(SOLVED) Drive not adding to array

[kbrutlag]

Hi all,

 

I moved all my drives over to SSD a while back and recently replaced an SSD partiy drive with a much larger HD.  I've tried adding the SSD to the array in an open spot (1) left over from the original move to SSDs.  I used the 'Unassigned Devices' to remove the old parity partition off the drive, now the drive shows as new (blue square) only.  Not sure why it's not the green circle.

 

Thanks for any assistance.

Blue is normal for a new device, it's gonna be cleared and when done it will change to green, then you'll need to format it.

If at all possible, I'd rather not 'clear' an SSD. Is there any way around that?

All drives being added to an existing array (with parity) must be cleared by the OS (if they aren't already pre-cleared) so that their state is consistent with the existing parity data, although if you're willing to take the chance on a drive failure you could issue a new config and then rebuild parity

You could use blkdiscard on the SSD then just write the preclear signature, but run a correcting check after to make parity is in sync, not all SSDs do blkdiscard correctly.

Thanks all.  I decided to just let the check run.  Don't like using up SSD cycles on a clear, but until UnRAID has a better way to handle all SSD arrays, guess we're stuck.
