hmm.. this is a bit odd... would it be possible to pust what your exports look
like as well as a bzip2 binary tethereal network trace? Something similar to:
tethereal -w /tmp/data.pcap host <servername>
Created attachment 141297 [details]
bzip2 thethereal -w output
/etc/exports:
/export *.cora.nwra.com(rw,sync,fsid=0)
/export/turb1 *.cora.nwra.com(rw,sync,nohide)
/export/turb2 *.cora.nwra.com(rw,sync,nohide)
/export/turb3 *.cora.nwra.com(rw,sync,nohide)
/export/timed2 *.cora.nwra.com(rw,sync,nohide)
What is really bizare here is that NFSv4 does not use or need mountd to mount or umount so why mountd is involved at all is pretty mind bending... Are you sure a v2 or v3 mount is happening after the v4 umount? This is all I'm doing: [root@cynosure ~]# mount -t nfs4 saga:/data1 /mnt [root@cynosure ~]# umount /mnt Nov 29 09:22:04 saga mountd[3860]: refused unmount request from cynosure.cora.nwra.com for /data1 (/): not exported /etc/exports: /export *.cora.nwra.com(rw,sync,fsid=0,no_root_squash) /export/data1 *.cora.nwra.com(rw,sync,nohide,no_root_squash) /export/amanda *.cora.nwra.com(rw,async,nohide,no_root_squash) /export/backup1 *.cora.nwra.com(rw,async,nohide,no_root_squash,insecure) /export/backup2 *.cora.nwra.com(rw,async,nohide,no_root_squash) No other mount traffic. what is the output of the 'rpcinfo -p server' command? # rpcinfo -p saga

Purposed patch
n turns out that the umount code was rpc pinging the remote
rpc.mountd even on NFSv4 mounts which is definitely wrong...
This patch fixes the problem....
Please let me know if you need an updated nfs-utils rpm..
That does appear to take care of it. I'll install on my other FC6 machines tomorrow and test it out further. Thanks! Fixed in nfs-utils-1.0.10-5.fc6 Confirmed. Thanks! |
