Hey guys,
I have a 3 node local disk file system that had a core dump during some
testing. It is an upgraded fs from 2.6 to 2.8.2. After the upgrade, I ran a
couple of utilities like pvfs2-ping and pvfs2-statfs. After those succeeded,
I attempted to create a new file of around 800K, and the first server died.
There wasn't anything useful in the logs or dmesg. Below is a backtrace from
the core file. I can supply the entire file, but I can't email it at 43M.
This may be related to the precreate-pool-race patch from a few days ago
since the backtrace indicates it was in the vicinity of those code changes.
Let me know what else I can supply that will help.
Bart.
