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
