I had a power outage last week that corrupted the file systems on 2 drives.  One was recoverable with xfs_repair, but the other was not.  I cleared the unrecoverable(Disk 5 - 18TB) one, formatted it, and added it to the array.  It is rebuilding but oscillates between estimates of 250 and 400 days to finish.  I have seen errors on the main array display for both parity drives in the past and Disk 3 currently lists 128.

 

Checking Parity was extremely slow before the issues last week.  I ran Disk Speed and everything looked fine.  The Smart tests always passed.

 

I have attached the diagnostics report and the Smart report for the parity drives and Disk 3.  What is likely the issue(s) here?  Thanks in advance.

Adding info on the unrecoverable disk

Check/replace cables for disks 3 and 5 and try again.

I paused the rebuild and will check in the morning, thanks.

I checked the connections for power and data and switched Drive 3 over from the HBA to a free SATA cable.  The speed is about the same.  I have replacement data cables coming tomorrow.  Should I be swapping out the power cables as well?

IIRC for disk3 looked more like SATA, but could be either, or both.

Thank you for your help.  I replaced the SATA cables and also swapped from using a SATA power extension to adapters on an IDE power cable plugged into the power supply.  It's estimating about 27 hours at the start, though I understand it will slow down some during the process.
