Moving jails?

[maglin]

Sorry for this maybe simple question but I can't find my answer.

I built a test pool and built my jails on that. I have a single jail with plex, SabNZB, couch potato, headphonz, and 5 other things running correctly that took me some time to run properly. I have taken a snapshot of the jail and it resides on my production array. I would like to destroy my current test RAIDz1 pool and rebuild it as a stripped mirror.

Is it as simple as building the pool and restoring the snapshot and then configure the jail root to the restored snapshot? I plan to do this tonight when I get home from work.

I want to thank the main people on this forum that help everyone as I have been able to just search and find my answers. Thank you.

You can use the zfs send / recv commands to duplicate the jails dataset to another pool. However, consider that unsupported from a FreeNAS point of view. The best way is to backup the data in your plugins/jails and re-create them on the new pool.

i am trying to do this as well - from /mnt/Storage to /mntWorking.

if the best way is to backup the data in the jail can somebody please explain the process - is it done on the server or a client ?
is it done in a shell, gui or in a file explorer ?

thank you

Most of us are comfortable in command line, and use that over anything else for stuff like that.

 

[ethereal]

which command is required?

Someone recently posted a step by step on how to move jails (to an SSD pool I believe).

EDIT: Here's the post I was thinking of

Are people aware of the 'warden' command for managing jails? I didn't have success with the snapshot-copy method to move a jail, but below worked.

Do this for each of your jails to stop and export to myjail.wdn in the current jail root.
warden stop myjail
warden export myjail

Change jail root in FreeNAS settings, then import each jail. Had to include 'host' so that it would name the jail correctly otherwise it was named 'OFF'
warden import myjail.wdn --host=myjail

is this the way to go?

This may work but it is really slow.

it did move my jail (mysql) but it left behind other folders. in the end i deleted the jail and redid it from scratch.

I was not aware of using warden to move jails. I did get mine moved using

Code:

zfs snapshot -r /pool/dataset@copy

zfs send -Rv /pool/dataset@copy | zfs receive -Fv /destpool/dataset

It didn't work at first because when I created the jail my understanding of FreeNAS was infantile and I didn't know that what looked like a premade dataset was not really the best to use for my jail root. I used that top level dataset and FreeNAS created a new jail dataset, but the template for the jail was put into the top level dataset. Because of this I had to move the top level dataset to move the pool since the pool is using the standard jail template that was not located on the jails dataset. I was getting some origin error when trying to move the dataset. ie..

/pool
/pooldataset <--- folder I set for jails and the template was in
/jail <--- The jail I want to move

I should have just made another dataset to set as the jail root in the jail configuration page. This would make it easier to move all jails using zfs commands which btw was fairly fast. I would be somewhat nice to have this information put into the docs for building pools.

So, did your attempt to move your jail fail and you had to recreate it?

I am looking to move my jails to a whole different system and I am looking for advice that is correct to the FreeNAS implementation.

I was reading some possible solutions on the FreeBSD forum, but I was not sure that it would be the correct thing to do in FreeNAS.
