But I wouldn't get rid of the cheap drives. They may lack features needed for best use in a raid array, but they are fine for solo duties. I have some similarly annoying Seagate drives. I use them one-by-one for off-site rotating backups. > for x in /dev/sd[bce] ; do parted $x unit s print ; done > Model: ATA WDC WD20EARS-00M (scsi) > Disk /dev/sdb: 3907029168s > Sector size (logical/physical): 512B/512B > Partition Table: gpt > > Number Start End Size File system Name Flags > 1 34s 3907029118s 3907029085s raid > > Model: ATA WDC WD20EARS-00M (scsi) > Disk /dev/sdc: 3907029168s > Sector size (logical/physical): 512B/512B > Partition Table: gpt > > Number Start End Size File system Name Flags > 1 2048s 3907028991s 3907026944s > > Model: ATA WDC WD20EARS-00M (scsi) > Disk /dev/sde: 3907029168s > Sector size (logical/physical): 512B/512B > Partition Table: gpt > > Number Start End Size File system Name Flags > 1 34s 3907029118s 3907029085s raid >> >> The partition structure on /dev/sdc is causing the array to be too short >> for the filesystem.

For this, repartition /dev/sdc to start at 34 and end at 3907029118. This makes it match sdb and sde. Then re-create the array, open luks, and do "fsck -n" and show the results. >> ps.
