OMV4->5 residue cleanup blkmapd[275]: open pipe file /run/rpc_pipefs/nfs/blocklayout

  • Not sure if this problem existed when i was on OMV4, but i notice it when reviewing logs after OMV5 migration.

  • See the same thing on mine, and it is a fresh OMV5 install!

  • If it is a fresh installation, the following could help:

    there are still two old service units in /lib/systemd/system/



    Rename or move them, reboot the server and try again.

    If all is fine, you won. In any other case: rename/move them back and reboot again.

    Or just switch to SMB if you are able to.
