Replace parity disk

Recommended Posts

I am a noobie and new member to the forum. I was able to build my first unRaid server by following this forum and many YouTube videos available. I especially want to thank Spaceinvader One for his detailed step by step videos.

I have a basic question....Is the process of replacing a parity disk the same as replacing a data disk? I have a 2tb parity disk, 2tb data disk, and 2x 1tb disks. I would like to increase my parity disk from 2tb to 4tb and then over time expand the data disk to 4tb each. Any help would be greatly appreciated.

Thanks

It’s essentially the same.  Before you start check the SMART status of all your data drives, you want them to be in good shape.  I’d also run a parity check and make sure it is clean and turn off automatic start of the array.  Then you’d stop the array and unassign parity.  Power down, swap disks, start it back up, assign the new parity, and start the array.  Rather than rebuilding the drive, a parity sync will start.
