Dell PowerVault NX3600 - Manual (Page 94)

• 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 could 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.
NAS Container Security Violation
Description NAS container security violation.
Cause Selecting security style for a NAS container dictates the
dominant protocol to be used to set permissions on files in
this volume. NFS for UNIX security style volumes and CIFS
for NTFS security style volumes.
Consequently, this makes some operations invalid:
• Setting UNIX permissions for a file in an NTFS
Security style container.
• Setting UID/GID ownership for a file in an NTFS
Security style container.
• Setting ACL for a file in a UNIX Security style
container.
• Changing read-only flag for a file in a UNIX
Security style container.
• Setting SID/GSID ownership for a file on UNIX
Security style container.
The NAS container security style must reflect the main
protocol used to access its files.
Workaround If a user frequently needs to perform a cross-protocol
security related activity, split the data into separate NAS
containers based on the main access protocol.
Multiple Errors Received During File System Format
Description You receive multiple errors during a file system format.
Cause Probable causes may be:
• Wrong SAN IPs are used in the Dell NAS Initial
Deployment Utility (IDU).
• Wrong IQNs used while defining hosts in the
MDSM.
