Pre-requisites - - - Create a GlusterFS volume - - - Install nfs-ganesha (refer section 5) - - - Disable kernel-nfs, gluster-nfs services on the system using the following commands - - service nfs stop - - gluster vol set <volname> nfs.disable ON (Note: this command has to be repeated for all the volumes in the trusted-pool) - -### 2.) Configure nfs-ganesha for pNFS - - - Disable nfs-ganesha and tear down HA cluster via gluster cli (pNFS did not need to disturb HA setup) - - gluster features.ganesha disable - - - For the optimal working of pNFS, ganesha servers should run on every node in the trusted pool manually(refer section 5) - - *#ganesha.nfsd -f <location_of_nfs-ganesha.conf_file> -L <location_of_log_file> -N <log_level> -d* - - - Check whether volume is exported via nfs-ganesha in all the nodes. - - *#showmount -e localhost* - -### 3.) Mount volume via pNFS - -Mount the volume using any nfs-ganesha server in the trusted pool.By default, nfs version 4.1 will use pNFS protocol for gluster volumes - - *#mount -t nfs4 -o minorversion=1 <ip of server>:/<volume name> <mount path>* - -### 4.) Points to be noted - - - Current architecture supports only single MDS and mulitple DS. The server with which client mounts will act as MDS and all severs including MDS can act as DS. - - - If any of the DS goes down , then MDS will handle those I/O's. - - - Hereafter, all the subsequent nfs clients need to use same server for mounting that volume via pNFS. i.e more than one MDS for a volume is not prefered - - - pNFS support is only tested with distributed, replicated or distribute-replicate volumes - - - It is tested and verfied with RHEL 6.5 , fedora 20, fedora 21 nfs clients. It is always better to use latest nfs-clients - -### 5.)
