Tips and Tricks
Regarding mount points within shares
If you have a mount point within an NFS share, you must have a separate entry in your exports file that sets the permissions of this mount point. Currently OS X has a problem with this, but officially this is the way to do it.
Show hosts that are connected to this NFS server
showmount
Show what hosts are using what exports
showmount -a
Show exported directories
showmount -e
Show directories in use by NFS
showmount -d
Add an NFS mount to fstab
opal:/z4 /mnt/z4 nfs rsize=8192,wsize=8192,timeo=14,intr
Linux Tips and Tricks
Show which versions of NFS your NFS server supports
rpcinfo -p
Allow an OS X client to mount nfs4 nested zfs data sets
OS X has problems with the privileged port default requirement in nfs4, so the insecure
option is required.
The nohide
option allows you to mount nested zfs datasets, instead of requiring a separate export for each dataset.
/z4 *.local(rw,async,no_subtree_check,insecure,nohide)
OS X Tips and Tricks
Create persistent NFS mount in OS X 10.8
This is not bulletproof. Modern OS X 10.9+ version are switching away from NFS to CIFS. The NFS client on OS X is pretty weak. For instance it might crash your machine if the share has 0 bytes free but is mounted RW. Use at your own risk.
sudo mkdir /mnt # OS X doesn't like you playing with /Volumes, it may delete your dirs
