Dell FluidFS NAS Solutions Administrator's Guide

Description

During a system shutdown using the NAS Manager, the system does not stop and the controllers do not shutdown after 20 minutes.

Cause

The system shutdown procedure is comprised of two separate processes:

• Stopping the file system
• Powering down the NAS cluster solution controllers

The file system may take a long time to clean the cache to the storage either due to lot of data, or due to an intermittent connection to the storage.

During the powering down stage, the issue can be due to the OS kernel hanging on the controller or failing to sync its state to the local drive.

Workaround

If the file system has stopped and if one of the controllers are still up, you can physically power down the controller using the power button.

If file system has not stopped, you must let it continue working. The file system reaches a 10 minute timeout, flushes its cache to the local controllers, and continues the shutdown process.
