Introduction:

When creating snapshots of a Unix/Linux filesystem for backup, the cdm probe will see the snapshot as another mount.
 

Environment:

Most Unix and Linux operating systems have a built-in method to assist system backups by using filesystem snapshots.

A snapshot starts with freezing the filesystem, then (particularly in Linux) creating a logical volume and mounting the filesystem image to it.  This is then accessible to the backup utility.  When backup is complete, the snapshot is unmounted and destroyed.

Instructions:

If you don't want the snapshot to be part of your cdm monitoring, you can use the Ignore Filesystem option within the probe.

The value should be a regular expression that would match all disks and/or file systems you want the probe to ignore. Here is an example how to ignore Auto-mounted disks that are recognized on each "disk interval":
