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!

    root@NAS-OMV:~# systemctl status nfs-blkmap

  • 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.

  • I'm facing exactly the same problem: I got it after migration from OMV4 to OMV5 and it generated erratic reboot of my NAS.

    Yesterday, I decided to do a fresh install of OMV5: still exactly the same issue, causing multiple reboot every day.

    May you please tell me if you solved it and how did you do?

    I'm really wondering why all OMV5 users are not facing the same problem...

    OMV5 64bits - Intel i5-7400

    4 * 2TB Hdd Raid 5 + 1 SSD 128Go

  • Encountered the same issue after an OMV4 -> 5 update.

    Removing both, nfs-blkmap.service and nfs-utils.service, resulted in a "broken pipe" error after reboot. However, keeping nfs-utils.service and just removing nfs-blkmap.service, as you've suggested, fixed the syslog error for me, too.
