I ran these commands minutes after echother ane each time it is
trimming the entire free space
Anyone else seen this? the filesystem is the root FS and is compressed
You should be very happy that it is trimming at all. Typical situation
on a used btrfs is
# fstrim -v /
/: 0 B (0 bytes) trimmed
even if there is 33G unused space ob the fs:
# df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 96G 61G 33G 66% /
I think you're using an old kernel, this has been working since at least
4.5, but was broken in some older releases.
