Hi,
According to this :
http://drbl.sourceforge.net/faq/fine-print.php?path=./2_System/65_Clonezilla_support_RAID.faq
Clonezilla does not support software RAID, but can someone provide some
more details why not ?
If I look at my software RAID 1 setup, I can still see the separate
device file descriptors :
# ls -la /dev/sda*
brw-rw---- 1 root disk 8, 0 2009-08-08 00:54 /dev/sda
brw-rw---- 1 root disk 8, 1 2009-08-08 00:54 /dev/sda1
brw-rw---- 1 root disk 8, 2 2009-08-08 00:54 /dev/sda2
brw-rw---- 1 root disk 8, 3 2009-08-08 00:54 /dev/sda3
brw-rw---- 1 root disk 8, 4 2009-08-08 00:54 /dev/sda4
# cat /proc/mdstat
Personalities : [raid1]
md2 : active raid1 sda4[0] sdb4[1]
437506112 blocks [2/2] [UU]
md1 : active raid1 sda3[0] sdb3[1]
48829440 blocks [2/2] [UU]
md0 : active raid1 sda1[0] sdb1[1]
96256 blocks [2/2] [UU]
unused devices: <none>
What would go wrong if I would use clonezilla to make a clone of one of
the two disks,
by pointing it to the /dev/sda (etc.), and restore it on another (new) disk,
and let the software RAID 1 sync with yet another disk later on ?
# time dd if=/dev/sda1 of=sda1-test count=100 bs=16k

# diff md0-test sda1-test
#
.... no difference between those two test files
TIA,
A.
