ZFS pools/filesystems created manually do not persist.

[rwaltman]

As title says, ZFS vol/fs created manually via console commands,

(A) are not visible via the web interface.
(B) are not imported automatically when rebooting the system.

I can live with (A), but (B) is a "show stopper" for me. I can not use the web GUI to create the volumes, because I do not want to allocate the whole disk to a single pool. [Details of my setup below]

How do I make FreeNAS "remember" the ZFS configuration and swap settings?

Thanks,

Roberto Waltman.

-----------------------------

Details:
I have a system with 5x1TB drives.
I want to use two pools of the same capacity (1596G,) one raidz1, the other raidz2.
The 100 Mbyte free area is to accommodate replacing a failing disk with a new one that doesn't have exactly the same number of sectors.

Some more information - Following the advice on another thread, I exported, (via cli,) both pools and then performed a "reset to factory defaults".
After rebooting, I can see both pools in the Storage --> Auto Import Volume, but I can import only one.
After importing either vol_1 or vol_2, the other one does not show up in the list anymore.
(It reappears if I export the volume that was imported succesfully)

This is expected behaviour for versions prior to 8.2. One of the new features in 8.2 is "ZFS is now integrated in that any ZFS operations that are performed at the command line are now reflected in the GUI. This means that you can now create pools, datasets, snapshots, and zvols in either the command line or the GUI and they will stay in sync with each other. "

Thanks for the reply.

> "... any ZFS operations that are performed at the command line are now reflected in the GUI."

Yes, that was my expectation. Unfortunately, it doesn't (fully) work.
I did not mentioned this in my post, but I am running the latest version:

[root@freenas] ~# uname -a
FreeBSD freenas.local 8.2-RELEASE-p6 FreeBSD 8.2-RELEASE-p6 #0: Wed Apr 11 10:19:51 PDT 2012 jpaetzel@build.ixsystems.com:/home/jpaetzel/fn_build/8.0.4/obj.amd64/build/home/jpaetzel/fn_build/8.0.4/FreeBSD/src/sys/FREENAS.amd64 amd64
( This is on an HP Proliant Microserver, and I did a clean install, not an upgrade. )

New filesystems/datasets created via the cli are visible in the GUI, but only after exporting/inporting, and only in one top-level pool.
I have two top-level pools, and only one, (either one,) can be imported via the GUI. The other becomes invisible.
So, I can import it manually, but I can not use the GUI to create shares, etc. The second pool import also vanishes when restarting the NAS.
It seems the system expects the disks to be allocated to only one pool. (Ignoring swap space.)
I will experiment a little bit over the weekend - If I can not get this to work, I will have to switch to a single top-level pool, or go back to Solaris... :(

Roberto,

You are making a very common mistake, that version number you posted is for FreeBSD. If you look in "System Information" in the GUI, you should find the FreeNAS version. I am pretty certain you are not using FreeNAS 8.2.

http://sourceforge.net/projects/freenas/files/FreeNAS-8.2.0/

Thank you very much, sir. You are right - I downloaded 8.2 BETA 3, but it seems I picked the wrong ISO when I made the install CD-ROM.
I installed from a disk that was labeled 8.2.0, but actually contained 8.0.4.

*BUT*, I installed 8.2, (clean, no upgrade,) verified I'm running the right version (FreeNAS-8.2.0-BETA3-x64 (r11188)) and the problems remain.
I have to pools named 'vol_1' and 'vol_2'. Both are listed in the "Auto Import Volume" menu. After importing either one, the other is not available anymore.

That sounds like a bug that should be reported as a ticket in support.freenas.org.
