I currently have two data disk that are so old that need replacement and the parity drive it's almost full. So I bought two disks, one 4Tb for parity and one 2tb for data.
What I want is to replace the parity with the new 4TB, then replace the first data drive with the new 2tb and then recycle the "old" 2tb parity drive for the second old data drive.
All of this under a AUFS pool.
Any suggestions on the correct way of doing that?
I'm currently replacing the parity drive. I attached the 4TB drive and added to the array as a new parity+content, and then launched a sync. As it complained about a totally empty content file y executed the suggested command to force sync from cli. then I suppose that I'll remove the old parity disk from the Snapraid gui and launch sync again.
