Enable or disable Spotlight on a volume
You can use Xsan Admin to control whether a volume is indexed and searchable using
Spotlight.
Enable or disable Spotlight on a volume:
1 In Xsan Admin, select Volumes in the SAN Assets list.
2 Select the volume and choose Edit Volume Settings from the Action pop-up menu (gear).
3 Select or deselect the checkbox next to Spotlight and click OK.
Note: After you click OK, the volume restarts.
Enable extended attributes
If extended attributes were disabled on a SAN volume when it was created, and all
computers that use the volume are Macs, you can enable extended attributes for
the files on the volume. 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.
Extended attributes are enabled when you create a volume with Xsan 2.3, unless you
deliberately disable them.
Important: You can’t disable extended attributes. Enabling them on a volume is a one-
way process that can’t be undone.
WARNING: To avoid data loss, clients with Quantum’s StorNext File System (Windows,
AIX, IRIX, Linux, and Solaris computers) must not access volumes that use extended
attributes.
Macs clients of an Xsan 2.3 SAN must have Xsan 2.2 or later, which supports extended
attributes.
Enable extended attributes:
1 In Xsan Admin, select Volumes in the SAN Assets list.
2 Select the volume and choose Edit Volume Settings from the Action pop-up menu (gear).
3 Select the checkbox next to Extended Attributes and click OK.
Note: After you click OK, the volume is unmounted from all SAN computers, and then
remounted.
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.
