Kim,

Thanks for your reply. Lots of things there! I have merged my answers with your questions below although haven't tried everything yet. Perhaps my answers might give a few more clues to the problem though.

Is /afs available on other AFS clients? That rules out some possibilities.


Yes, on some of them. 50% have this problem though.


I'd go to a well-behaved client, cd /afs, fs flushv, cd /afs and see if /afs
is still available on that client.

Yes, tried this and /afs was still available.



I'd also be interested in


  vos exa root.afs
  vos exa root.afs.readonly

vos exa root.afs gave (on well behaved client):


root.afs                          536870915 RW          4 K  On-line
   rsl155 /vicepa

   RWrite: 536870915     ROnly: 536870916
   number of sites -> 3
      server rsl155 partition /vicepa RW Site
      server rsl156 partition /vicepa RO Site
      server rsl59 partition /vicepa RO Site

vos exa root.afs.readonly gace:

root.afs.readonly                 536870916 RO          4 K  On-line
   rsl156 /vicepa

root.afs.readonly                 536870916 RO          4 K  On-line
   rsl59 /vicepa
   RWrite  536870915 ROnly          0 Backup          0
   MaxQuota       5000 K
   Creation    Tue Dec  9 13:48:39 2003
   Last Update Tue Dec  9 13:48:39 2003
   1576 accesses in the past day (i.e., vnode references)

   RWrite: 536870915     ROnly: 536870916
   number of sites -> 3
      server rsl155 partition /vicepa RW Site
      server rsl156 partition /vicepa RO Site
      server rsl59 partition /vicepa RO Site

to see if the root.afs and root.afs.readonly volumes are on line, though if /afs is available on other clients the output is moot.

rxdebug <hostname> 7001 will give you some info about activity on the AFS
client's callback port

On a working client:


rsl55:/afs/.uk.baplc.com# rxdebug rsl55 7001

On a broekn client:

df to see if /afs still appears in the output

/dev/logsarc 9469952 6327480 34% 244 1% /logs/archive AFS df: /afs: No such file or directory




You don't mention the debug level of your fileserver. kill -HUP <PID of
fileserver> will set debug levels to 0 (default). kill -TSTP bumps one
level per kill -- to levels 1, 5, 25 -- some experiments I've done (but not
yet repeated) indicate some performance impact at debug level 25 but none at
levels 1 or 5. Not sure if anything would show up so might try this late in
the game.


Create a new volume on the fileserver, mount it, make sure it's accessible.

Check the afsd startup arguments and make sure that

[-rootvol <name of AFS root volume>]
and
[-mountdir <mount location>]

don't change the default root volume (root.afs) or default root directory
(/afs).  Unlikely but worth checking pro forma.

afsmonitor -cm <hostname> -fs <hostname> -freq 5

will tell you if there's any activity on the cache manager/fs ;  you're
probably not interested in -fs if the fileserver is behaving
orrectly.  -freq 5 specifies 5 second update interval instead of the 60 sec
default.  Your mileage may vary.  I like to see numbers change more
frequently than every minute.

When was the client last confirmed working correctly?

It was working until 10th April.



Kim
