August 11, 20169 yr Community Expert Doing a new config keeps all your data. -Take a screenshot of current disk assignments -Tools -> New config -Re-assign all disks, double check parity disk is in the parity slot, assign the new id disk in place of the old one -Check "parity is already valid" -Start array to begin parity sync You should then run a parity check.
August 11, 20169 yr Author ok so this is before.. and i moved disk 9 to another slot. so i should assign the same disk with the new ID to disk13 and then run the new config?
August 11, 20169 yr Community Expert Yes, but parity was not valid, so don't check the "parity is already valid" before starting the array, it will do a parity sync when it starts.
August 11, 20169 yr Author Ok thank you very much. Array back online and parity rebuilding. If the disk I moved from 9 to 13 still is acting up. What should be my next step being that parity isn't finishing it's sync. How can I replace the drive without a valid parity?
August 11, 20169 yr Community Expert You can't rebuild, you can do another new config with a new disk and after parity is synced copy all data from the old one.
August 11, 20169 yr Author You can't rebuild, you can do another new config with a new disk and after parity is synced copy all data from the old one. oh ok so just to confirm, if its still a problematic drive.. 1: swap it with another 2: run new config 3: do a parity sync 4: after the sync is completed pull the new drive and old then slave them and copy the data from the old to new then place the drive back into the array and sync again?
August 11, 20169 yr Community Expert Don't pull the new drive, use the unassigned devices plugin (or temporary assign the old disk to the cache slot) to copy all data to the array.

August 12, 20169 yr Author So the pre lead is still running slowly but still running. May end up replacing that drive.

August 14, 20169 yr Author also working/searching for a way to move the data off disk 13 to the other disk in the array.. edit: looks like "unBalance" may work edit2: well dang.. not enough space.. time to work on preclearing.
August 15, 20169 yr Author ended up replacing the failing disk with an unprecleared one.. the parity disk did its job and rebuilt it. now to work on the preclear script..
