Enviorment:
OS: Slackware 13.1
Server Type : HP ProLiant DL160 G6
Raid Card: Smart Array B110i SATA RAID
Disk : SATA 250G * 2
Raid Model: Raid 1
We have setted raid model (raid 1+0) in BIOS and when we finished install Slackware13.1 ,the OS can not recognise the raid disk(also two disk).Is there anybody can help me?Some solution or driver program or other infomation etc.My email is "feng.pan@continental-corporation.com".
Could any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:
Code:
root@127.0.0.1:/etc# mdadm --examine /dev/sdb2
/dev/sdb2:
Magic : a92b4efc
Version : 00.90.00
code....
Code:
mdadm --create --assume-clean --level=5 --raid-devices=4 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
As I don't want to ruin the maybe small chance I have left to rescue my data, I would like to hear the input of this wise community.
I have a VT6421 based raid controller. lspci shows this: 00:0a.0 RAID bus controller: VIA Technologies, Inc. VT6421 IDE RAID Controller (rev 50) The drivers that come with it appear to have been compiled against an old kernel (I'm guessing). When I try to load them I get invalid module format. dmesg shows this: viamraid: version magic '2.6.11-1.1369_FC4 686 REGPARM 4KSTACKS gcc-4.0' should be '2.6.27.7-smp SMP mod_unload Does anyone know of a way to get this to work? I found the source for this, but it appears to only support Fedora, Mandrak, and RedHat. I can't get it to compile or make a driver disk.
View 3 Replies View RelatedI am hoping there is somebody out there who might recall DPT hardware and be able to get it to work under Linux. DPT were bought up by Adaptec but made great SCSI cards. The PM3334UW is a true hardware raid device which I have been using in SOHO environment for the last 7 years or so with IBM Warp 4.52 (MCP2). The box, although legacy hardware is sound and I wish to keep it running but hoped to have an openSUSE option. Unfortunately I cannot find a driver for the SCSI RAID card. There are a good deal of posts concerning eata_dma.c and other eata based drivers as possibles but when I load the eata driver that is available when loading openSUSE 11.3 I am asked for parameters and I haven't a clue what these should be.
View 4 Replies View RelatedI just installed SUSE 11.2 as dual-boot with WinXP on an older system that has a 160GB PATA drive and a 500GB SATA RAID drive. I left about 80GB on the PATA drive unpartitioned to accommodate SUSE. During the initial installation attempt, SUSE was determined to install on the RAID drive instead of the PATA drive, so I disabled the SATA drivers in the BIOS to force the installation on the PATA drive. This was successful, but now there is no access to the RAID drive from SUSE because there is no driver and it is not mounted. I reactivated the SATA drivers in the BIOS and the RAID drive reappeared in WinXP with everything intact. The SATA drives now appear in SUSE under Hardware Information as "/dev/sdb" and "/dev/sdc" and the listed driver is "sata_sil".
So how do I get the RAID drivers installed in SUSE and then mount the drive so it can be browsed/modified from Dolphin? I would also like to be able to browse/change this drive from other computers on my home network through samba, just like with WinXP.
Currently I am attempting to install Centos 5.2 64bit onto a Supermicro X7DCL-3 motherboard based machine. The Raid recognizes the HDD that's been installed into it, however, the drivers for the raid are not included in the install. After contacting Supermicro I've been supplied with a driver package that should fix the problem.[URL]However, I am still having trouble using the package in order to find the HDD (The only HDD in the machine) that is on the raid.I think I'm doing something that's should be fairly simple, but am screwing it up pretty bad.

I know with Windows one has to load the RAID driver off the Intel driver CD, so guess that is the problem. But how do I do this in Fedora? Question: How do I get to select the Intel RAID driver in the install process? There does not seem to be any place to stop and make this selection. I tried selecting the Red Hat and Suze installs on the Intel configuration assistant but it then reboots and that is it. In Windows it would ask to insert the Intel driver CD but that does not happen. So I am stuck. I loaded Fedora some 3 year ago and like it but then it was not on a RAID setup. I created a VMWare install on my desktop and did the same install options and it works. So the DVD seems fine.
I have a system with RAid 0 with Windows 7. I want to load Ubuntu on a stand alone disk. I have two disks obviously for my raid o, two storage disks and an extra disk for ubuntu.

I have been running ubuntu on my laptop .
View 2 Replies View RelatedI have a raid5 on 10 disk, 750gb and it have worked fine with grub for a long time with ubuntu 10.04 lts. A couple of days ago I added a disk to the raid, growd it and then resized it.. BUT, I started the resize-process on a terminal on another computer, and after some time my girlfriend powered down that computer!
So the resize process cancelled in the middle and i couldn't acess any of the HDDs so I rebooted the server.
Now the problem, the system is not booting up, simple black with a blinking line. Used a rescue CD to boot it up, finised the resize-process and the raid seems to be working fine so I tried to boot normal again. Same problem. Rescue cd, updated grub, got several errors: error: unsupported RAID version: 0.91. I have tried to purge grub, grub-pc, grub commmon, removed /boot/grub and installed grub again. Same problem.
I have tried to erased mbr (# dd if=/dev/null of=/dev/sdX bs=446 count=1) on sda (ide disk, system), sdb (sata, new raid disk). Same problem. Removed and reinstalled ubuntu 11.04 and is now getting error: no such device: (hdd id). Again tried to reinstall grub on both sda and sdb, no luck. update-grub is still generating error about raid id 0.91 and is back on a blinking line on normal boot. When you'r resizeing a raid MDADM changed the ID from 0.90 to 0.91 to prevent something that happend happened. But since I have completed the resize-process MDADM have indeed changed the ID back to 0.90 on all disks.
I have also tried to follow a howto on a similar problem with a patch on [URL] But I cant compile, various error about dpkg. So my problem is, I cant get grub to work. It just gives me a blinking line and unsupported RAID version: 0.91.

I have installed Ubuntu on my m1530 since 8.04 and currently dual boot Win7 and 10.10. I would like to dual boot on my PC, but I have run into a problem. I am not a pro at Ubuntu, but this problem I can not solve by reading forums like I have in the past.
I realize this is a common problem, but I have noticed people having success.
I have a M4A87TD EVO MB with two Seagate drives in Raid 0. (The raid controller is a SB850 on that MB) I use the raid utility to create the raid drive that Windows7x64 uses. I have 2 partitions and 1 unused space. Partition 1 is Windows, partition 2 is for media, and the remaining unused space is for Ubuntu.
I am running ubuntu-10.10-desktop-amd64 off a Cruzer 16GB flash drive that was installed via Universal-USB-Installer-1.8.1.4.
My problem like so many others is that when I load into Ubuntu, gparted detects two separate hard drives instead of the raid. I read that this is because kpartx is not installed on 10.10. I then went in LiveCD mode and downloaded kpartx from Synaptic Manager. Gparted still reported two drives. I opened terminal and run a few commands with kpartx. I received an error. (Forgive me I didn't write it down, but I believe it said something about a communication error. I will try again later and see.)
Currently I am reflashing the Cruzer with a persistence of 4GB. I am not familiar with this process, but I understand that my LiveCD boot will save information I download to it. I decided to try this method because I was going to install kpartx and reboot to see if this made a difference.
I am looking for any suggestions on a different method or perhaps someone to tell me that the raid controller or some hardware isn't supported. I did install ubuntu-10.10-alternate-amd64 on my flash drive, but fail to get past detecting my CD-ROM drive since it's not plugged in. If this method is viable, I will plug it in. I also watched the ..... video were a guy creates Raid 0 with the alternated CD, but it wasn't a dual boot and didn't use a raid controller from a MB.
Fedora is having trouble identifying a raid partition, it sees them as separate drives. I got drivers from dell, but during a Fedora dvd install, it mentions nothing about a place to install extra drivers.
When it says it must "initialize" the drives, Fedora then breaks the dell bios raid. How to either install the dell drivers or make Fedora see the raid partition as one?

I have a raid array level 5 with metadata 1.2 made with mdadm. I put it on /etc/fstab to mount it on boot but it doesn't works because the raid is not detected on boot. I have a /etc/mdadm.conf like this:
Code:
ARRAY /dev/md0 level=raid5 num-devices=3 metadata=1.2 name=0 UUID=afdfe00e:0d18a5eb:29aa54f9:8b422ee0
Just another thing... After the command
Code:
mdadm --detail --scan >> /etc/mdadm.conf
The mdadm.conf is like this:
Code:
ARRAY /dev/md0 level=raid5 num-devices=3 metadata=1.02 name=0 UUID=afdfe00e:0d18a5eb:29aa54f9:8b422ee0
But I change manually the metadata version because the 1.02 give me a error. I don't know if it is a bug or what! Beside this. I have to put a line in /etc/rc.d/rc.local to assemble the array.
Code:
mdadm --assemble --scan --uuid=afdfe00e:0d18a5eb:29aa54f9:8b422ee0
And after that I already can mount it. Why the array is not detected on boot? Is because metadata type is prior to 1.00? Can I put the line I have on /etc/rc.d/rc.local to assemble the array in another file, that will be executed before /etc/fstab?
I'm somewhat stuck I fiddle with intel ss4200 NAS where I managed to install Slack 13.1 on some spare IDE HDD that was lying around (instead of that crappy 256 MB DOM). Anyway, everything works except one thing...
The setup is: 1x IDE HDD with Slackware on it. 4 x 1TB drives in RAID 5, which when mounted make 3 different logical drives. Everything works, /dev/md0 is created, pvc on top of it with 3 different drives. Well at least until I reboot. After reboot /dev/md0 is not automatically assembled and due to that - lvm stays inactive. Of course, I can make a script and put it in rc.local that will activate and mount what I want but I'm sure that there is one more elegant solution for that.
At the moment I need to issue: mdadm --assemble /dev/md0, vgchange -ay, mount -a and vgchange -an at shutdown. I checked parts concerning LVM in rc.S but I'm clueless. Kernel on the system is 2.6.36, mdadm - v2.6.9 and LVM version: 2.02.64
I'm building a NAS, based on the Intel SS4200. There are 4 drive bays in the machine for use with SATA disks, two of which I plan on filling now, the other two which I plan on filling later. The box also includes an IDE connector to which I will connect an 8GB Disk on Module onto which I will install Slackware. I wish to have all drives in the box show up as one contiguous volume. What partitioning/LVM/RAID configuration can I use which will allow me to:
1. Add a disk and transparently grow the available space of the volume?
2. Replace a disk with a larger disk and transparently grow the available space of the volume?
3. Lose a disk to hardware failure and replace it with a new one with no data loss?
If I use RAID 5, I'm pretty certain I can get numbers 1 and 3 above, but I'm not sure about number 2. The downside is that I'd have to start with 3 disks in the machine, and I'm unsure if adding a 4th disk whose size is larger than each of the 3 starting disks would lead to wasted space. For instance, if I start with three 1TB drives in RAID 5, and then add a 2TB 4th drive, would my available size go from 2TB to 3TB? Or from 2TB to 3.xTB?
Is it important in a RAID 5 setup to have all disks the same size? With LVM, I can certainly get number 1 above, but what about 2 and 3? I know you can use LVM to present many disks or partitions as one contiguous volume, but if I have two 1TB drives in one volume, and only have 300GB of data, then would the second drive remain empty until I broke the 1TB barrier? In this case, it's wasted space from the get go. I suppose another option would be to start with RAID 1 until I can afford a third disk.
When adding the new disk, could I switch to RAID 5 without data loss? I'm planning on maintaining a full mirror of the NAS on some USB disks as a backup, so if configuration changes to the NAS require wiping the disks and restoring from backup, it's not a total loss. However, it certainly makes me nervous to be in a state where only one copy of the data exists, so I'd rather find a solution where I can add and upgrade disks in the NAS without relying on the backup copies.

Right now, I have 7 raid arrays and mdadm starts at boot time. Until now, I used Mr. Goblin's script (http://connie.slackware.com/~mrgoblin/files/rc.mdadm) (thanks Mr Goblin!) to monitor my arrays.
The script is started at boot time from rc.local. I created a small script in /usr/bin that send the following command to rc.mdadm giving me the status of the arrays:
Code:
/etc/rc.d/rc.mdadm status
and it works fine, but this requires me probing the arrays manually by calling the script from the command line. I would like to automate probing every 10 minutes or whatever and if a fault has been detected, I get an email.

what do I have:2x 150GB drives (sda) on a raid card (raid 1)for the OS (slack 13.37)2x 2TB drives (sdb) on that same raid card (raid 1, too)2x 1.5TB drives (sdc,sdd) directly attached to MoBo2x 750GB drives (sde,sdf) attached to MoBo too.if i got about it the normal way, i'd create softRAID 1 out of the the 1.5TB and the 750GB drives and LVM all the data arrays (2TB+1.5TB+750GB) to get a unified disk.If I use btrfs will I be able to do the same? mean I have read how to create raid arrays with mkfs.btrfs and that some lvm capability is incorporated in the filesystem. but will it understand what I want it to do, if i just say

View 1 Replies View RelatedI am going to be using CentOs 5.4 for a home storage server. It will be RAID6 on 6 x 1TB drives. I plan on using an external enclosure which is connected via two SFF-8088 cables (4 drives a piece). I am looking to try and find a non-RAID HBA which would support this external enclosure and allow to use standard linux software raid.
If this is not an option, I'd consider using a hardware based raid card, but they are very expensive. The Adaptec 5085 is one option but is almost $800. If that is what I need for this thing to be solid then that is fine, I will spend the money but I am thinking that software raid may be the way to go.
