File Layout
Accessing a storage system with pNFS
Step 0: Get pNFS kernel from git tree and install on all involved servers.
Step 1: Setup NFSv4 servers
- Create /etc/exports file on all DS's and the MDS.
/export *(rw,sync,fsid=0,insecure,no_subtree_check)
- Run the following commands on on the storage server<p>
rpc.mountd rpc.nfsd 8 exportfs -r or /etc/init.d/nfs start
Step 2: Load File Layout driver on clients
modprobe nfslayoutdriver
Step 3: Mount pNFS file system.
- On pNFS client:
mount -t nfs4 <i>"mds_server_name"</i>:/ /mnt/pnfs Note: Each file system has its own way of picking the MDS. Ensure you mount only the MDS and not a DS.
