Millions of errors during rebuild. syslog only has 2 secs worth of errors. Rebuild again?

Featured Replies

EDIT: Shares dissapeared. So if I need to rebuild again I want to know if I can stop, remove the drive being rebuilt then add it back and start rebuild?

Also makes me wonder if the drive I replaced was ok and didn't need replacement if something else is failing, like PSU, or even my UPS? I had 7 CRC errors on the drive I replaced. Errors are on disk 1 and on 2nd drive but both seem to have no SMART errors except 1 CRC on disk 2...

UDMA_CRC_Error_Count are problems communicating with the disk, not problems with the disk. Possibly the disk you replaced had nothing wrong with it.

A common reason for problems when replacing a disk is disturbing the connections of other disks. Looks like that has happened with disk1.

You can't reliably rebuild any disk unless all other disks can be reliably read.

Can't tell anything about your user shares, maybe because of these other problems.

Shutdown, check connections on all disks, SATA and power, both ends, including splitters. Reboot and post new diagnostics.
