[OpenAFS] Problem with large data transfer (WinNT AFS, please HELP!)

[Lubos Kejzlar]

Hi all,

   we are trying to extend our (long lived) campus-wide Unix-based AFS
infrastructure (Transarc AFS 3.6 DB servers, mix of Transarc/OpenAFS clients)
to end-user workstations running Win 98/NT/W2k as a main distributed
storage solution.

Unfortunately, our users experienced _significant_ problems during pilot
phase:

- all significant tests are running on Win NT SP5 workstations. Similar
  problems are reported by Win98 users (smaller amount of data, not proved
  yet by support people)

- as an part of automated SW installation, there is need to copy large
  subtree from AFS to local file system (there is no possibility to run SW
  directly from AFS space, unfortunately):

     - all data are readable to system:anyuser
     - both client & server are using 100baseT-FD network connections and
       there are no communication problem during tests
     - total amount of data copied is about 2+ GB
     - there is large number (70+ k) of small files to copy
     - all data are located in single volume

- unfortunately, we are _UNABLE_ to copy such data using (any) different
  methods (MS Explorer, Perl-based command line tools, etc.):

     - the copy process breaks at random (AFAIK) point with following error
       events (occurred roughly at same time in system/application event log):

       EventID: 3013
       The redirector has timed out request to xxxxxx-afs ...

       EventID: 1009
       cm_Analyze: HardDeadTime exceeded ....

       and/or (?)

       EventID: 1005
       Pkt straddled session startup, took xxxxxx ms, ncb length xxx.

    - there are no active CM RX connections (from rxdebux) and system seems
      to be 'frozen' for a while, during error event (AFAIK).


Does someone ever seen similar problems??

Currently it's really _HIGH_PRIORITY_ISSUE_ for us to provide and support
single distributed FS infrastructure for all our users (10000+), so we are
looking for _ANY_HELP_OR_SUGGESTION_ (I'm not very familiar with M$
Windows, but I'm able (glad) to provide any further info for someone could
help us)!

So again thank you VERY MUCH in advance for _ANY_HELP_OR SUGGESTION_ !!

Best regards,
     Lubos
