With btrfs, interestingly enough never lost data, but got volume stuck to read only mode (fsck didn't help) multiple times over the years. On sad note qgroup qouta (it is fancy qouta - you can limit disk usage per subvolume basis https://btrfs.readthedocs.io/en/latest/btrfs-quota.html#performance-implications https://btrfs.readthedocs.io/en/latest/btrfs-quota.html#perf... sounds much more positive than real impact :/ although didn't test with latest kernel ) starts struggle when there are load using 5 users (using docker containers with jupyterhub) and when load goes near 10 docker instances, new docker container creation literally crawls - start taking minutes
