Re: svc: failed to register lockdv1 RPC service (errno 97).

[db <db.pub.mail@gmail.com>]

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@desktop ]# 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

I am only using nfs2. I am not using nfs4 / nfs3.

This issue is most troublesome as it breaks my use of nfs.
