I’m so hooked on Centos lately I have no clue how to find the version of ZFSĀ installed on a proxmox (debian based) OS. A “hacky” way is checking dmesg during module load but I’m sure an easier solution must exist.


dmesg | grep ZFS

# if nothing, then perhaps it was not loaded (?)
modprobe zfs

result :

 dmesg | grep ZFS
