Hi!
I´ve got a problem with a software raid5.
PC runs debian sarge/sid/etch mix with 2.6.16 self built and mdadm mdadm
2.5.3.git200608202239-7.
1 of 6 SATA 400GB drives failes and I rebooted the PC.
After reboot RAID was resyncing.
But again the HD died and the PC rebooted again, I pulled off the bad HD
and now the RAID5 won´t resync again.
I built a 2.6.17 kernel and replaced mdadm to mdadm 2.5.4-1 and still
RAID5 won´t resync again:
cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid5] [raid4]
[raid6] [multipath] [faulty]
md0 : inactive sda1[0] sde1[5] sdd1[4] sdc1[3] sdb1[1]
