Date: Mon, 29 Jun 2009 16:33:02 +1000 From: db <db.pub.mail@...il.com> To: Chuck Lever <chuck.lever@...cle.com> Cc: Frans Pop <elendil@...net.nl>, Netdev <netdev@...r.kernel.org>, Linux Kernel <linux-kernel@...r.kernel.org>, Trond Myklebust <Trond.Myklebust@...app.com>, Linux NFS mailing list <linux-nfs@...r.kernel.org> Subject: Re: svc: failed to register lockdv1 RPC service (errno 97). I'm running arm 2.6.30 kernel and a 2.6.30 kernel on my desktop. I see this "[1257016.190000] nfsd: last server has exited, flushing export cache [1257018.250000] svc: failed to register lockdv1 RPC service (errno 97). ." On both ends. The arm is running debian lenny (armel). The desktop is debian lenny (32bit i368). When this error i cannot continue to transfer files. Here is the config of the /etc/exports and what i try to use "/media/nfs_shares/rsync/ *(rw,no_subtree_check)" i mount on the desktop with [root@...ktop ]# mount 192.168.1.12:/media/Y/W/ /media/mount_point/ -o soft and i try using rsync like this (from my desktop). rsync -av --progress /home/User_NAME/BACKUP/Y/W/X/ /media/mount_point/W/X and it just hangs. I then try to unmount it and i have problems doing so. so i need to force the umount "19051.391800] Performance counters on [319051.391804] input device check on [319051.391807] Actions configured [399843.223405] RPC: Registered udp transport module.
