I use this tool more than any other performance monitoring tool I’ve come across. It’s great for looking at overall network input and output, individual disks, and memory usage.
Use the ocfs2console gui to create the cluster.conf for you. Your first problem may be in creating the config by hand. Even if everything looks right including the permissions to the files and directories, the ocfs2 daemons may still not see the configuration at all.
Let’s start by configuring networking, then install a bunch of packages. After that we’ll configure services and create a gfs2 cluster file system. Finally we’ll relocate libvirt to the clustered storage so live migration will just work right out of the box.
After generating keys and authorized_keys correctly you encounter this error when shelling into the remote machines. Identity is the problem.
