Thread: synching external filesystem to cluster

We have setup a Kusu Cluster system in our lab

We want to add an external filesystem to an existing cluster installer node, we are doing so by say the mount command.

mount 172.30.0.62:/big/public/ /mnt/tmp

Now when we want to make this file system accessible to all the other machines (compute nodes) of the cluster, is there any way to do it?? the cfmsync is not configured to do it so far.. Is there anyway to configure cfmsync for the same or some other method like using the exportfs ?

How do we use cfmsync to run commands throughout the cluster

Will be great if anyone can provide some lead in this issue... Thanks is advance

I'm not sure about mounting, but Kusu ships with pdsh for running commands on all the nodes in your cluster simultaneously.

Hi

To mount an external filesystem you can use the "fstab.append" file. It is in /etc/cfm/$NODEGROUP/etc/fstab.append

The format of this file is the same as the fstab file. It gets appended to the nodes fstab file. You might have to make the mount point if it does not exist.

The other thing to watch is the routing on the NFS server. It may not know how to route to the private network.
