Hi, I'm seeing rather frequent (several times per minute) log entries like:

I'm using glusterfs 3.2.6 on Debian Squeeze, and seeing the very same problem on different servers. It only seem to affect directories. -- Tomasz Chmielewski http://wpkg.org _______________________________________________ Gluster-users mailing list [email protected] http://supercolony.gluster.org/mailman/listinfo/gluster-users
