Hi,<br>
<br>
After changed configuration, performance is slowly. I added
write-behind, read-ahead into my configuration. But performance become
bad.<br>
<br>
1,2,3's config:<br>
volume storage1<br>
type protocol/client<br>
option transport-type tcp/client<br>
option remote-host 210.245.xxx.xxx<br>
option remote-subvolume locks<br>
end-volume<br>
<br>
volume writeback<br>
type performance/write-behind<br>
option cache-size 1MB<br>
option block-size 1MB<br>
subvolumes storage1<br>
end-volume<br>
<br>
volume readahead<br>
type performance/read-ahead<br>
option page-size 2MB<br>
option page-count 16<br>
subvolumes writeback<br>
end-volume<br>
<br>
4's config:<br>
volume brick<br>
type storage/posix<br>
option directory /store<br>
end-volume<br>
<br>
volume locks<br>
type features/posix-locks<br>
subvolumes brick<br>
end-volume<br>
<br>
volume server<br>
type protocol/server<br>
option transport-type tcp/server<br>
option auth.addr.locks.allow *<br>
subvolumes locks<br>
end-volume<br>
<br>
You can check this at: <a class="moz-txt-link-freetext" href="http://mirror-fpt-telecom.fpt.net/">http://mirror-fpt-telecom.fpt.net/</a><br>
<br>
Any suggestions?<br>

Sorry, my bad. Got a little confused.
The problem with your config is that you should export the "locks"
volume from the server and specify "locks" as the remote-subvolume in
client.
So your configuration should be:
1,2,3's config:
volume storage1
type protocol/client
option transport-type tcp/client
option remote-host 210.245.xxx.xxx
option remote-subvolume locks
end-volume
4's config:
volume brick
type storage/posix
option directory /store
end-volume
volume locks
type features/posix-locks
subvolumes brick
end-volume
volume server
type protocol/server
option transport-type tcp/server
option auth.addr.locks.allow *
subvolumes locks
end-volume
</pre>
