OpenSUSE Install :: 11.1 Machine Won't Boot To RAID1 Md0?

Mar 2, 2010

I cleverly built a machine with two drives mirrored, boot partition on the mirror. It crashed some time when I was not present, and was apparently writing to disk at the time, for since, it will not boot. I get error messages to the effect that there is no boot partition. At this point I am not particularly concerned to try to rebuild this array, though I have read a hell of a lot on the boards about trying that (and am daunted - everyone assumes you can boot the machine with the bad array). Instead, I am wondering is it possible to build a simple machine on a third disk, then "look" at the disks in the former (?) array, and/or potentially rebuild it?

OpenSUSE Install :: Unable To Boot From A Faulty RAID1?

Jul 14, 2010

opensuse 11.2 64 bits installed in a RAID1 software array. Everything worked smooth during installation, the system boots, the mdx partitions are in their places, did the upgrades, configured the way i wanted, booted several times... all ok. Then i wanted to test the RAID and since its RAID1 i just disconnected 1 drive and started the computer. All what i got is

GRUB loading stage 1.5
GRUB loading, please wait...
Error 21

Connect the drive back and the system works ok.

Disconnect the other drive, then i got
GRUB loading stage 1.5
GRUB loading, pleas wait...
(hd1,0)/message: file not found
and a simple boot menu (in character mode) shows up with the 2 options SUSE LINUX and Failsafe -- SUSE LINUX (no version number)

OpenSUSE Install :: Can't Boot Live Kde Cd Or Usb On Machine With Radeon 6870

Jul 19, 2011

As per the thread title, tried both 32 and 64-bit isos, also re-downloaded the isos in case of a problem with them

Fails to enter runlevel 5 (and start kdm), I've tried the usual nomodeset, setting no_kms_in_initrd isn't much help as mkinitrd fails after setting it

Here's the gist of the errormsgs:

Code:
(==) Using config directory: "/etc/X11/xorg.conf.d"
(EE) Failed to load module "fglrx" (module does not exist" (0)
(II) [KMS] drm report modesetting isn't supported
(EE) RADEON(0): Chipset: "AMD Radeon HD 6800 Series" (ChipID = 0x6738) requires kms Some things I've tried:

Blacklisting fglrx doesn't work with vi as it tells me 50-blacklist.conf is read-only even when I use the ! override read-only switch

Tried specifying both the radeon and radeonhd and even vesa drivers in /etc/X11/xorg.conf.d/50-device.conf when trying off a usb pen drive created with imagewriter

As mentioned earlier. tried nomodeset and no_kms_in_initrd to yes

It's a pain as I have tumbleweed on the machine and prior to putting the radeon card in it I would use a live usb drive to backup the system prior to updating, when I had an nividia card in the machine live usb and live cd would both boot no problem so it pretty much has to be something about the way it's handling the radeon card (like trying to load the non-existent fglrx driver regardless of what I do to try stopping that maybe?)

Don't know what else to try though and if I can't get it booting off a live opensuse I can see myself putting another os on it somewhere just for backing up the system before any updates

OpenSUSE Install :: Suse 11.2 Don't Boot On Server Machine Dell R710

May 26, 2010

for any reason after installation system hangs up and nothing happens, i�m newbie about linux, maybe the problem is the RAID 1 configuration of the disks. The machine is a R710 Server:

OpenSUSE Install :: 11.3 Installation With RAID1 On Two Disks?

Dec 14, 2010

I fail to install OpenSuse 11.3 with Raid-1. What I do: Partitioning -> Expert. sda1 type RAID do not format / mount, sda2 /(root) type RAID do not format / mount, sda3 /home type RAID do not format/mount. Clone disk to sdb. Raid -> add md126p1 type swap mount to swap, add->md126p2 type etx4 mount to /(root), md126p3 type ext4 mount to /home. Bootloader: GRUB, boot from MBR enabled, boot from / disabled. After installation the system does not boot and grub reports error that the specified filesystem can not be found.

Ubuntu Installation :: Fresh 10.04 Raid1 Install Will Not Boot W/o Manual Grub Input?

May 3, 2011

Followed steps 2-5 and purged/reinstalled grub now it boots as it should, NO idea where it was messed up.[URL].. I had 9.10 running in raid1 and upgraded my hardware (cpu, mb, memory etc) and wanted to do a fresh install of 10.04 to get updated. After following the various guides online such as [URL]...It begins to load grub and drops to a "grub> " shell. Which I have to do the following to get it to boot.

Code:
set root=(md1)
linux /vmlinuz root=/dev/md1 ro
initrd /initrd.img
boot

Then it boots up normally and I can use it like any other desktop. I've been over my grub.cfg and /etc/defaut/grub files and cannot find the issue. At this point I'm wondering if the fact it's a raid1 setup is keeping grub from finding it's files.

OpenSUSE Install :: Mdadm - Change Spare To Active In RAID1 Array?

Aug 7, 2011

I'm convinced that mdadm is going to be the death of me. I've wasted numerous hours on this so far without luck.

OpenSuse 11.4 on an old Supermicro box, creating a software RAID1 array across 2 x IDE 500GB disks. Creating /dev/md0 as a 250MB partition across /dev/sda1 and /dev/sdd1 for /boot, another 465GB partition across /dev/sda2 and /dev/sdd2 as an LVM partition to hold volumes for the various other OS filesystems. After the initial installation and configuration there were a series of mishaps with faulty IDE cables that had drives failing to show up at boot. Somehow, /dev/sdd2 got configured to array /dev/md1 as a spare drive. And nothing I've done so far gets it to show up as an active drive.

The obvious step of failing the partition, removing it, then adding (or re-adding) will bring it back as a spare. I've tried roughly a dozen different permutations of those same steps. The latest was to 'dd if=/dev/zero of=/dev/sdd2' to clear the partition. Thought this might be the trick - after the zero, mdadm -E /dev/sdd2 reported 'no superblock' and no md1 configuration.

So 'mdadm --add /dev/md1 /dev/sdd2' and it still comes back as a spare. Here is mdadm -D /dev/md1

/dev/md1:
Version : 1.0
Creation Time : Sat Jul 9 10:26:01 2011
Raid Level : raid1
Array Size : 488119160 (465.51 GiB 499.83 GB)
code....

I can't stop this array, the OS is running from there. I can't easily boot from CD to repair, all IDE ports have disks attached.

Does anyone have an incantation to promote a spare to active?

Fedora :: F13 - Boot With RAID1 / LVM / Dracut?

Dec 10, 2010

I am trying to boot my F13 server that has 3 partitions (sda2,sdb2,sdc2) configured as RAID1 (md0), vg00 is on md0 and / is on vg00/lvol00 and boot is on /dev/sda1, sda3,sdb3 and sdc3 contain other non-OS data and I get the following errors
dracut scanning devices sda3,sdb3,sdc3 for LVM logical volumes vg00/lvol00 vg00/lvol01
.
dracut: Volume group "vg00" not found
dracut: Skipping volume group vg00
dracut: Autoassembling MD Raid
No root device round
and then everything stops
If I go in with rdshell and type in -

[Code]...

Ok I managed to solve it. When I originally installed F13 I had 2 partitions in md0 and later on I added /dev/sdc2 to make it a 3 partition Raid 1 array. My thinking was seeing that I had the extra space it wouldn't hurt to use it as another mirror. One month later after I booted the server I have found out it did hurt. I removed the 3rd partition and now it's fine again. I wonder though if it would be possible though to use that 3rd partition.

Server :: Best Way To RAID1 The Boot Drive?

May 17, 2010

I am self teaching everything I need to develop a home-based web server (linux/apache/php/mysql/html/css/etc...) It's quite an undertaking, but not beyond my abilities. I thought this question could have gone in either the linux - software or linux - hardware forum, and certainly not in the n00b section, but I figured it's best be put in the linux - server forum, since that's what this is related to.

I have been looking into the software and hardware RAID solutions for linux because I wanted to make sure that the boot drive of the web server I set up is mirrored with transparent disk fail/replace/recovery. I mean, setting up a boot drive for RAID1 sounded perfectly logical to me, and why wouldn't it to anybody else? So, since I knew RAID controllers were expensive, I looked into the native software RAID support in linux. My findings have revealed an issue with software raiding a boot drive in not only linux but windows as well. Apparently, if the primary drive fails (not the mirror), you have no other option but to power down the system to properly replace the failed disk, reboot, play some config crap, resync the drive, do some more config crap, reboot again, and -hopefully- it'll be ok. Well, that procedure is simply out of the question since the idea behind RAID is to transparently proceed as if nothing happened.

I'd like to know if it's even possible to RAID1 the boot drive for transparent and automatic fail/hot-swap/recover WITHOUT rebooting the system and with no intervention on my part other then replacing the drive whether it be a software raid or hardware raid solution. Eventually, what I'd like to do for a drive configuration is have 3 RAID volumes on the server configured like so:

RAID volume 1 = boot drive w/ webserver installed
RAID volume 2 = database files
RAID volume 3 = flatfile storage
Each raid volume will be a RAID1 of a 1TB drive (total = 6 x 1TB drives)

I've seen a lot of people having failure issues with the software RAID in these forums. Is this more common than not? I'm certainly not opposed to buying a hardware RAID solution as long as they're reliable and provide transparent/automatic recovery. So what's the best way to RAID1 the boot drive for transparent/automatic failover?

Ubuntu Servers :: Boot From Raid1 (mdadm) + Lvm

Aug 11, 2010

intending to set up an all-in-one server, i threw in the ubuntu server 10.04 (amd64) cd. during the text-install, i set up the device-topology below, and it worked.

[Code]....

then i tested my raid by hot-pulling off the sda wire (ouch). worked fine, system still worked, and it also managed rebooting from the left sdb (which of course showed up being sda, lacking the first drive). now i am trying to recover this pre-crash state. adding the first disk (showing up as sdb), i can add it to md0 and let it start syncronizing for 2 hours. but... i can?t boot anymore with the recovered first disk being sda...

at first, booting got stuck in an initrd-prompt after complaining it couldn?t find my sys-logical volume. after a lot of trial and error i don?t even get any complaints, just a black screen which would let me wait for a boot for weeks... so, my system does not boot from my first disk, whether i plug in the second or not. my second disk still boots. my last attempt to get booting fine again has been: zero sda?s first and last gigabyte to kill any ids duplicate sdb?s first cylinder to sda to make it bootable reinitialize sdb?s part.table using command o in fdisk for a new disk-id recreate sda1 partition add sda1 to md0

Server :: Raid1 On Debian Won't Boot After Growing?

Apr 21, 2010

I installed a raid1 on a debian lenny box with only 1 drive "--raid-devices=1" because I didn't have the other drive yet. When I got the other drive, I used "mdadm --grow /dev/md0 --raid-devices=2" and "mdadm --manage /dev/md0 --add /dev/sdb1" The original drive is sda1. I watched /proc/mdstat until it was completely synced, and after a reboot, the system will not reassamble the raid. It fails with "mdadm: no devices found for /dev/md0" This is where root is, therefore, I get nowhere. From a rescue cd I can disable the other drive and shrink back down to 1 device and it boots fine.

Ubuntu :: Raid1 Array Won't Start On Boot

Jan 2, 2011

I created a raid1 disk with Disk Utilities on with Karmic, then upgraded my system to Lucid then Maverick. 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.

Installation :: Install Ubuntu On XP Machine That Won't Boot?

Feb 1, 2011

I haven't used Linux/Ubuntu before but I feel the time has come!

My parents Windows XP Dell machine won't boot (says it's corrupt, stops itself before windows loads). It's been dragged down by virus/malmare lately and is fairly sick.

I'm no Windows expert and can't seem to fix it, but I thought if I install Ubuntu for them they'd be alright, get them away from Windows for good�.but can anyone tell me in very simple terms the procedure I need to go through to install Ubuntu.

I can download Ubuntu now on my machine and burn it onto a CD or put it on a USB stick.

I'm especially keen to know how to ensure I retrieve all their data (mostly photos...they do have back up system but I've no guarantee it's actually be working lately).

General :: Mirror The Boot Partition On Existing Raid1?

Feb 26, 2011

I have a raid1 setup on a machine. Recently it died and I thought one of the drives had failed as it was shooting errors. So I tried unplugging that drive get it to boot off the mirror but it seems the techs forgot to mirror the boot device so the 2nd drive can't boot on its own. After a while it was realized that the sata cable was in fact bad and replaced so now its working again.

However, this occurrence showed a flaw in the setup where the RAID1 isn't working as its supposed to. I would like to correct this. Can I somehow mirror the boot partition so the 2nd drive will boot independent? I'm not sure how I would go about this. This is a CentOS 5 installation.

OpenSUSE Install :: Multiple Machine Flash Drive Install Planning?

Jun 18, 2010

I have two different laptops that I would like to make bootable flash drive installs for, but would then like to have at least /home on a common removable storage (either a big flash drive or USB or ethernet hard drive) to share between the two laptops (I'll only be using one laptop as a Linux box at a time). One laptop (Dell Latitude D410) is only 32 bit capable (Pentium M - I think there's a 64 bit Core 2 CPU available for the socket 479, but I don't know if the BIOS / mobo will support it). If I'm going back and forth between 32 and 64 bits, can I share /home? What else can I share - /usr or anything else?

OpenSUSE Install :: Upgraded Machine Boots Slower Than New Install?

Mar 19, 2010

recently I have installed a brand new machine with 11.2. Machine boots so incredibly fast so I decided to upgraded another older machine from 11.1 to 11.2. Upgrade went fine but old machine boots significantly slower. On new I see message "doing fastboot" and few seconds later KDE starts loading. Amazing. On old I just experience regular boot, speed is comparable to old 11.1.What am I missing after upgrade? Same kernel, almost same set of services. Both machines are pretty regular PCs/x86_64, however old one have faster/better hardware (more cores, more GHz, more RAM, 2 disks in software raid-0).

OpenSUSE Install :: Installing Machine With No DVD Drive

Jan 7, 2010

I'm trying to install on a machine that has a CD drive but no DVD (and is currently running 10.3). Following the procedure here I created a filesystem on the server and copied the DVD ISO to that. I boot with the network install CD and in the boot options I put in
install=hd:/dev/sda7/openSUSE-11.2-i586.iso
But then I get a red error diag saying
Could not find the openSUSE respository
Activating manual setup program

I go into the manual setup program, select hard disk, sda7, the iso file appears in the "Enter the source directory." dialog so I click OK. It does the "Loading the installation system" (or something, it's quick) and then errors with "No repository found". I have also tried sharing the iso file from a windows server and using network SMB but that didn't work. Tried mounting the install DVD (that I have used successfully before) on the windows machine, sharing it, and point the manual SMB install at that. Everything gives me "No repository found." I could use the Network CD to do an Internet install, but that seems unnecessarily slow and wasteful of bandwidth when I've already downloaded the DVD iso.

Debian Hardware :: Fresh Jessie Install - Machine Doesn't Boot With PCIe WiFi

Fedora Hardware :: Software RAID1 /boot Volume Doesn't Mount Automatically At System Startup

Feb 7, 2010

My software RAID setup is as follows.

/dev/md0 (made from sda1 and sdb1) RAID1 /boot partition
/dev/md1 (made from sda2, sdb2, and sdc2) RAID5 / partition

Earlier on I had some trouble with my sda drive, it dropped itself from both arrays, screwing up the mirroring of my two raid partitions participating in the /boot partition. I eventually got everything sorted out and back in sync. (I also have grub installed to MBR on both sda and sdb). Things are working fine regarding that, but since then I've had this issue:

During boot up, I'll get an error message that it could not mount my /boot partition (when fstab is set to either /dev/md0 or the UUID). It claims c9ab814c-47ea-492d-a3be-1eaa88d53477 does not exist!

My fstab:

Code:

[mark@mark-box ~]$ cat /etc/fstab
#
# /etc/fstab
# Created by anaconda on Wed Jan 20 16:34:41 2010

[code]....

As far as I know, it isn't neccessary for /boot to be mounted always, correct? Although, as I understand, I need to have it mounted whenever making kernel changes correct?
