[Pvfs2-users] Anyone using 2.8.1 on BG/L ?

[Andrew Pochinsky]

Hi Phil,
	I think it's only pvfs client. I've ran a test on Sam's request  
(trying to write a 200+MB file from mmcs on an IO node, which  
reproduced the problem) and placed the logs of the pvfs client and  
servers at

<http://www.mit.edu/~avp/BD498E4E-34BA-45BD-9EF9-AE302C2D507C/200D35FA-D8DA-4E78-8AA8-C1336B0EF3F1/

During the tests, pvfs2-client, pvfs2-client-core and cp all hang, cp  
did not respond to kill nor kill -9, pvfs2-client could be only killed  
-9.

Some times a smaller file could be written (or read) without a  
problem, but if the total amount of I/O is large enough, pvfs still  
gets stuck.

Hope it helps,
