Looks like it started doing the initial synchronisation as normal, but
hid a read error on sdd1 which caused the array to fail. sdd1 is left
as faulty, and sdb1 is spare as the rebuild didn't complete. I'd
recommend testing sdd1 (SMART tests, read tests, write tests) before
trying to use it any further.
Cheers,
Robin
I think this unlikely because I did a full 4-pass badblocks
read/write-test on sdb, sdc and sdd before using them.
No bad blocks have been found.
smartctl -H shows PASSED on all 3 devices. However sdd and sdc have
Offline_Uncorrectable set to 1 while sdb has not. Is this a sign of disk
failure?
Best regards,
Markus
