Recovery didn"t continue recovery after reboot

Recovery didn"t continue recovery after reboot

am 25.11.2009 05:14:19 von hank peng

I created a RAID5 array which consisted of 3 disks.
#mdadm -C /dev/md0 --metadata=1.1 --bitmap=internal -l5 -n3 /dev/sd{a,b,c}
Before initial recovery was done, I reboot my system. After system is
on, initial recovery didn't continue.
#cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5]
[raid4] [multipath]
md0 : active raid5 sda[0] sdc[3] sdb[1]
976772864 blocks super 1.1 level 5, 64k chunk, algorithm 2 [3/3] [UUU]

I removed '--bitmap' option and retest again, there was no problem and
recovery continued.

Is there something wrong? Any help will be appreciated!

It seems that there is problem when both '--metadata=3D1.1' and
'--bitmap=3Dinternal' optinons are used. Anyone on this list have seen
this case?
