What brand of SAN? Who reports the loss of disc space?
Is it windows or the SAN? Does the SAN make snapshots that take a lot of space 
(old gets removed after new is finnished?)

Have a strange one 
We have Exchange 
2003 running on 2 server in a cluster :
server A holds the 
exchange roles and cluster groups
Server B holds a 
huge data drive that holds PST files
Both servers attach 
to a fibre channel SAN for the drives
We are getting the 
Data drive reporting that no space is available when their is 21 GB 
When I fail the data 
drive to server A the drive appears and shows the full 21 GB free and all is 
well again.
If I fail back the 
drive will also be fine.
It is reporting no 
space randomly.
Against my better 
judgment the Drive was compressed quite a while ago but then more space was 
added from the free space available on the SAN.
Not sure if this 
last piece of info is relevant.
Any ideas were to 
even start as there doesn't seem to be any information in the event 
thanks in
