Package: mdadm
Version: 3.1.4-1+8efb9d1
Severity: important
Hi,
i don't now if this is the correct place to report the bug.
i used in a squezze system a raid1. Everything work ok for one year but than a hdd crashed. I removed the hdd (i don't know if i used mdadm /dev/md127 --remove /dev/sdx1).
i installed the new hdd and made a mdadm /dev/md127 --add /dev/sdc1. After that every thing looks ok:
nas:~# cat /proc/mdstat
Personalities : [raid1]
md127 : active raid1 sdb1[0] sdc1[2]
1953511936 blocks [2/1] [U_]
[=======>.............] recovery = 39.4% (769742848/1953511936) finish=202.1min speed=97610K/sec
unused devices: <none>
The recovering finished but the new hdd is a spare device instead of an active device:
nas:~# mdadm --detail /dev/md127
/dev/md127:
Raid Level : raid1
Raid Devices : 2
Total Devices : 2
Preferred Minor : 127
Persistence : Superblock is persistent
State : clean, degraded
Active Devices : 1
Working Devices : 2
Failed Devices : 0
Spare Devices : 1
Number Major Minor RaidDevice State
0 8 17 0 active sync /dev/sdb1
2 8 33 1 spare rebuilding /dev/sdc1
My question: Is this a bug or my fault??
More System infos follows below.
