I did the following: # btrfs filesystem defragment -czstd -r -v /home and changed the fstab entry: # grep /home /etc/fstab UUID=8e1f7af4-c0bf-434e-b1c4-a9af2c810d56 /home btrfs subvol=home,discard=async,compress-force=zstd 0 0 (this is an SSD, hence the discard-async) I then rebooted, but find: # btrfs prop get -t i /home compression # (i.e. no output) and the space usage doesn't seem to have changed. Is there something I've misunderstood? poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
