Hello to all , first sorry for my english not my first language
i have reset my openmediavault and have mounted the zfs via nfs and to my surprise was empty.... i look and this is not my zfs it's only 100MB
I go to the openmediavault gui and i obtain the next message:
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; zfs list -H -t snapshot -o name,used,refer 2>&1' with exit code '1': /dev/zfs and /proc/self/mounts are required.
Try running 'udevadm trigger' and 'mount -t proc proc /proc' as root.
i see that i have the zfsplugin installed.
i have try to apt-get update and upgrade and reset and don't seems to works
I think that my problem is with the kernel and the zfs because the command:
systemctl
give this information:
systemd-journal-flush.service loaded active exited Flush Journal to Persistent Storage
systemd-journald.service loaded active running Journal Service
systemd-logind.service loaded active running Login Service

● zfs-mount.service loaded failed failed Mount ZFS filesystems
● zfs-share.service loaded failed failed ZFS file system shares
● zfs-zed.service loaded failed failed ZFS Event Daemon (zed)
the dots are services that have failed
and the command:
root@tokyo:~# modprobe zfs
modprobe: FATAL: Module zfs not found in directory /lib/modules/4.19.0-0.bpo.5-amd64
now i don't remember if i was using the normal kernel or the kernel of a plugin for the zfs
The kernel now is:
Linux tokyo 4.19.0-0.bpo.5-amd64 #1 SMP Debian 4.19.37-5+deb10u2~bpo9+1 (2019-08-16) x86_64 GNU/Linux
and sorry but i have done via the GUI
apt-get clean
apt-get update
apt-get upgrade
apt-get dist-upgrade
but i don't have the zfs , what is the best option to go, from this point to obtain the plugin-zfs and don't lose the data and the pools in the drives that have the zfs
in the gui i see that all the drives are ok, but i have very little experience with the zfs, and i will wait to the knowledge of the people of the forum.
Many thanks in advance
