Hello everyone,
I've got a strange SparesMissing event on one of my raid1 arrays.
mdadm --detail /dev/md2 says all ok, but I get this message by mdadm
monitor every day:
A SparesMissing event had been detected on md device /dev/md2.
Faithfully yours, etc.
P.S. The /proc/mdstat file currently contains the following:
Personalities : [raid1]
md2 : active raid1 sda3[0] sdc3[2](S) sdb3[1]
474714048 blocks [2/2] [UU]
[...]
root@MCI03:~# mdadm --detail /dev/md2
/dev/md2:
Version : 0.90
Creation Time : Fri May 28 14:54:26 2010
Raid Level : raid1
Array Size : 474714048 (452.72 GiB 486.11 GB)
Used Dev Size : 474714048 (452.72 GiB 486.11 GB)
Raid Devices : 2
Total Devices : 3
Preferred Minor : 2
Persistence : Superblock is persistent
Update Time : Wed Aug 11 08:52:13 2010
State : clean
Active Devices : 2
Working Devices : 3
Failed Devices : 0
Spare Devices : 1
UUID : 7aa24776:9d6e8d24:54307b3d:1949437b (local to host MCI03)
Events : 0.985979
Number Major Minor RaidDevice State
0 8 3 0 active sync /dev/sda3
1 8 19 1 active sync /dev/sdb3
2 8 35 - spare /dev/sdc3
This makes me wonder, too:
root@MCI03:~# mdadm --examine --scan
ARRAY /dev/md0 UUID=304f5f2a:fbc8082b:54307b3d:1949437b
spares=1
ARRAY /dev/md1 UUID=b263f9c1:5c680152:54307b3d:1949437b
spares=1
ARRAY /dev/md2 UUID=7aa24776:9d6e8d24:54307b3d:1949437b
spares=2
Why spares=2 for md2? It was created during Debian system install with
spares=1.
root@MCI03:~# mdadm -V
mdadm - v3.0.3 - 22nd October 2009
root@MCI03:~# uname -r
2.6.32preemptive
What's wrong here?
Thanks for any comments!
Best regards, Tobi
