Enabling Extended Attributes

If all computers on your SAN are running Xsan 2.2, you can enable extended attributes
for the files on your volumes. When extended attributes are enabled, attributes
associated with a file are stored inside the file itself rather than in separate hidden files.
Enabling extended attributes improves file system performance.


You can’t disable extended attributes. Enabling them on a volume is a

one-way process and can’t be undone.

To enable extended attributes:


In Xsan Admin, select Volumes in the SAN Assets list.


Select the volume and choose Edit Volume Settings from the Action (gear) pop-up



Select the checkbox next to Extended Attributes and click OK.

The time needed to convert the volume to use extended attributes depends on the
size of the volume and the number of files stored on it.
