Ok the CREATE operations went through, but the STORE operations did not.

Does it show anything about CML entries pending for reintegration in the
cfs lv output?

If the client is write-disconnected, make sure you have tokens and try
cfs fr <dir> (aka. forcereintegrate)

That is writeback-caching, an extension to write-disconnected operation.

dasr/easr - Disable/Enable Application specific resolver execution.
Not really useful without a fully functioning helper application
(AdviceMonitor is broken, it's replacement the sidekick is under
development)
wd/wr - Force writedisconnected operation, or attempt to go back to
fully connected operation.
fr - Force all logged operations back to the server.
wbstart/wbstop/wbauto - All related to the writeback-caching extension.

Because all newly created volumes have a flag that disables writeback
caching. This code is still very fresh, and doesn't really work nicely
when several clients are hoarding the same files and have wb-caching
enabled. Writeback caching is similar to but not the same as
write-disconnected operation.

That is unusual, a client should refuse to get anything that would
exceed available cache-space. Cache Overflows are normally associated
with writing, the client only "realizes" how big a file as after it is
closed, and at that point it might be bigger than the cachesize or quota
would allow.
