Hi Steve,
If you want to grow the existing file system, you would have to add
new servers each of which uses the new storage space. The new servers
should manage a non-overlapping set of handles with the existing set
of servers.
Then, you would have to umount the volume from all servers, stop all servers,
edit all the fs.conf to include the new server address/ports, restart
all servers and remount.
There is no way to do this online unfortunately right now..
So for example,
curreent servers are tcp://S1:P1 (storage space on /opt1), tcp://S2:P2
(storage space on /opt2) and you wish to add /opt3 to tcp://S3:P3.
NOTE: S1, S2, S3 can all be the same servers. P1, P2, and P3 need to
be different if they are all on the same server else they can be
same), So you would have to edit
<Aliases>
Alias localhost TCP://S1:P1
Alias localhost TCP://S2:P2
Alias localhost TCP://S3:P3 <-- new
</Aliases>
<Filesystem>
Name pvfs2-fs
ID 93349254
RootHandle 1048576
<MetaHandleRanges>
Range S1 4-4294967297
Range S2 4294967298-8589934591
Range S3 17179869180-21474836473 <-- new
</MetaHandleRanges>
<DataHandleRanges>
Range S1 8589934592-12884901885
Range S2 12884901886-17179869179
Range S3 21474836474-25769803767 <-- new
</DataHandleRanges>
<StorageHints>
TroveSyncMeta yes
TroveSyncData no
</StorageHints>
</Filesystem>
Hope this helps,
cc your emails to pvfs2-users from now on so that we could archive
these questions for everyone..
thanks,
Murali

Great to hear that..

Create a new set of config files server.conf and fs.conf. If you are
Using pvfs2-genconfig edit the config files to change the port numbers
And file system identifiers and strings...
I.e.
<Filesystem>
Name pvfs2-fs <-- change this to a new name
ID 1408503068 <-- this should be different from the already
Existing file system
...
And you are good to go.
Remember to use the new name to mount the new storage space etc..
In fact you don't even need to use multiple servers. You can have
Multiple storage spaces
Exported from a single server...
Add more than 1 <FileSystem> contexts in the same config file and
Restart the servers...
If it is still unclear, let me know..
Also read through the pvfs2-quickstart to set this up quickly..
Thanks,
Murali
