[Gluster-devel] Setup recommendations - 2 (io-threads)

[Anton Khalikov]

One more question. The documentation says:

> NOTE: io-threads translator is useful when used over unify or just
below server protocol in server side

What about AFR translator ? 

Is it ok at all to have the following setup at the client side or
io-translator must be after afr and before booster ? Or may be even
better at server side ?

volume brick1
 type protocol/client
 option transport-type tcp/client     # for TCP/IP transport
 option remote-host 10.0.0.1      # IP address of the remote brick
 option remote-subvolume vdsbrick        # name of the remote volume
end-volume

### Add client feature and attach to remote subvolume of server2
volume brick2
 type protocol/client
 option transport-type tcp/client     # for TCP/IP transport
 option remote-host 10.0.0.2      # IP address of the remote brick
 option remote-subvolume vdsbrick        # name of the remote volume
end-volume


volume vdsafr
 type cluster/afr
 subvolumes brick1 brick2
end-volume

volume vdsbooster
 type performance/booster
 #option transport-type tcp # Default is 'unix', which is mostly used
when booster is loaded on client side.
 subvolumes vdsafr
end-volume

volume vdsiot
 type performance/io-threads
 subvolumes vdsbooster
 option thread-count 8
end-volume

volume vdswb
 type performance/write-behind
 option aggregate-size 128KB # default is 0bytes
 option flush-behind on      # default is 'off'
 subvolumes vdsiot
end-volume

volume vdsra
 type performance/read-ahead
 subvolumes vdswb
end-volume


Server side:

volume vdsbrick
 type storage/posix
 option directory /var/lib/gluster/vds/
end-volume
