• 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

umount /path/mountpoint
mount -a
tail -30 /var/log/syslog

nfsidmap[nnnnn]: nss_getpwnam: name 'root@somedomain.tld' does not map into domain 'localdomain'
