Gluster users - Oct 2011 - How to rescue from Gluster Storage platform

we have 4 shared volumes in the storage platform but all of a sudden the
platform stopped responding. when I try connecting through webcontrol panel
it gives as

Template folder (/var/tmp/templates_c) is not available

when I connect the monitor to the server it comes with a new kinda login
screen just like windows and it hangs there... what could be wrong how do i
get back my data? please help me... im badly stuck...

Sandy
