I have tried dd from a LIve Ubuntu disk, and now clonezilla-live to
create an identical image of a RAID-1 array with 2 mirrored drives, onto
a single SATA drive. However, both methods still cant seem to boot and
have trouble finding the logical volumes? Maybe I am not using Clonzilla
correclty, or its simply not possible. I would be so grateful if someone
could let me know if this is possible with clonezilla.
Below is what I tried from the Ubuntu Live disk but I also tried with
Clonezilla following the onscreen prompts.
Niether method seems to be able to find the local volume/groups at boot.
I have a CentOS 5.4 server with a 3ware 9500 SATA Raid card with 2x320
gb drives as RAID-1.
Setup included logical volumes, physical drive is seen as /dev/sda
This is what fdisk sees:
r...@gateway:~# fdisk -l
Disk /dev/sda: 319.9 GB, 319988695040 bytes
255 heads, 63 sectors/track, 38903 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 38903 312383925 8e Linux LVM
What I am trying to do is remove the 3ware RAID and run the system off a
single 320gb SATA drive which is attached.
So I plugged in a basic SiL Raid card with a single 320gb drive
Booted Ubuntu Live and old RAID-1 array on the 3ware card is seen as
/dev./sdb
The new, single 320gb drive seen as /dev/sda
From a terminal I ran
dd if=/dev/sdb of=/dev/sda
copy finished with no errors
Unplugged the 2x320gb drives on the 3ware controller
Booted system, grub loaded (giving me so much false hope)
then, the boot failed at...
Volume group "VolGroup00" not found
unable to access resume device (/dev/VolGroup00/LogVol04)
Mount: could not find filesystem '/devroot'
So the problem seems to be that the LVM's are not seen?
Is there another, or better way to make a compelte, and working mirror
of a drive containing logical volumes?
When I reboot back in the working system, with the RAID on the 3ware
card, this is what both drives now look like to fdisk.
r...@gateway:~# fdisk -l
Disk /dev/sda: 319.9 GB, 319988695040 bytes (3ware working RAID)
255 heads, 63 sectors/track, 38903 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 38903 312383925 8e Linux LVM
Disk /dev/sdb: 320.0 GB, 320072933376 bytes (Non-booting single drive on
Sil card)
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 13 104391 83 Linux
/dev/sdb2 14 38903 312383925 8e Linux LVM
