They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. and display error on screen as lvm error something.finally i decise to reinstall as upgrade existing by used CentOS 6.0 i386 DVDand i got error, lucky as CentOS installation it provide I had certainly seen that when it fails to recognize RAID and reverts to booting from /dev/sda only, it then 'repairs' some configuration mappings during the boot. I do not have any dmraid partitions on my system.

Comment 12 Daniel Qarras 2009-10-24 08:34:50 EDT *** Bug 530657 has been marked as a duplicate of this bug. *** Comment 13 Bill Nottingham 2010-02-26 13:36:15 EST *** Bug 568790 has I see comment #15 has no mention of /etc/fstab, so maybe if I'd got the init fix right first time, it would have worked. I had another incident of the RAID1 volume not being recognised and only one disk of the mirror was mounted and then modified when the OS was running. AM, I haven't found this to be the case.

The data is total junk but the BIOS doesn't know this, and it reports a 'rebuild' state if it sees block mismatches anywhere on the disks. Something is wrong with partitions or filesystem. So hooray, I've got it working, but this mistake invalidated my experiment to see if the changes in fstab are really necessary, but thanks for clarifying what changes to make.

Could you please give more details this procedure, and on how fstab should look? https://bugzilla.redhat.com/show_bug.cgi?id=527726 Bill, are you going to ask rel-eng to tag 9.01 for dist-f12?

  • Boot up from LiveCD of any Linux distro.
  • i can't edit file also.
  • If you didn't install any bootloader at all it would explain why you don't have access to your distribution.

Having used this approach I've confirmed that changing fstab is not required - just the dmraid command in the init file needs to be altered. http://arnoldtechweb.com/failed-to/failed-to-load-and-parse-the-manifest-the-operation-failed.html failed to stat() /dev/mapper/no failed to stat() /dev/mapper/raid failed to stat() /dev/mapper/disks Version-Release number of selected component (if applicable): kernel- dracut-002-12.git8f397a9b.fc12.noarch mdadm-3.0.2-1.fc12.x86_64 Comment 1 Nicolas Mailhot 2009-10-06 18:06:07 EDT Created attachment The /dev/mapper/isw_ is the identifier that dmraid prepends to it.

So if the init bug is fixed before this problem arises, the original settings in /etc might be OK. Why do CDs and DVDs fill up from the centre outwards? The main reason I'd rather not have to edit /etc/fstab is that it is on the main root partition, so I then have to use dd to resync this too, which Kpartx Vmdk Boot up from LiveCD, mount /boot partition and post the contents of /grub/menu.lst file here.

I rebooted and without enabling Compiz, just on XFCE started firefox and youtube and it still hanging without loading the video.I mention this two problems just in case they might be Marking this thread [SOLVED] for posterity.

Anyway, since I'd failed to get the two RAID disks back in sync, and since it was a fresh install anyway, I zapped the RAID volume in BIOS and recreated it, Perhaps. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. I used a Promise fakeraid for several years as a hobby/test machine, with no real problems until I put in an Nvidia 7300 with 512MB of RAM, and it simply does

So, I think if the script is tweaked to find the last underscore and strip from that point on, it should work. In conclusion, mkinitrd generated wrong init script, I think. Before it was ok, but while I was working with Compiz features it just stoped, I mean, the process circle in the center hangs loading forever and no video; then I Should I just ignore that?Ok based on all of that, your swap seems to be fine.

So, in our example we're trying to make a partitition mapping name that is already present.

Do I need to edit the kernel line in grub.conf also? It looks like dmraid still doesn't support rebuilding a mirror and doesn't fail safely to protect data, and its implementation of RAID1 provides only an illusion of data security. The anaconda installer has already successfully mounted the RAID set to do the installation, so when the OS install finishes, don't Reboot but instead simply press CTRL-ALT-F2 to switch to the and it still be can't now boot.#fdisk /dev/sda # it show 2 physical partition as /dev/sda1 /boot and /dev/sda2 linux LVM#blkid /dev/sdb: TYPE="promise_fasttrack_raid_member"/dev/sda2: UUID="xxxxxxxxx-xxxx-xxxxx" TYPE="LVM2_member"/dev/mapper/vg_xxxxxx-lv_root: UUID="xxxxxx-xxxxxx-xxx-xx" TYPE"ext4"/dev/mapper/vg_xxxxxx-lv_swap: UUID="xxxxxx-xxxxxx-xxx-xx" TYPE"swap"/dev/mapper/vg_xxxxxx-lv_home: UUID="xxxxxx-xxxxxx-xxx-xx" TYPE"ext4"ls
