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 ceph version 9.0.3 (7295612d29f953f46e6e88812ef372b89a43b9da) [root@node0 /]# rpm -qa | grep fuse rbd-fuse-9.0.3-0.el6.x86_64 fuse-libs-2.8.3-4.el6.x86_64 ceph-fuse-9.0.3-0.el6.x86_64 [root@node1 /]# uname -r 2.6.32-504.el6.x86_64 [root@node2 opt]# cat /proc/version Linux version 2.6.32-504.el6.x86_64 (mockbu...@c6b9.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC) ) #1 SMP Wed Oct 15 04:27:16 UTC 2014 [root@node2 opt]# vim /etc/ceph/ceph.conf [global] fsid =7be14c22-5144-4a3e-9197-eaf02ac079d2 mon initial members = node0 mon host = 192.168.50.5 auth cluster required = cephx auth service required = cephx auth client required = cephx osd journal size = 1024 filestore xattr use omap = true fuse_disable_pagecache=true fuse_use_invalidate_cb=true osd pool default size = 2 osd pool default min size = 1 osd pool default pg num = 333 osd pool default pgp num = 333 osd crush chooseleaf type = 1 [mon.node0] host=node0 mon addr =192.168.50.5 [osd.0] host=node1 .... thanks
