We normally netboot but we had a few machines that would not PXE, so we installed 14.04 via medium. Afterwards, some of the medium-installed machines were throwing this error in Nagios. Found this line in /etc/mtab on the afflicted hosts:
tracefs /var/lib/ureadahead/debugfs/tracing tracefs rw,relatime 0 0 This appears to be an artifact on the medium-based install process. I removed the above line and ran: sudo service nagios-nrpe-server restart Error condition cleared. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1516451 Title: check_disk plugin broken after upgrade to 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nagios-plugins/+bug/1516451/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
