Andrew, Thanks for the feedback. Please do let us know if you run into more problems. I'll put this warning on my list of things to check into when I get time.

A patch is attached. Thanks, it seems to work fine after some preliminary testing. I use stable branch from svn revision 9510. However, I still get these warnings on mkdir operations: Oct 03 22:14:02 [kernel] ------------[ cut here ]------------ Oct 03 22:14:02 [kernel] WARNING: at fs/dcache.c:1291 d_set_d_op+0x97/0xb0() Oct 03 22:14:02 [kernel] Hardware name: ProLiant BL2x220c G5 Oct 03 22:14:02 [kernel] Modules linked in: pvfs2(O) md5 nfsd 8021q garp stp llc ipt_REJECT ipt_LOG xt_pkttype xt_limit xt_tcpudp xt_hashlimit xt_recent xt_conntrack iptable_ filter iptable_mangle iptable_nat nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_NOTRACK iptable_raw ip_tables x_tables nf_conntrack_ftp nf_conntrack [last unloaded: microcode] Oct 03 22:14:02 [kernel] Pid: 17042, comm: tar Tainted: G W O 3.2.29-unicluster #4 Oct 03 22:14:02 [kernel] Call Trace: Oct 03 22:14:02 [kernel] [<ffffffff81033d5b>] ? warn_slowpath_common+0x7b/0xc0 Oct 03 22:14:02 [kernel] [<ffffffff810d54e7>] ? d_set_d_op+0x97/0xb0 Oct 03 22:14:02 [kernel] [<ffffffffa00f18fe>] ? pvfs2_create_entry+0x51e/0x860 [pvfs2] Oct 03 22:14:02 [kernel] [<ffffffffa00f8094>] ? pvfs2_get_custom_inode_common+0xfb4/0x1a50 [pvfs2] Oct 03 22:14:02 [kernel] [<ffffffff810cca5b>] ? vfs_mkdir+0x7b/0xc0 Oct 03 22:14:02 [kernel] [<ffffffff810d03dc>] ? sys_mkdirat+0xbc/0xd0 Oct 03 22:14:02 [kernel] [<ffffffff81409c7b>] ? system_call_fastpath+0x16/0x1b Oct 03 22:14:02 [kernel] ---[ end trace 8531668dbe98933b ]--- I'm unsure if it is safe to operate under such conditions. Usually slowpath warning is a harbinger of a lock condition. I'll keep you in touch if I'll have any faults with this issue.
