Xsan Admin displays incorrect "Volume is not running" alert after upgrading Xsan metadata controllers to Lion
After upgrading an Xsan metadata controller (MDC) from Mac OS X v10.6 Snow Leopard to OS X Lion, Xsan Admin may display a warning triangle over an Xsan volume. Hovering the mouse pointer over the warning triangle reveals the following alert:
"Volume is not running on mdc2.example.com"
This message appears even though there is an fsm process for the volume running on the MDC named in the message.
Run these commands on each Xsan metadata controller that has been upgraded to Lion:
sudo rm -i /var/servermgrd/servermgr_xsan.lock sudo killall servermgrd
This issue does not affect MDCs upgraded from Lion to Mountain Lion.
