Hi, I just got home from holidays... And when I tried to read my mails I noticed a drive og my raid 5 was marked as faulty. When reconstructing it another drive seemed to failed - but I think there was some trouble with my SCSI controller and another drive was marked as faulty... How can I try to recover the raid. The first and third disk should be fine. Here is my raidtab: raiddev /dev/md3 raid-level 5 nr-raid-disks 3 chunk-size 128 persistent-superblock 1 parity-algorithm left-symmetric device /dev/sda6 raid-disk 0 device /dev/sdb6 raid-disk 1 device /dev/sdc6 raid-disk 2 when trying to make a raidstart /dev/md3, I get the following output in /var/log/messages: 20:22:29 kopernikus kernel: [events: 000000eb] Nov 7 20:22:29 kopernikus kernel: [events: 000000ec] Nov 7 20:22:29 kopernikus kernel: [events: 000000ec] Nov 7 20:22:29 kopernikus kernel: md: autorun ...
