Subject: RAID5 rebuild difficulties
Date: Wed, 20 Aug 2003 14:53:38 +0200 [thread overview]
Message-ID: <200308201453.38427.ebenard@free.fr> (raw)
Hi,
I'm having some troubles to rebuild a software RAID5 after several power
failures.
Does anyone have an idea on how I could resync superblock of 4 partitions in
order to rebuild the raid without loosing data ?
Many thanks and best regards
Eric
