July 28, 201411 yr So basically I'm in the process of rebuilding disk2 and noticed that the rebuild is quite slow, 10MB/s, log reveals another disk is in error...not good Multiple lines of the following: kernel: md: disk6 read error, sector=58580264 Disk6 is sdb from the main unRAID interface, and here's the smart report attached as per smartctl -a /dev/sdb. Thoughts on what to do at this point? smart_report.txt
July 28, 201411 yr The SMART report is actually not bad ... so I'd just wait and see if the rebuild completes. If the 2nd disk actually fails, there's nothing you can do to rebuild disk2 at that point ... you'll simply have to reinit the array without the two failed disks and reload the data for those two disks from your backups.

I like to imagine that garycase knows he's subtly scolding people for not backing up their important data when making these kind of posts.
July 29, 201411 yr No scolding intended ... it's an honest comment. If two drives fail, you simply have to restore the data from your backups. I assume anyone who has important data has it backed up ... if not, then the data must not be important to them. Personally, I can't imagine why anyone wouldn't keep backups of data they don't want to lose.
