I put LVM on, and made a logical volume which left some space so I would have lots of flexibility in my array. There is a systemd service in Bullseye that creates a snapshot of LVM logical volumes, fscks the snapshot, and reports the result if there is an error. So I leave at least 20 GB available on my system disk for that. Leaving a chunk available for that on your RAID array strikes me as a good idea. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
