March 31, 20179 yr Hi All, Thanks for stopping by and reading ...... Ok here goes:- Parity 2TB Parity2 3TB disk 1: 2TB disk 2: 2TB disk 3: 1TB disk 4: 1TB disk 5: 1 TB disk 6: 2TB "Picture is a thousand words" I want to replace 'disk 4: 1TB' with a larger 3TB drive. I know that any replaceable 'data disk' must as large or larger, as long as it's no larger than the parity disk..... 1) Stop the array. 2) Unassigned the drive I want to replace. 3) Remove the drive. 4) insert the larger disc. 5) start the array. In the 'Array Operation' box I get this:- Stopped. Disk in parity slot is not biggest. If this is a new array, move the largest disk into the parity slot. If you are adding a new disk or replacing a disabled disk, try Parity-Swap. When I do the 'Parity-Swap' procedure it does the same..... Is the problem caused with one of the 'parity discs' being 2TB Or Do I have to replace the 2TB parity with the 3TB disc ....... So I Have 2 x 3TB Parity Discs stumped again Thank for reading ...
March 31, 20179 yr Community Expert The size of the parity disk must be equal to or larger than the largest data drive, this is true for both parity disks.
March 31, 20179 yr Author Hi johnnie.black Thanks for getting back so quick (again) Thanks for clarification, so I'll swap the 2TB parity and replace it with larger 3TB Use the removed 2TB to goto Disk 4: in the array to get an extra 1TB more space ... again many thanks .....
March 31, 20179 yr Community Expert Seems like there should be a way to rebuild 2 disks at the same time here since you have dual parity, but since one of the rebuilds is the parity disk, and the replacement for disk4 is currently parity, I'm not sure you could get unRAID to let you do it. I wonder if johnnie.black has ever tried it?

March 31, 20179 yr Author Hi Both Just put the original drive back int slot 4 .... 'Parity-Sync/Data-Rebuild In Progress' approx 1Hr.21Mins to go ..... Then I'm back where I started After that I'll replace the 2TB parity with The new 3TB so I have 2 x 3TB parity drives Cheers ........
