[Pvfs2-users] PVFS2 Too Slow

[Nasr Y.M.J.O.]

Hello Murali,

Thanks for the hints. Regarding pvfs2 1.5.1, I compiled berkeley db 4.3.29 
from source and later compiled pvfs2 1.5.1 pointing to it. Everything is 
working fine. My question is, I have two databases now, the old one which 
handles the cluster and the new compiled one which is for pvfs2, will there 
be any troubles later on? I compiled the new db (4.3.29) statically in /opt 
directory and pushed it to all nodes. So far, no errors in all tests and the 
kernel space commands are just fine.

Regarding mpich, Ill send you the log file offlist in a separate email.

Thanks for your help.
