RPC: sendmsg returned error 101

[Bill Rugolsky Jr.]

Trond,

Was this issue (i.e., kernel RPC generating ENETUNREACH) ever resolved
satisfactorily?  I can reproduce it consistently on two different machines.

There was a thread about it back at 2.2.2:
(http://www.uwsg.indiana.edu/hypermail/linux/kernel/9903.1/0019.html)

To rehash the symptoms:

When attempting to umount NFS during shutdown, I get a filesystem
busy message, (probably due to some shells with cwd on the mounted
filesystem), then the system loops endlessly printing:

RPC: sendmsg returned error 101

I am currently running a RH6.0 box with the following:

Linux 2.2.12-final3 + linux-nfsv3-0.10.1.dif.bz2 +
knfsd-1.4.7/nfsd-2.2.7-3.patch.

The mount version is 2.9o.

I have a NetApp mounted rw and two (fully patched) Solaris 2.5.1
hosts mounted ro.  I'm not exporting anything.

The relevant part of /etc/rc.d/rc6.d/ looks like:
K20nfs@
K80nfslock@
K85netfs@
K89portmap@
K90killall@

Magic-SysRQ is ineffective.
