rrdcached error messages after reboot

1. offizieller Beitrag

    I have set up a completely new x86_64 system including OMV 5.3.2. Everything worked out fine out of the box! :)


    Just one little thing:


    After every reboot I get two mails at the same time:




    I checked rrdcached with
    systemctl status rrdcached
    Result: Service rrdcached is running.


    syslog:


    This just happens on reboot.
    So, is something messed up with the order of starting services on reboot?

    I've the same problem/situation.


    output of /etc/default/rrdcached:

    Can be fixed by omv-salt deploy run rrdcached.

    Thanks, try it tonight (the reboot).


    See the BASE_OPTIONS has a value now.

    My /etc/default/rrdcached looks exactly like Frepke's:


    I will try omv-salt deploy run rrdcached asap.

    Running omv-salt deploy run rrdcached didn't solve the problem.


    /etc/default/rrdcached now looks a bit different:


    After a restart I got the 2 mails mentioned above again.


    syslog (cat /var/log/syslog | grep rrdcached:(

    output systemctl status rrdcached:


    Perhaps this is related to the Buster /var/run symlink to /run thing? Just a guess, because of "Failed to connect to RRDCacheD at unix:/var/run/rrdcached.sock: Unable to connect to rrdcached: No such file or directory" while booting.

    Got this error after reboot


    rrdcached plugin: Failed to connect to RRDCacheD at unix:/var/run/rrdcached.sock: Unable to connect to rrdcached: No such file or directory (status=2)

    Coming back to this issue.


    After I saw a change in the changelog regarding /var/run -> /run, I updated OMV to 5.3.4.
    I checked /etc/default/rrdcached and still found /var/run in it.
    So I executed omv-salt deploy run rrdcached. After that the new paths to /run instead of /var/run appeared in the file.


    I rebooted my system and still got those error mails.
    In the syslog I found several of these entries again:


    What puzzles me is that it still tries to connect to /var/run/rrdcached.sock instead of /run/rrdcached.sock.


    I searched my system for references to /var/run/rrdcached.sock (*.pid) and/or /var/run/collectd.socket.
    I found several references to /var/run in the files inside /etc/collectd/collectd.conf.d.
    In addition I found in /etc/init.d/rrdcached (do we sill use init.d?): PIDFILE=${PIDFILE:-/var/run/${NAME}.pid}


    Is it okay to change the paths in these files to see if that causes the error while booting? Or is there a command similar to omv-salt deploy run rrdcached in order to update the paths in /etc/collectd/collectd.conf.d ?

    Partial success!


    I redeployed collectd with omv-salt deploy run collectd und rebuild all with omv-salt stage run deploy as suggested.


    I tried a reboot two times. In both cases no more error mails regarding rrdcached came in.


    But i still see error messages in my syslog:


    The path to the socket changed as wanted. But rrdcached still has problems while restarting.


    I dug a little further and found this at GitHub:
    https://github.com/collectd/collectd/issues/1948
    So perhaps this is a problem on upstream side.


    Whatever: After each restart the service rrdached is started slightly delayed.

    Fixed in openmediavault 5.3.5, see https://github.com/openmediava…99b7e898e16613292077064fa.

    Hi,


    Running OMV 5.5.3-1(usul)


    I'm having a similar issue, I've tried the suggestions above but still getting this error over and over again in syslog:


    OMV collectd[839]: rrdcached plugin: Failed to connect to RRDCacheD at unix:/run/rrdcached.sock: Unable to connect to rrdcached: No such file or directory (status=2)


    I'm a very novice user so any help appreciated.

    I had this problem and in my case when I checked service status I had a

    Warning: Fake start-stop-daemon called


    I did the following to fix:


    # mv /sbin/start-stop-daemon.REAL /sbin/start-stop-daemon


    Something to do with OS not cleaning up properly or install problem.
