Hello all! I was doing some tests with GlusterFS here and I think I found a bug. Current setup: 2 servers (192.168.0.151 and 192.168.0.155) and 1 client ( 192.168.0.155). How to reproduce: run "dbench -t 10 -c /usr/share/dbench/client.txt 50", CTRL+C after a few seconds, run "dbench -t 10 -c /usr/share/dbench/client.txt 50" again.
