IamSpartacus Posted February 18, 2018 Share Posted February 18, 2018 What's the process for replacing a 2 drive cache pool with a single (different) drive? Link to comment
trurl Posted February 18, 2018 Share Posted February 18, 2018 Is the 2 drive pool raid0 or raid1? Do you want the single drive to be btrfs? Link to comment
JorgeB Posted February 18, 2018 Share Posted February 18, 2018 Just remove one of them, instructions are in the FAQ, difficult to link since I am on a phone. Link to comment

Right now they are in RAID0. I want to remove BOTH drives, and replace them with a single DIFFERENT drive. Is there any advantage of using btrfs for a single drive over XFS? Link to comment

Just stop the array, unassign both and assign the new one. 23 minutes ago, IamSpartacus said: Is there any advantage of using btrfs for a single drive over XFS? Only if you care about checksums and snapshots. Link to comment

trurl Posted February 18, 2018 Share Posted February 18, 2018 Be sure to see the FAQ if you need to keep the data.

I don't have a lot of data on cache at this moment so it will be easy to copy it back after re-assigning the new drive. Link to comment
trurl Posted February 18, 2018 Share Posted February 18, 2018 That FAQ tells you how you can use mover to get the data off cache onto the array and then use mover to get data that belongs on cache back on cache. Link to comment
