The actual write that is being done during the lustre_process_log is when the llog is being copied from the remote server to the local server.  I assume this is at least a necessary step and no getting rid of the llog without some sort of overhaul.

In fact, this config llog copying should only be done on the first mount of the OST, or if the configuration has changed.

We've actually removed this entirely for the 2.4 release, though that doesn't help you now.

Cheers, Andreas
