NFS - Network File System
- NFS is a network file sharing protocol like SMB/CIFS
- NFS allows multiple users to mount the same filesystem over a network
- NFS works well with the Citrix Hypervisor (XenServer) and XCP-ng hypervisors
- NFS is simpler to manage than iSCSI (block storage)
- May use bonding for higher availability
- iSCSI may offer better performance
- May use MPIO for higher availability

Troubleshooting
NFSv4: https://www.suse.com/support/kb/doc/?id=000017244
If you are having root squash problems, you might be able to specify
vers=3 as a client mount option to get around the issue.
NFSv4 handles UID maping differently than NFSv3. In NFS v4 with
idmapd, the same username@domainname must be recognized by both sides, or it will be mapped to nobody (regardless of root squash).
mount # show client mount details umount /path/mountpoint mount -a tail -30 /var/log/syslog nfsidmap[nnnnn]: nss_getpwnam: name 'root@somedomain.tld' does not map into domain 'localdomain'
ps aux | grep idmapd vim /etc/idmapd.conf Domain = somedomain.tld nfsidmap -cv # clear cache
