INSSERV to start DMRAID
2) Use MKINITRD to create a new INITRD file which loads the DMRAID module.
Neither solution showed any detail of how to accomplish this, and which files to edit or what order I should use to tackle either. With the second solution, I have another SUSE 11.2 installation on another hard drive. Would it be ok to boot into that and create a new INITRD with DMRAID activated, or would it be better to break the RAID-set boot into one of the drives and create INITRD for that RAID 1 system, then recreate the RAID-set? The only issue I would see is that fstab, device mapper and grub would need the new pdc_xxxxxxxxxx value, which can be changed from the second installation.
My system is:
Asus M4A78T-E with fakeraid SB750 controller
AMD Black Edition - AMD Phenom II X4 3.4 GHz Processor
2 x Samsung 1TB drives
Suse 11.2
I have Windows XP on another hard drive purely for overclocking and syncing the 1TB drives, but I can't actually boot into the SUSE system until this issue is sorted out.

I powered down my file server this morning and started it back up a little while ago. One of the drive in a raid 6 array hung the system if it's inserted so after a little tomfoolery to identify the trouble drive. After removing it I finally have it booting but the raid array come up as inactive and all spares.I've "mdadm --examined" all the remaining drive in the drive in the raid6 array and the "events" are all the same, "2085124".When I assemble the array I get

I have a NETGEAR ReadyNAS NV+ with four 1TB drives in a RAID-5 array. This is our primary file storage. This has previously been backed up to a hardware RAID-0 array directly attached to our Windows server. The capacity of this backup array is no longer sufficient. So the plan was, take a bunch of 200GB to 320GB drives (And a 750) I had kicking around, chuck them in a couple of old SCSI drive enclosures I have collecting dust, attach them via IDA/SATA-to-USB adaptors to a USB hub, attach that to the server, create a JBOD array spanning the disks, and back up the NAS to that. Performance is not an issue as this is just to be used for backup, with the idea being as near to zero cost as possible (Spend so far = NZ$100�ish).
The first hurdle I struck was Windows not supporting Dynamic Disks on USB drives (Required to create a spanned volume). At first I resisted using another machine (i.e. a machine running Ubuntu) as I didn't want to dedicate a piece of hardware to backing up the NAS. I then decided it would be acceptable to do this via a VM, which is what I've done.So I have 10.04 running under VMWare Server 2.0.2 under Windows Server 2008 R2. The disks are all presented to the VM. I wasn't sure if I was going to end up creating the array under LVM or something else, but I noticed Disk Utility has an option to create an array, so I tried that. When I add two 250GB drives, the array size is 500GB. When I then add a 160GB drive, the array size drops to 480GB. Huh? If I keep adding disks (Regardless of order) the final array size comes out at 1.8 TB, as per the attached screenshot. Now with the following drives, I expected something more like:
160 + 250 + 250+ 750 + 250 +200 + 200 + 250 + 320 + 250 + 320 = 3.2TB
Am I missing something or making a false assumption somewhere?
I have an array called arrayini which stores numbers. I want to take log to the base 2 of each of the numbers in that array and put it in file called result. I've used the following code to do it.
Code:
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
echo "scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >result
It works fine but its taking pretty long to calculate since I've got about 230,000 items in the array. So I decided to store the result into an array hoping that it'd be faster. I tried the following code. arrayresult is where I try and store the result. The code doesn't work because of the second last line.
Code:
unset arrayresult
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
arrayresult[$i]="scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >FILE2
There is a syntax error clearly.

i ve run into problems while installing 11.3 x64. Installer stops at search for linux partitions... to solve it i ve had to go back to 11.2. Anyway, i have installed 11.3 on another hdd (3hdds in raid 5 had to be disconnected). When i go into partitoner (11.3) and device graph, i see two of three raid hdds ok with sda1, sda2.... but the third one is without any partitions./ if i do the same in 11.2 all three hdds are with all partitions in that graph. Anyone know the solution except not installing 11.3? .)
View 2 Replies View RelatedI have two Ubuntu 8.04 servers currently. I've purchased some 500 GB hard drives and a RAID cage just yesterday and plan to change my current servers to using RAID1 with the hard drives. Much like everyone else, I have the nVidia RAID built onto the motherboard that I plan to use. There are many how-to's out there on how to setup RAID using dmraid during the install process - but what would a person do if they are simply changing over to a RAId system? I installed dmraid a few days ago on the server. It seems that even though I have RAID shut off in the BIOS, it saw the one and only drive as a mirrored array. When I rebooted today, the server would not start; it had ERROR: degraded disks.. bla bla. Then Grub tried to start the partition based off the UUID of the drive (which was not changed) and it said "device or resource busy" and would not boot.
This problem was corrected by going into the BIOS and turning on RAID. When I rebooted, the nVidia RAID firmware started and said degraded. I went in there and deleted the so-called mirror keeping the data intact. Rebooted, disabled the RAID feature in the BIOS and then the server loaded normally with a message "NO RAID DISKS" - but at lest it did boot! So this leads me to believe that trying to turn on a RAID-1 array (just mirror between two disks) may be a challenge since I already have the system installed. I will be using Partimage to make an image of the current hard drive and then restore it to one of the new drives.
The next question is - is it a requirement that dmraid is even installed? While I understand that the nVidia RAID is fake-raid - if I go into the nVidia RAID controller and setup the mirroring between the two disks before I even restore the files to the new disk, will both drives be mirrored? However, I do think that I'd probably have to have dmraid installed to check the integrity of the array. So, I'm just a bit lost on this subject. I definitely do not want to start this server over from scratch - so curious to know if anyone has any guidance on simply making a mirrored array after the install procedure, what kind of Grub changes will be needed (because of the previous resource is busy message), and whether installing dmraid is even a requirement.
