Hi
While using ping_ping to test the cephfs file systems mounted by the ceph-fuse, i found it failed.
my cluster is 4 nodes. one mon/mds , three server(3 osd/server), OS : centos6.6 , add "fuse_disable_pagecache=true , fuse_use_invalidate_cb=true " in ceph.conf
[root@node2 opt]# ./ping_pong -rw /export/test/zzz 4
data increment = 1
^C 367 locks/sec
[root@node3 opt]# ./ping_pong -rw /export/test/zzz 4
data increment = 1
^C 402 locks/sec
[root@node0 /]# ceph -v
