[lustre-discuss] client server communication half-lost, read-out?

[Thomas Roth]

Hi all,

we are suffering from "temporarily unavailable" OSTs, where "temporarily" is a slight understatement, 
should read "permanently".

Evicting the client on the OSS manually or deactivating+activating the OSTs in question works without 
problems.

However, the clients are never evicted on Lustre's own. Obviously, the communication between client 
and OST is not dead entirely.


Is there a way to read out the communication between such an osc - obdfilter pair? As the network 
people do with wireshark et al.?

Cheers,
Thomas
