- Snapshots fail to mount for AIX managed file systems
- Snapshots fail for Linux Volume Manager on VNX with PowerPath
- Linux Logical Volume Manager snapshots fail with an error
- NetWorker to Media-Clone stops responding and the backup fails
- File-by-file or saveset restore fails
- Restore of raw devices fails on Linux with permission issue
- Command nsrsnap_recover -I runs but fails to restore a file
- Restore fails with disk signature error
- Directed restore files and folder permission issue

NetWorker 19.7 Snapshot Management Integration Guide
NetWorker support of cluster environments
In a cluster configuration, NetWorker creates snapshots from file systems on a virtual node. The cluster’s virtual node and physical nodes must be NetWorker clients. The following figure shows an example of the data flow for a snapshot and clone in a cluster environment.
