FWIW the value is at 1 for the 4 disks in the raid anyway. The SCSI disk has value 8, which is probably irrelevant. For completeness' sake: mdadm version: mdadm - v2.6.4 - 19th October 2007 raid setup command: mdadm --create /dev/md0 --verbose --metadata=1.0 --homehost=jesus -n4 -c1024 -l5 --bitmap=internal --name tb-storage -ayes /dev/sd[bcde] cryptsetup command: cryptsetup luksFormat /dev/md0 --align-payload=2048 Any other suggestions on any of the issues?
