FreeNAS SMB share mount error(95): Operation not supported
TL;DR: either mount with higher security using
mount -t cifs //freenas/share /mnt/share -o vers=3\.0,username=me
or lower FreeNAS's SMB share security to NT1
The long version:
FreeNAS is probably the best NAS software available for any price. Unfortunately, I was having trouble mounting its SMB shares on my Linux desktop or my XenServer hypervisor. After a bit of Googling and a bit of trial-and-error, I've come to the conclusion that mount.cifs version 6.4 defaults to a SMB protocol version weaker than SMB 2. Windows 7 seems to require SMB 2, and Windows 8 and 10 seem to prefer SMB 3. FreeNAS will support all of these versions and more, but by default only allows connections using SMB 2 through SMB 3.
The best solution would obviously be to use a newer protocol and to change your fstab to include vers=3.0 among your comma-separated list of options and when you want to manually mount something use vers=3\.0 among your comma-separated list of options.
If you can't or won't use a newer protocol, you can instead lower the standards of your FreeNAS server by logging into its web interface, clicking "Services" then "SMB" and changing the "Server minimum protocol" to NT1.
Either of these options work for me using FreeNAS 9.10.2-U2, Ubuntu 16.04.2, and XenServer 7.1
