Solution 1374351.1 : Sun Storage 7000 Unified Storage System: NDMP restore in progress at mountpoint

Applies to:

Sun ZFS Storage 7420 - Version All Versions and later
Sun Storage 7110 Unified Storage System - Version All Versions and later
Sun Storage 7310 Unified Storage System - Version All Versions and later
Sun ZFS Storage 7120 - Version All Versions and later
Sun Storage 7210 Unified Storage System - Version All Versions and later
7000 Appliance OS (Fishworks)

Symptoms

The BUI is reporting a mount error:

"The following errors were encountered while trying to share this filesystem.
As a result, the data may not be available over all protocols. NDMP restore in progress at mountpoint"

Some shares becomes unavailable to the client following a cluster failover.

Cause

The mount operation failed due to a NDMP restore in progress at the mount point.

Maintenance > Logs > Alerts shows ndmp_backup_inuse

Tue Oct 11 10:50:20 2011: failed to mount pool-0/local/ora-proj/ora-share: {txtid: "AKTXT_NAS_NDMP_BACKUP_INUSE", args: []}

This is most likely a known issue - where the share 'In Use' property is still set after an aborted NDMP backup or takeover happened during NDMP backup.

This issue is tracked via Bug 15748883 (AKTXT_NAS_NDMP_BACKUP_INUSE NDMP restore in progress at mountpoint).

Solution

The solution is included in Appliance Firmware Release 2011.1.5.0

As a workaround, restart the NDMP service through BUI

Configuration > Services > NDMP -> restart ('opposing circular arrows' icon at the right-hand side of the line)

or alternatively through CLI using:

> configuration services ndmp disable

> configuration services ndmp enable

If problem persist restart akd (see Doc 1543359.1 for possible data services impact)

> maintenance system restart

or alternatively reboot the NAS head.

Engage Oracle Support via a Service Request to bring back shares without rebooting.

An alternative workaround is to mount the volume and reshare the shares.
Engage an Oracle engineer for assistance as this operation requires access to the appliance Solaris shell.
# zfs mount pool-0/local/ora-proj/ora-share
# share /export/ora-proj/ora-share

Alternatively restart akd or reboot the head.
In cluster, ensure both cluster heads are either in CLUSTERED, OWNER or STRIPPED
before restarting akd.
