I have a few problems regarding my software RAID0 solution. I have two
disks, hdb and hdd, on a raid0 array. Everything was working fine until I
upgraded my kernel (from 2.2.12 to 2.2.16). Yes, support for RAID is
compiled in the kernel. On bootup, I get :
EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended
EXT2-fs error (device ide1(22,1)): ext2_check_blocks_bitmap: Wrong free
blocks count for group 888, stored = 7613, counted = 7901
EXT2-fs error (device ide1(22,1)): ext2_check_blocks_bitmap: Wrong free
blocks count in super block, stored = 1672643, counted = 1672931
Oops ! md0 not running, giving up !
Bad md_map in ll_rw_block
EXT2-fs: unable to read superblock
Oops ! md0 not running, giving up !
and I am dumped to a maintenance shell. When I try and manually start the
raid, I get the error
[root@****** /etc]# /sbin/mkraid /dev/md0
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/hdb, 12714912kB, raid superblock at 12714816kB
/dev/hdb appears to contain an ext2 filesystem -- use -f to override
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
The above is with persistent-superblock set to one. When I set it to 0, I
get the following :
[root@***** /etc]# /sbin/mkraid /dev/md0
handling MD device /dev/md0
analyzing super-block
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
The contents of my /etc/raidtab :
raiddev /dev/md0
raid-level 0
nr-raid-disks 2
persistent-superblock 1
chunk-size 4
device /dev/hdb
raid-disk 0
device /dev/hdd
raid-disk 1
I am using mkraid version 0.90.0
Sorry for the long message, but if you can help at all, I would appreciate it.
Thanks,
Jordan
