RAID5: recovery thread got woken up ...
Ho messo un sistema RAID5 con linux utilizzando 4 HD da 30GB IDE.
Un RAID5 senza spare-disk.
Vorrei sapere se i messaggi del kernel indicano qualche problema.
In particolare:
Jan 25 19:25:27 linux1 kernel: raid5: md0, not all disks are operational --
trying to recover array
Jan 25 19:25:28 linux1 kernel: md: recovery thread got woken up ...
Jan 25 19:25:28 linux1 kernel: md0: no spare disk to reconstruct array! --
continuing in degraded mode
Jan 25 19:25:28 linux1 kernel: md: recovery thread finished ...
Comunque in seguito ho il log completo:
