c. Remove the export and communicate this to

the client.

3. List all available exports on the NAS and identify the

problematic export. It must have an indication that it

is not accessible.

4. Delete the export or create the directory where the

export points to.

NFS Owner Restricted Operation

Description

NFS client is not permitted to perform the requested

action to the specific file.

Cause

NFS user attempted a chmod or chgrp operation while

not being the owner of the file.

Workaround

This is a minor, user-level issue. Frequent events of this

type may indicate a malicious attempt to access restricted

data.

NFS Write To Read-Only Export

Description

NFS client tries to perform modifications on a read-only

export.

Cause

An NFS export can be defined as a read-only export. A

client accessing a read-only export cannot perform write

operations or modify included files.

Workaround

This event, by itself, does not require any administrative

intervention.

NFS Write To Read-Only Volume

Description

An NFS user tries to modify a file on a read-only volume.

Cause

A NAS volume becomes read-only when it is set as the

target in a replication relation. Modifying a read-only

volume is inhibited, until the replication relation is

removed and the volume returns to a simple, normal state.

Workaround

Inform the user(s) of the state of the NAS volume.

NFS Write To Snapshot

Description

An NFS user tries to modify a file located in a snapshot.

Cause

NAS volume snapshots cannot be modified by design.

Workaround

Snapshot data cannot be modified. A snapshot is an exact

representation of the NAS volume data at the time of its

creation.
