FreeNAS as an NFS Client?

[neils]

Would like to mount one FreeNAS NFS volume to another FreeNAS volume for regular terabyte sized transfers. How is a permanent NFS mount, or a permanent autofs request configured that persists across FreeNAS reboots?

I meant to say, would like to mount one FreeNAS NFS volume to another FreeNAS host ...

Are you wanting to simply have replication of one server to another?

regular terabyte sized transfers

That is quite a lot, mind if I ask why so much data?

There's nothing preventing you from manually mounting a NFS export, I'd advise you do it via an init script opposed to editing the fstab, because in the past people have modified this and broke their FN box.

Now, is NFS something you need to use? If you're trying to copy/replicate data, why not use ZFS replication? This would be far more efficient.

Could rsync but given size of move(s), thought I'd avoid the ssh encryption overhead if possible.

I don't quite understand the configuration file strategy of FreeNAS. Changes to, for example, /etc/fstab do not persist across reboot. Don't know if an rc.local is either. Or perhaps it's saved in a nonvolatile /usr/local/etc maybe.

Just set the encryption cipher to disabled.

Just set the encryption cipher to disabled.

I think I'd have to have ssh re-compiled to enable a 'disabled' cipher.

Again, why not ZFS replication? Rsync will copy the whole file, replication will transfer only the deltas.

Also, tell SSH to use 'arcfour', it's based on RC4 and is the fastest algorithm without disabling encryption.

so ... no way to establish a persistent NFS client mount?

Not if you use ZFS replication:

The replication looks like a nice alternative.
But our users prefer to xfer subdirectories of data at will and at their choosing.
(the FreeNAS NFS client is bound to an ldap and is now [see below] mounting home directories)

After reviewing m0nkey's advice, I found the Init/Shutdown GUI in 'Tasks' and have
- manually mounted the needed NFS share
- configured the mount as a post-init command

Apologies to all for not reading the friggin manual.
And many thanks for your suggestions!

Glad you got it sorted :)
