Hi,
I have a problem with autodection of RAID 1 arrays.
I am running SuSE Linux 7.1 with an of-the-shelf kernel 2.4.3, where
aic7xxx and qlogicfc are loaded as modules via initrd.
I have 2 Raid 1 arrays configured:
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 16
persistent-superblock 1
device /dev/sdl1
raid-disk 0
device /dev/sdv1
raid-disk 1
raiddev /dev/md1
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 16
persistent-superblock 1
device /dev/sdm1
raid-disk 0
device /dev/sdw1
raid-disk 1
The partition type for all partitions is set to 0xfd.
The arrays work fine if started with raidstart /dev/md0 and raidstart
/dev/md1.
They are not autostarted, however, during system start. I tried both
compiling
md support into the kernel and as module.
Here is what I see in /var/log/boot.msg
....
<5>Trying to unmount old root ... okay
<4>Freeing unused kernel memory: 116k freed
<6>Adding Swap: 136512k swap-space (priority -1)
<6>md driver 0.90.0 MAX_MD_DEVS=256, MD_SB_DISKS=27
<4>md.c: sizeof(mdp_super_t) = 4096
<4>EXT2-fs: unable to read superblock
<4>EXT2-fs: unable to read superblock
(AW) here the kernel tries to mount /dev/md0 and /dev/md1
Kernel logging (ksyslog) stopped.
....
Can somebody help me?
Many thanks in advance ...
