[Gluster-users] loading 'features/posix-locks' on server side may help your application

[Vu Tong Minh]

Hi,

After changed configuration, performance is slowly. I added 
write-behind, read-ahead into my configuration. But performance become bad.

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

volume writeback
        type    performance/write-behind
        option  cache-size 1MB
        option  block-size 1MB
        subvolumes storage1
end-volume

volume readahead
        type    performance/read-ahead
        option  page-size 2MB
        option  page-count 16
        subvolumes writeback
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
