A few months ago you helped me re-do the MediaSonic Probox external drive enclosure. I replaced all four hard drives with WD RED 2T drives.
Bay 1 is mounted as /media/data2/, bay 2 is mounted as /media/data3, and bays 3 and 4 are a RAID1 (/dev/md0) mounted as /media/backup. Yesterday my dirvish backup reported rsync errors with /media/data2/ and /media/data3/. I sent one error report to the dirvish mail list (since they're both the same rsync input/output errors. No response yet. I've uploaded one dirvish error report (as temp.tmp) to <tinyurl.com/4fb96cku> because at 201 lines it's too large to include in this message. It will remain there for 5 days. The two drives are entered in /etc/fstab as: UUID=b50f1824-45ee-4623-adc7-ea737a88902b /media/data2 ext4 auto,users,rw 1 2 UUID=8b47d782-8e1c-46bb-b314-0c53d90d6fac /media/data3 ext4 auto,users,rw 1 2 and fdisk -l reports: The primary GPT table is corrupt, but the backup appears OK, so that will be used.

This all worked fine until Wednesday night. I think the fstab UUIDs are for the partitions /dev/sdi1 and /dev/sdj1 rather than for /dev/sdi and /dev/sdj. Could the WD RED drives have failed so quickly? Should I run fsck? If so, do I specify /dev/sdi and /dev/sdj or the *1 partitions? I need the data on these disks. Fortunately, I've added nothing to either on Tuesday so the backups through Tuesday are all okay. Rich
