Import a Jail

[mewhalen]

I used "warden export <jail> to export a jail from a FreeNAS box, which was successful. I then ran "warden import <jail> to import the jail to a new FreeNAS box. When I attempt to set the IP on the imported jail, I receive the following;

I'm unable to export/import jails via warden as well.

Jails appear to successfully export via the warden export jailname command, however subsequent import attempts fail like so:

# warden import freshjail.wdn
/usr/local/share/warden/scripts/backend/importjail.sh: cannot open freshjail.header : No such file or directory
ERROR: Specified file is a incompatiable .wdn file!

I had this same problem and the issues are actually with the script. Not the file itself. The do-while loop that goes through the header file has an extra space.

Code:

done < "$HEADER "  
 
     vs.

done < "$HEADER"

So it says no such file when it really is trying to read a file with an extra space character at the end.

The other thing since my JAILS are using DHCP with static maps based on mac address, it yelled at my second import for using the same "DHCP/" ip address. So I just cut that code block out of the script since I knew mine were ok. I did have to open each via the web interface uncheck/recheck DHCP again though to get the settings to something other than OFF.

Finally, once loaded it got the "multiple ID's found" type of query error. For some reason the script to assign a unique id wasn't working either. I didn't debug that...i just went into the .JAIL_NAME.meta directory and updated the 'id' file to make them all unique.

This was extremely helpful for me. Specifically I fixed line 141, and commented out lines 43-64, and 159-198 of /usr/local/share/warden/scripts/backend/importjail.sh. For ease of finding an empty id, I just catted all the ids with cat /mnt/MEDIA/jails/.*.meta/id

Edit: after further playing, I would not recommend commenting out a bunch of the code like I did. There seems to be some erratic behavior. The line 141 fix is straightforward and makes sense, but I've had hit and misses for imports.
