No, the filesystem is completely inaccessible at this point.

However, I have another hint which seems to let autofs off the hook:

These happened on the NFS server around the time of the first report
of problems:
Aug 15 11:34:36 nas01 nscd: 14741 Error getting context of nscd
Aug 15 11:34:47 nas01 last message repeated 18 times
Aug 15 11:34:47 nas01 nscd: nscd shutdown succeeded
Aug 15 11:34:47 nas01 nscd: 21046 Access Vector Cache (AVC) started
Aug 15 11:34:47 nas01 nscd: nscd startup succeeded

(actually the first line has been appearing in the logs for ages; I
assume it's just more selinux stuff which I still don't understand.)

And then this morning:

Aug 17 10:16:12 nas01 kernel: nscd[14745]: segfault at 0000002afed9e933 rip 
000000552aab7cf2 rsp 0000000040c00750 error 4
Aug 17 10:16:27 nas01 kernel: nscd[21050]: segfault at 0000002b99607280 rip 
000000552aab7d08 rsp 0000000040c00750 error 4

so nscd definitely screwed up in some manner.  I restarted it:

Aug 17 10:30:27 nas01 nscd: 22346 Access Vector Cache (AVC) started
Aug 17 10:30:27 nas01 nscd: nscd startup succeeded
Aug 17 10:30:27 nas01 nscd: 22346 invalid persistent database file 
"/var/db/nscd/passwd": verification failed

and so far no reports of problems.

Sorry to try to lay any blame on autofs.  Just another tribute to how
impenetrable NFS can be.
