Subject: drive is a spare, but I want to make it active - how?
Date: Thu, 10 Aug 2006 13:48:55 +0200 [thread overview]
Message-ID: <44DB1D27.4010508@wpkg.org> (raw)
I created RAID-10 on 4 drives, and I'm testing it a bit.
I removed one drive, and then added it again.
mdadm --detail says:
Version : 01.00.03
Creation Time : Thu Aug 10 10:15:18 2006
Raid Level : raid10
Array Size : 779264640 (743.16 GiB 797.97 GB)
Device Size : 779264640 (371.58 GiB 398.98 GB)
Raid Devices : 4
Total Devices : 4
Preferred Minor : 11
Persistence : Superblock is persistent
Update Time : Thu Aug 10 13:14:44 2006
State : active, degraded, resyncing
Active Devices : 3
Working Devices : 4
Failed Devices : 0
Spare Devices : 1
Layout : near=2, far=1
Chunk Size : 64K
Rebuild Status : 39% complete
Name : 11
UUID : 3f0bf25c:614339d1:31c006be:e823b74d
Events : 13
Number Major Minor RaidDevice State
0 0 0 0 removed
1 8 18 1 active sync /dev/sdb2
2 8 34 2 active sync /dev/sdc2
3 8 50 3 active sync /dev/sdd2
4 8 2 - spare /dev/sda2
So, I have 4 working devices, which include 3 active devices and one
spare device.
As I remember, with RAID-1, when I added a spare with "mdadm /dev/mdX -a
/dev/sdY", I would see a message "hot added /dev/sdY", and state "spare
rebuilding" in "mdadm --detail" output.
Right now I don't see the spare is being rebuilt? Spare HDD LED doesn't
blink either, so it would indicate that it's doing nothing.
Why? Is it because the rebuild status is not complete?
