Idee su come riparare il raid
Ciao a tutti :-)
Ho un raid 6 software su una debian stable.
Mi sono accorto poco tempo fa di:
mdadm --detail /dev/md0
/dev/md0:
Version : 00.90.03
Creation Time : Wed Jan 30 17:42:24 2008
Raid Level : raid6
Array Size : 3418705472 (3260.33 GiB 3500.75 GB)

Number Major Minor RaidDevice State
0 8 64 0 active sync /dev/sde
1 8 112 1 active sync /dev/sdh
2 8 32 2 active sync /dev/sdc
3 8 16 3 active sync /dev/sdb
4 8 80 4 active sync /dev/sdf
5 8 128 5 active sync /dev/sdi
9 8 0 6 spare rebuilding /dev/sda
7 8 96 7 active sync /dev/sdg
10 8 48 8 spare rebuilding /dev/sdd
dopo un po' si blocca tutto perche' /dev/sdh ha problemi, dmesg dice:
ata9.00: exception Emask 0x10 SAct 0x0 SErr 0x90000 action 0x2 frozen
ata9.00: cmd c8/00:e0:20:1a:3d/00:00:00:00:00/e1 tag 0 cdb 0x0 data 114688 in

DPO or FUA
ata9.00: exception Emask 0x10 SAct 0x0 SErr 0x90000 action 0x2 frozen
In sostanza ho: /dev/sdh che funziona male (quindi va sostituito) ma sia sda e
sdd sono in spare rebuilding
Se sostituisco sdh, il raid non dovrebbe piu' partire, no? perche' non
riuscirebbe ad utilizzare i dischi di spare.
Quindi come potrei risolvere?
Grazie!
Pol
