Hello,

Have been reading through the 'how to' pages and am just wanting to confirm the steps to replace a failed drive, and also add 2 much larger parity drives.

 

I currently have dual 6TB parity drives, 1 failed 2TB drive, I have bought 2 x 14TB drives to replace the 6TB parity drives, which I will then use to replace not only the failed drive but 3 x 2TB and 1 x 1TB drive that are still running on reiserfs.

 

I have been able to remove all of the data from the failed drive onto another 6Tb data drive, and run a parity check with no errors.

 

1:  should I remove the failed drive, add 1 of the 14TB in it's place, pre-clear it, remove that, pre-clear the second 14TB drive in that spot, then do a parity swap procedure?

 

Or,

 

2: Pull parity 1, add one of the 14TB disks, pre-clear that, then let parity rebuild if it passes the pre-clear, then do the same for parity 2 with the second 14Tb disk, then  pre-clear the 'old' 6TB parity disks before adding them to the array?

 

I'm thinking 2?

 

Cheers

 

Mitch

If I'm understating correctly this won't work, first step would be doing the parity swap.

 

2 works, but don't need to preclear the old parity disk.
