trying to unload nfsd

trying to unload nfsd

I have umounted all of my nfs filesystems and stopped the nfs services.
I still can't unload the nfsd module:

$ sudo /sbin/lsmod | grep nfsd
nfsd                  277152  4 
exportfs                7680  1 nfsd
lockd                  77616  1 nfsd
nfs_acl                 5120  1 nfsd
sunrpc                174840  7 nfsd,lockd,nfs_acl

The only thing I can see that could be pinning it still is:

$ grep nfs /proc/mounts
sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 0 0

But I can't seem to umount that:

$ sudo umount /var/lib/nfs/rpc_pipefs
umount: /var/lib/nfs/rpc_pipefs: device is busy
umount: /var/lib/nfs/rpc_pipefs: device is busy

What could be pinning that fs/mount-point?

Nothing in the sunrpc module depends on anything in nfsd as you can see
from the above lsmod output.

I'd rather expect that you've forgotten to kill off rpc.mountd,
rpc.idmapd and/or rpc.svcgssd.

Right... here is what I do to unload both nfsd and sunrpc
service nfs stop && service rpcidmapd stop &&
umount /proc/fs/nfsd  && rmmod nfsd
rmmod lockd && rmmod nfs_acl
umount /var/lib/nfs/rpc_pipefs && rmmod sunrpc

(Note: this assumes there are entires in /etc/fstab
for both /proc/fs/nfsd and var/lib/nfs/rpc_pipefs.
It also assumes the Secure NFS gssd daeamon are not
running).

steved.
