Hello!
I try to create a simple cluster with 2 nodes.
I've done all required steps descriped in

http://www.mapr.com/doc/display/MapR/M3+-+RHEL+or+CentOS
and
http://answers.mapr.com/questions/94/can-m3-run-on-two-nodes-only

There are two VM nodes, based on CentOS 6.2. All services works but in web interface I have an error when trying to add available disk.

"Failed operation for disk sdb, Device or resource busy"

sdb is a virtual hard disk with 60 gb capacity. To use it, I put "/dev/sdb" string in disks.txt like in manual and then run disksetup. That was ok.

Only one problem that appeared was empty hostname file in /opt/mapr. And mfs service threw error, so I was set hostname manually.

I think that no one service keeps "dev/sdb" busy.

And I am not very good in linux so it's difficult for me to know what's the problem.
Thanks.
