Hello, quick question about the manual.

Under the recovery section the manual states that a client needs to 
invalidate all locks, or flush it's saved state in order to reconnect to 
a particular osc/mdc that has evicted it.

We've found that one of our 1.8 clients will frequently get into a state 
where many of the oscs report a 'Resource temporarily unavailable' state 
after an outage to a 1.6 LFS server. The LFS can be accessed again on 
the client by remounting the LFS, but it does not auto-recover.

My question is, how one goes about manually flushing the saved client 
state? I couldn't figure this one out from the manual, unless 'lctl 
set_param ldlm.namespaces.<OSC>.lru_size=clear' does it.

Thank you,
Adam
