Tom Sealey Posted July 1, 2021 Share Posted July 1, 2021 (edited) Hi all, I hope you can help. I have an existing cache drive, and NVMe SSD. I use it as a cache and also the appdata drive for docker containers. It's backed up nightly to the main array. I would like to add a second to create a cache pool for redundancy. Is this possible since it has data on it already? Thanks Edited July 1, 2021 by Tom Sealey Changed title Quote Link to comment
itimpi Posted July 1, 2021 Share Posted July 1, 2021 What file system is in use for the current cache drive? If it is BTRFS then yes you can add a drive at any time. If it is XFS then you would first need to back it up elsewhere as a multi-drive pool HAS to use a BTRFS file system. 1 Quote Link to comment
trurl Posted July 1, 2021 Share Posted July 1, 2021 The title you have given this thread says you want to add HDD to this pool? Not recommended to mix HDD and SSD. Quote Link to comment

Is there any docs on adding an additional drive? Quote Link to comment
