August 9, 20205 yr Hi all Currently got Unraid running with 2 data drives and 0 parity. I just bought a new drive for parity. Is there anything special I need to do apart from pre-clear the new drive and then mount it as parity? Thanks
August 9, 20205 yr Author thanks looks like if I want 4th drive I need a sata card as ran out of ports haha
August 9, 20205 yr If that day comes consider getting one of the LSI SAS cards.. where a regular SATA PCI card is limited to the number of ports physically on the card (typically 2-4-5 ports), the LSI SAS card generally allows for 4 SATA drives on each port.. so a card with 2 ports actually lets you use 8 SATA drives.
August 10, 20205 yr If it is a new drive, I would pre-clear your drive first to make sure the disk is healthy. Once that is successful, then you can add it to the array. The Preclear plug in is available from the community applications "Apps" tab at the top. If you don't see "Apps" then install that plug in first, then install the preclear plug in, then preclear your disk. I am pretty sure you know this as well but your parity disk must be the largest disk in your array. If the disk you are installing is smaller than the other two, its not going to work.
