[Pvfs2-users] Multiple data stores on one machine

[Steve]

Murali,
 
I ve started a new mail as formatting was messing up. Thanks for the help so
far :-)

/etc/pvfs2-server.conf-caos1
StorageSpace /pvfs2-storage-space
HostID "TCP://caos:3334"
LogFile /tmp/pvfs2-server.log
 
/etc/pvfs2-server.conf-caos2 
StorageSpace /pvfs2-storage-space
HostID "TCP://caos:3335"
LogFile /tmp/pvfs2-server.log

I then did 
 
Pvfs2-server /etc/pvfs2-fs.conf /etc/pvfs2-server.conf-caos1 -f
Pvfs2-server /etc/pvfs2-fs.conf /etc/pvfs2-server.conf-caos2 -f
 
Then started 2 servers
 
Pvfs2-server /etc/pvfs2-fs.conf /etc/pvfs2-server.conf-caos1
Pvfs2-server /etc/pvfs2-fs.conf /etc/pvfs2-server.conf-caos2
 
Is that correct that I need to run 2 server daemons ?
 
The mount command then seems a little confusing 
Mount -t pvfs2 TCP://caos:3334/pvfs2-fs /mnt/pvfs2
As you only reference one port.
 
In this instance I started with genconfig editing the files to get a
starting point. Can you explain the numbers and how a would choose the range
to add another files store ? Is it a simple as calculating the difference
from one range and adding that to last one used ?
