Filesystem based resources, such as fs.sh and clusterfs.sh, required usage of the /tmp directory during status monitoring. If the /tmp directory became full after mounting the filesystem, the monitor action would fail even though the filesystem is correctly mounted.
Healthy mounted filesystems failover because the /tmp directory is full.
We no longer make use of the /tmp directory during filesystem monitors.
Filesystem monitors do not fail if the /tmp directory is full.
