Good Morning All,
We are trialing XEN/GFS in a dev network before moving it to a live
server base, the following outlines what we are doing and what we are
tring to achive
We have 4 physical Server, 1 of which has a 50gb Raid5 Array we wish to
export via GNBD, this is a simple scsi array and is not shared storage.
On top of this we have 8 "Xen Virtual Servers" They all need shared
access to this 50gb Array and have block level access via GNBD.
Right now the cluster is running as shown by
/root@chessmaster:~# cat /proc/cluster/status
Protocol version: 5.0.1
Config version: 3
Cluster name: ubernet
Cluster ID: 13910
Cluster Member: Yes
Membership state: Cluster-Member
Nodes: 5
Expected_votes: 5
Total_votes: 5
Quorum: 3
Active subsystems: 1
Node name: chessmaster
Node addresses: 202.xxx.132.12/
This is done by booting up all machines then doing the following in
order on all of them
/
cman_tool join -w
/etc/init.d/gnbd-client restart/
On the server with the 50gb array i also run
//etc/init.d/gnbd-server restart/
This allows me to see /dev/gnbd/50gb on all 8 servers, I then ran
/gfs_mkfs -p lock_dlm -t ubernet:50gbFS -j 10 /dev/gnbd/50gb/
Which completed fine, however attempting to mount it is proving tricky,
when i try and do the following
/ mount -t gfs /dev/gnbd/50gb /users//
I get
/mount: permission denied/
and in /var/log/messages i see

/
when i try and run fence_tool join -w i get this
/fenced: local cman node name "asimov" not found in cluster.conf/
Is anyone able to point me in the right direction, i really need to get
this dev network runnning asap.All we need is a basic GFS system so that
all our servers can access user's e-mails no matter what server they
connect to. Nothing fancy or full blown cluster, just a Shared Filesystem.
Here is my cluster.conf file
<?xml version="1.0" ?>
