Hi, I've made a pvfs2 cluster to agregate storage from 2 machines. The machines run Linux Debian etch with 2.6.22.19 linux. All is well, both machines are identical with 3Ware raid controllers, and write disk thruput is about 550MB/s. Each machine has 4 GigEth ports. I've dedicated 2 of them to link the machines together (bonding, 802.3ad) for the pvfs traffic, the 2 others are connected to the outside world. The purpose is to provide a rough ftp/samba storage thru the VFS layer, and it works fine.
However the performance is abysmal : the network thruput between the nodes is 8MB/s while copying! the total cluster write performance (cp from local disk to pvfs storage) is 17 MB/s.... What can be going so wrong? Any hint would be appreciated. -- -------------------------------------------------- Emmanuel Florac www.intellique.com -------------------------------------------------- _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
