NFS Mount Path Does Not Exist

Identify the relevant export and the options defined for it, while focusing on the netgroup definition. Document the used netgroup in order to restore it after the issue is solved and remove the netgroup limitation.

Description Cause

Workaround

Client tries to mount a mount path that does not exists on a NAS container. This error usually occurs in one of the following scenarios:

•When accessing a system which is being restored from backup or remote replication. The full directory structure is available only when the restore is complete.

•When a client with an authorization to access a higher directory in the same path deletes or alters a directory which is being mounted by another client.

•When multiple users are accessing the same data set, it is recommended to apply a strict permission scheme to avoid this scenario.

1.If the NAS system is being restored, communicate the current status to the client and instruct the client to wait for the restore process to complete.

2.In the other case, there are three options:

–Restore the problematic path from a backup.

–Manually create the missing directories to enable the mount. Clients receive errors when trying to access existing data in a deleted path.

–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.
