Can't mount Directory(s) in Jail -( The Brig + owncloud )

[Flok]

Hello every one,

I have a really annoying problem and either i'm really stupid quite now or some thing seems wrong.

I made a Nas4free install on a new (old) Computer some weeks ago. Last week I finally managed to install the brig & owncloud within it. Every thing is set up and working and as last step I now want to mount my NASData to/in(?) the Jail.
I am working with the fstab-editor.
[I went to so some trouble before because I accidentally tried to mount to a Directory with a Space in the Name (not a goot idea). And afterwards restored from an old snapshot (know to work).]

After I got everything working again my fstab looked like this:

Code: Select all

/mnt/SichereDaten/Eigene_Musik /mnt/Daten/Jails/owncloud/mnt/Daten/aUser/files/Eigene_Musik nullfs rw 0 0

I tried to mount my Music into a User folder. Didn't work. Jail not starting mountd complained. (I forgott to save the kernel.log but if any one cares I guess I can reproduce the error). I have at least quadruple checked the spelling and if every path exists and so on.
"SichereDaten/Eigene_Musik" is a ZFS Dataset which is mounted unter /mnt/

As this didn't work I tried it with this:

Code: Select all

/mnt/SichereDaten /mnt/Daten/Jails/owncloud/mnt/SichereDaten nullfs rw 0 0

I though maybe the root-Dataset mounted to some folder will work, nope. It doesent.

Than I cleand the fstab and rebooted the "Server" to check if the Jail is at least starting now or if there is still a little bit f_* up from last run.
Nope Jail doesen't start.

Code: Select all

mountd[1781]: can't delete exports for /mnt/Daten/Jails/owncloud/dev: Invalid argument

I had this before I know how to get rid of it but I just mention it because it is caused by mountd as well as the other errors which saw before (but didn't save).


Now I want to know if it is me or my system and would be glad for any advice.

Flo

(BTW this isn't my first NA4free system and I am not completely new to the brig either)

I had got a similar problem with aMule: my mistake was the use of slim Jail instead of full jail. What kind of jail did you use?

[raulfg3]

A BSD limitation of nullfs is that all must reside in same disk.

if /mnt/SichereDaten and /mnt/Daten/ are two phisical disk or two diferent pools, nulls fs do not work.


you must in this case change location of your jail to reside in same pool that your data. eg:

Code: Select all

/mnt/Daten/Eigene_Musik /mnt/Daten/Jails/owncloud/mnt/Daten/aUser/files/Eigene_Musik nullfs rw 0 0

must work.

TheBrig's current configuration not allow to mount zfs dataset.

Is it possible now? I see the settings, but i can't get it to work...

In a fresh jail, what do i need to configure, to get for example /mnt/tank/test (zfs dataset on host) to be readable/writeable from inside the jail?
