[5 years later] I have the same 3ware card. This past month, I've had a drive not come online a few times. This causes the normal need to remove/rebuild (logically, not physically) the RAID5 array. However.. ..twice in the last year, the troublesome drive comes online thinking IT is the RAID5 array and everyone else is missing-- split brain. Delete the ...

It depends on how the drive failed. 72GB 10k disks haven't been manufactured for years, so I'd suspect that your disks are at least 6 years old... possibly 9 years... You may have a mechanical problem with the disk. The server you're talking about is an HP ProLiant DL360 G5. They were sold from 2005-2008. Running RAID 0 is a calculated risk. Your data was ...

Here's my slightly generalized solution: sudo cp /tank2/test-text-file /tank1/test-text-file sudo zfs snapshot tank1@snapshot3 sudo sh -c 'zfs send -i tank1@snapshot2 tank1@snapshot3 | zfs receive -F tank2' sudo zfs rollback -r tank1@snapshot1 sudo sh -c 'zfs send -i tank2@snapshot1 tank2@snapshot3 | zfs receive -F tank1' sudo zpool scrub tank1; sudo zpool ...
