I've got a recovery disk to enable me to gain access to the raid array. If I have, what should I be looking for and how do I recover my system, please? I'm still looking for a fix to my problem! I've found a pair of recovery floppies (Yard) and managed to mount my md0 on /mnt. Mdstat showed that /dev/sdc1 had been removed from the array. I then tried raidhotadding /dev/sdc1 and the array started reconstructing. The disk previously marked as failed (sdc1) was added to the array, but now I've got _two_other_ (previously good) disks marked as failed - and with two out of four disks failed, I still can't recover the array! This time the errors reported were: raid5: md0 unrecoverable I/O error for block (various numbers). Too many read errors, stopping reconstruction. raid5 resync aborted. I'm getting really pissed off with raid5 - it looks like I'm going to have to do yet another complete reinstallation of the system! I'm convinced that it's not the disks - I can format and check them for bad blocks with no reported errors. The SCSI card appears to be OK (It's a SYM5C810A) and the cable's an ex IBM one - so that should be OK. Where do I go next - anyone?
