@arcanicanis@were.social Stratis uses XFS only for data and deduplication.

it uses LVM for RAID, snapshots, SSD cache and erasure coding.

however when I tried it, RAID LVM was fucking slow with erasure coding turned on, and the SSD cache makes reading even slower somehow; even after the balancing was finished, the I/O speeds were completely unusable, I could not access the data in any practical way and I had to give up on that data and go back to ZFS and restore from backup
