Multiple Mounting of one XFS Partition

[Steffen Knauf <Steffen.Knauf@xxxxxxxxxxxxxx>]

Hello,

i have 2 Servers which are connected with a raid via FibreChannel.
Both of them have mounted the same XFS-Partition. But if i change a 
Filepermission
or add some Files at the Partition of server1, the partition of server2 
don't show the modifications
until i remount the Partitions. I don't know how whether it is a cache 
Option or something else.
Perhaps someone have an idea.
Thanks!

greets

Steffen
