Question

Posted

I have 14 drives in two pools. One pool/drive letter is used for Plex so there are 10-ish main folders within and thousands of folders within that. On that pool, I have data duplication on. &nbsp
I need to change my plex server to unraid and so I need to understand how the best way is to remove each drive from the pool and not lose the data. I can point Plex to each drive as that occurs as needed but I’m just a little perplexed on how to do this. 
I love drivepool but it’s not built for unraid. Thanks.

Hi, when you use the Remove function of DrivePool on a disk that is part of a pool it proceeds to move the contents of that disk's poolpart folder to the other disks in the pool, so long as those other disks have enough room, after which the disk can then be safely physically removed. It will normally ensure that all duplicated files remain duplicated as part of this process unless you tick Remove's "Duplicate files later" option (in which case it might move the files and then find out there isn't enough room to re-duplicate them, but that can be desirable in certain situations).

For example if you started with an unraid "array" of one disk you could:

  1. Move enough files from pool to array to have a disk's worth of free space in the pool.
  2. Remove a disk from the pool.
  3. Add the disk to the array.
  4. Repeat steps 1-3 until all of the disks have been removed from the pool and added to the array (obviously when you get down to one disk the pool won't be able to do duplication).
