NFS is how we serve files across the CS and cluster subnets, as well as the 10Gb and Infiniband subnets.
This page will also soon contain a pointer to an architecture diagram.
Mount points shared via NFS
CS:
- Home directories - hosted on Bowie, exported to all user-accessible hosts
- Archival home directories at
/eccs/clients- hosted on Bowie, exported to all user-accessible hosts
Cluster:
- Home directories - hosted on Hopper, exported to all user-accessible hosts
/cluster- hosted on Hopper, exported to all hosts
Allowing NFS in a firewall
Few of our servers run a firewall, but the cluster head nodes do (as of this writing). You want to make sure to allow calls to mount NFS, thusly:
firewall-cmd --permanent --add-service=nfs firewall-cmd --permanent --add-service=mountd firewall-cmd --permanent --add-service=rpc-bind firewall-cmd --reload
