fatrace does not see file access on zfs filesystem

[roland aus köln]

i have a samba/zfs server and don't see any file access activity on /zfspool.

even "touch /zfspool/test" does not work

[roland aus köln (devzero-c)]

apparently, you can make it work for the current cwd with "-c" : https://github.com/zfsonlinux/zfs/issues/6079

Does that zfs pool appear in /proc/self/mounts anywhere? That's what fatrace reads in default mode (when not using -c/--current-mount).

Yes it does:

dozer/scripts /dozer/scripts zfs rw,noatime,xattr,posixacl 0 0

As of 2021-12-17: the zfs file system seems to get ignored on line 379 (ctrl+f "only consider").

I attempted adding a condition to not ignore "zfs": 'strcmp(mount->mnt_type, "zfs") != 0'

However this lead to 'fatrace: Received unexpected event info type 52'.
