<br>
I created an eight-brick gluster 3.3.1 volume (2x replication) on<br>
eight CentOS 6.3 x64 systems. I was able to form and start the volume<br>
without issue. I was also able to mount it through /etc/fstab as a native<br>
glusterfs mount. I have a couple questions issues at this point:<br>
<br>
- On a client machine, "glusterfs" is not recognized as a valid type<br>
unless gluster-server is installed. This seems to contradict the<br>
documentation - wanted to make sure I'm not doing something wrong. More a<br>
clarification than issue here.<br>
<br>
- The glusterfs process is taking between 50% and 80% CPU on both<br>
the brick and client systems (these are fairly powerful, brand new servers).<br>
<br>
<br>
- No doubt linked to the above, the mounted filesystem hangs<br>
indefinitely when accessed. I tried an "ls -a" on the mounted filesystem,<br>
for example, which hangs forever. I tested this by mounting a brick system<br>
to itself and to a client which is not a brick and the same behavior was<br>
observed. Both were glusterfs mounts.<br>
<br>
There is nothing special about my deployment except for the use of<br>
transport = tcp,rdma. I am running on Ethernet now but will be migrating to<br>
Infiniband after this is debugged.<br>
<br>
Thanks for any advice,<br>
