1 title: Options of mounted filesystems
7 This check monitors the options with which a filesystem is mounted by
8 using the output of {/proc/mounts}. In normal operation mount options
9 should never change. In recent versions of Linux (e.g. UBUNTU oneiric),
10 the mount option {commit=} may change automatically depending
11 on the current battery state, so this option is being excluded from
12 the monitoring. Also excluded is the option {localalloc=} for recent
13 kernels and OCFS2 filesystems.
15 This check goes critical if the mount option {ro} appears. This
16 might indicate IO errors have occurred, causing the filesystem
17 to switch to read-only mode.
19 Any other change of mount options will trigger a warning state.
21 If the filesystem is not being found mounted, the check returns
25 The mount point of the filesystem.
28 All filesystems which are not of the type {tmpfs} will be monitored.
29 The inventory uses the current mount options as check parameter.
30 Note: the agent sends only filesystems which have a device below
31 {/dev}, so network filesystems and virtual filesystems are excluded
