Hello, cooker.
linux 2.4.17
raidtools-0.90-11mdk
raiddev /dev/md2
raid-level 5
nr-raid-disks 4
nr-spare-disks 0
persistent-superblock 0
chunk-size 4
parity-algorithm left-symmetric
device /dev/loop0
raid-disk 0
device /dev/loop1
raid-disk 1
device /dev/loop2
raid-disk 2
device /dev/loop3
raid-disk 3
after creating test raid5 array on loop devices, i run mkraid,
raidstop, raidstart.
[root@backupsrv /home]# cat /proc/mdstat
Personalities : [raid0] [raid5]
read_ahead 1024 sectors
md2 : active raid5 [dev 07:02][2] [dev 07:01][1] [dev 07:00][0]
307008 blocks level 5, 4k chunk, algorithm 2 [4/3] [UUU_]
with persistent-superblock = 0, i got various errors while try to
start raid arrays (loop devices, hard disks): arrays starts without
one disk, arrays does not start: it can't read superblock on disk0,
arrays does not start: SIGIO failed...
with persistent-superblock = 1 works more fine.
