March 27, 201610 yr So I just started rebuilding a 2tb data drive that failed and it's going 1% per day, I would wait it out but I need to move in 2 days and I'm pretty sure it won't finish. Can I stop the rebuild turn off the server, move and continue the rebuild? Thanks
March 27, 201610 yr Assuming everything is working as it should, you can't resume a rebuild, but you can restart a rebuild. However, you obviously have problems if it is going that slowly. Post a syslog.
March 27, 201610 yr Author So looking at the syslog it looks like Disk6 has a ton of errors while trying to rebuild Disk1, is all hope lost? Thanks syslog_copy.txt
March 28, 201610 yr Possibly just bad connection to disk6 caused when you were changing disks. Check all connections and try again. If it still happens post SMART for disk6.
March 28, 201610 yr Author smart on webgui is a red thumbs down. Can you tell me how to obtain a smart report to post? Thanks

March 28, 201610 yr Disk 6 is bad, IMO your best option, if you have the space, is canceling the rebuild, start the array with no disk assigned to disk1 and copy everything you can from the emulated disk1 and disk6. Success will depend on how bad disk6 is.
March 28, 201610 yr Author So it actually just finished, and Disk1 looks pretty good except it is showing faulty and I cannot run smart reports but it mounts and i can access the data, should I get another disk1 or should I try to rebuild disk6? Man this keeps getting worse. Thanks

Man this keeps getting worse. Thanks Do you mean disk1 rebuild finished? What exactly do you mean it is showing faulty? Post a SMART for that disk.
March 28, 201610 yr It didn't finish rebuilding, it probably dropped offline as there are also errors for disk1, is it a new disk? You'll need to power cycle the server to get a SMART report.
April 3, 201610 yr Author So it looked like disk 1 is fine, can I replace and rebuild the failing disk6 using the original parity now that 1 is whole? Thanks
