== Information ==

'''OBS:''' Det går endast att logga in som root.

=== Rotfilsystem ===

Rotfilsystemet är ZFS och ligger på diskarna mfid[0-1]p2.

=== Lagringsyta för NFS === 

zpool storage med draid2. ligger på diskarna mfid[3-11]. Poolen är komprimerad med zstd.

=== NFS exporter ===

== NFS server (FreeBSD) ==

<code>/etc/rc.conf</code> should contain:

<pre>nfs_server_enable=&quot;YES&quot;
nfsv4_server_enable=&quot;YES&quot;
mountd_enable=&quot;YES&quot;</pre>
<span id="dataset"></span>
== Dataset ==

<code>zfs create storage/&lt;datasetname&gt;</code> <code>zfs set quota=&lt;size&gt; storage/&lt;datasetname&gt;</code> 

== Quota ==
Forstor uses ZFS datasets. Use <code>zfs set quota=2T storage/&lt;datasetname&gt;</code> to set quota Get quota with <code>zfs get quota storage/&lt;datasetname&gt;</code>

<span id="nfs-exports"></span>
== NFS-exports ==

<code>/etc/exports</code> should contain:

<pre>V4: /storage #root of nfs export
/storage/&lt;datasetname&gt; -maproot=&quot;nobody&quot;:&quot;nobody&quot; I.P.ad.dr #squasing root and exporting to specific IP</pre>
<blockquote>'''NOTE''': after making changes in <code>/etc/exports</code> restart mountd <code>service mountd restart</code> sometimes restart <code>nfsd</code> as well for good measure.
</blockquote>
<span id="nfs-client-ubuntu"></span>
== NFS client (Ubuntu) ==

Install package <code>nfs-common</code>

Test mounting the exported file system with <code>sudo mount -t nfs4 -o proto=tcp,port=2049 192.168.0.177:/&lt;datasetname&gt; /mnt</code>

Unmount with `umount.nfs4 /mnt/<datasetname>

If everything seems to work add the following to <code>/etc/fstab</code>:

<pre>192.168.0.177:/&lt;datasetname&gt; /mnt/&lt;datasetname&gt; nfs4 auto 0 0</pre>
to mount unmounted volumes from fstab do <code>mount -a</code>

<span id="users-and-groups"></span>
== Users and groups ==

All users who are to access this export need to exist both on server and client. With same IDs. They do not necessarily NEED to exist on the server, but it may be more convenient that way in case of ID conflicts later on on the servers side.

There needs to be a group set up that will be the owner of the shared directory on both sides. This also needs to have the same GID on both client and server.

I have tested on the servers side that the directory need only really have the group be correct. The directory can have root as owner and “forte” as group.
