I am receiving an error on a client trying to access a gluster mount (/pfs2, in this case). [2011-03-28 12:26:17.897887] I [dht-layout.c:588:dht_layout_normalize] pfs-ro1-dht: found anomalies in /. holes=1 overlaps=2 This is seen on the client in the /var/log/glusterfs/pfs2.log, which is the mount point associated with that storage. All other clients accessing the same storage do not have the hanging symptom, and have no such entry in their logs. One possibly helpful note - this node worked fine until I upgraded the client from 3.1.1-1 to 3.1.3-1 on the x86_64 architecture, running CentOS 5.2. Even after I completely uninstalled GlusterFS from this node and reinstalled 3.1.1-1, the problem persisted. Here is the RPM info: root at jc1lnxsamm33:~# rpm -qa fuse fuse-2.7.4-8.el5.x86_64 root at jc1lnxsamm33:~# rpm -qa "glusterfs*" glusterfs-fuse-3.1.1-1.x86_64 glusterfs-core-3.1.1-1.x86_64 glusterfs-debuginfo-3.1.1-1.x86_64 Servers are 4 Replicated-Distribute machines running CentOS 5.5 and GlusterFs 3.1.3-1.
