zfs discuss - Feb 2010 - Idiots Guide to Running a NAS with ZFS/OpenSolaris

At the risk of getting myself flamed with my very first post, will someone
please point me to the ''Idiots Guide to Running a NAS with
ZFS/OpenSolaris''?

I wish.  I especially wish it had been around the summer of 2006.

This is one of the better things out there:
<http://breden.org.uk/2008/03/02/a-home-fileserver-using-zfs/>

And falling back on
<http://www.solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide>
is often useful.

(I''ve just been adding a controller and a new hot-swap bay, moving my
boot
disks down to 2.5" drives in the new mini hot-swap bay, and moving towards
adding a third pair of disks to the data pool.)

My one near-philosophical conclusion (applying to home-scale NAS; probably
many small business environments too really):  Use mirror pairs rather
than RAIDZ groups.  This lets you upgrade in smaller increments and more
safely, rather than having to buy say 5 bleeding-edge drives all at once
to upgrade, and putting your pool at risk through 5 resilver cycles.  With
a mirror you can attach another disk BEFORE you detach the old disk, so
you can upgrade without risk.  At today''s disk sizes and prices, 100%
redundancy is affordable, and it makes lots of other things simpler and
safer.

For some requirement sets (capacity need, data retention need) this
doesn''t fit though; temporary video storage, say, that you''re
willing to
do without if something goes wrong worse than RAIDZ can handle.

hello
you could try my napp-it zfs server

it''s a zfs server, a minimal opensolaris-based server installation,
together with a web-gui - suitable also for non-solaris people -
easy to install, ready to run

use either nexenta (new version based on snv 133) or opensolaris/eon
- at the moment i would prefer nexenta

see

I don''t think there is a guide like that but honestly, it''s
not that hard
for most of it.

It also really depends on what your hardware is...how you plan to set it up
and all but once you install it, getting CIFS and NFS working is dirt simple
(though the ACL''s can be somehwhat more difficult, though i just create
a
group "nas" and use something like this:

/usr/bin/chmod -R A=\
owner@:full_set:d:allow,\
owner@:full_set:f:allow,\
group:nas:full_set:d:allow,\
group:nas:full_set:f:allow,\
everyone@:rxaARWcs:d:allow,\
everyone@:raARWcs:f:allow \
/tank/nas/


which seems to work well.  I also use something like this:

/usr/bin/chmod -R A=\
owner@:full_set:d:allow,\
owner@:full_set:f:allow,\
user:wonslung:full_set:d:allow,\
user:wonslung:full_set:f:allow,\
everyone@:rxaARWcs:d:allow,\
everyone@:raARWcs:f:allow \
/tank/nas/Wonslung

but anyways, which part do you need help with.  Most of it is fairly straigh
forward for simple nas.

Installing is pretty simple.  creating a zpool is pretty simple, enabling
cifs is pretty simple, creating shares once you have it is pretty simple.
The ACL''s were what gave me the most trouble at first which is why i
made a
point to post them.  (being really new to solaris i kept trying to use the
wrong chmod and it didn''t work)
but the main thing is: google is your friend.
