I found this from ocfs1.4 document: g) NFS OCFS2 volumes can be exported as NFS volumes. This support is limited to NFS version 3, which translates to Linux kernel version 2.4 or later. Users must mount the NFS volumes on the clients using the nordirplus mount option. This disables the READDIRPLUS RPC call to workaround a bug in NFSD, detailed in the following link: http://oss.oracle.com/pipermail/ocfs2-announce/2008-June/000025.html Users running NFS version 2 can export the volume after having disabled subtree checking (mount option no_subtre...

Hi folks, I just saw one of my FreeBSD servers (7.0-stable of June 2008) crash while trying to access the .zfs snapshot directory via a nfs client machine. The server got a page fault caused by the nfsd process. It wasn't even able to dump the kernel image anymore. Resetting the machine it first appeared to come back fine, but shortly before the login prompt the nfsd let it crash hard again

...her that is in the NFS client, Dovecot or Linux OS/kernel areas.?? We use LDAP for auth and I am doing some tuning in that area.?? The NFS filesystems are mounted with the options below: 10.11.0.238:/mailbox_store_01 on /home1 type nfs4 (rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,nordirplus,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.11.0.96,local_lock=none,addr=10.11.0.238) My dovecot config is below.?

...ther NFS clients. If you are using OCFS2 is such an environment and have experienced such lockups, look into disabling READDIRPLUS in the NFS clients. Refer to the NFS man page in your distribution for instructions on the same. On Linux, it typically is done by mounting with the mount option "nordirplus". Also, it would be helpful if all users using OCFS2 with NFS can let us know whether they have or not experienced the issue. Please include the number of nodes in the cluster, kernel version, OCFS2 version, the distribution running the NFS client and whether it supports disabling READDIRPLUS...
