Ok, just in case the nfs cause ocfs2 hang, should I just powercycle that hang box and ocfs2 will resume to normal? -----Original Message----- From: Sunil Mushran Sent: 23/03/2011, 9:23 AM To: Thomas Lau Cc: ocfs2-users@oss.oracle.com Subject: Re: [Ocfs2-users] bug resolve yet for export OCFS2 volume to NFS client ?
Last I checked readdirplus was not in nfs4. But you may want to reconfirm. readdirplus is a rpc call initiated by the client. So has to be disabled on the nfs client.
