I suspect there isn't a code change here, but rather a difference in the way Ubuntu is presenting its mount points. The plugin tries to enumerate and check all mounts. A better use might be to add the actual mount points to be monitored with -p
/usr/lib/nagios/plugins/check_disk -w '20%' -c '10%' -e -p / -p /var -p /boot 12.04: mount <snip> none on /sys/kernel/debug type debugfs (rw) <snip> 14.04: debugfs on /sys/kernel/debug type debugfs (rw,relatime) tracefs on /sys/kernel/debug/tracing type tracefs (rw,relatime) -- 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
