[fixed]unable to move jails to another pool/disk

[nikkon]

Hi all,

I am running out of space on my initial jails pool and I am trying to transfer all jails to a bigger Pool/Drive
I tried using the zfs snapshot and then zfs send / receive for this.
There is something I am missing as I can't create the snapshot:
Current jails pool:

created snapshot

zfs snapshot Jails/iocage/jails@test1-snap

snapshot created:
zfs list -t snapshot | grep test1-snap
Jails/iocage/jails@test1-snap 0B - 136K -

send the snapshot to the new pool called Jail

zfs send -R Jails/iocage/jails@test1-snap | zfs receive -v -F Jail
cannot send Jails/iocage/jails@test1-snap recursively: snapshot Jails/iocage/jails/coruscant@test1-snap does not exist
warning: cannot send 'Jails/iocage/jails@test1-snap': backup failed
cannot receive: failed to read from stream

What am I missing?
thank you

 

[nikkon]

my bad. I was missing the bkp name. I fixed it by changing zfs send Jails/iocage/jails@test1-snap with Jails@test1-snap

can be closed or deleted. problem fixed.

I'd like to add a step-by-step guide that help me to do that. I it found over at lawrencesystems.com

FREENAS : move iocage Jails to another pool

Well, I bit the bullet and finally figured it out, with some trial and error. I wanted to move jails from bluePool to ssdPool logged out from the UI (don’t know if it played a part, thought to be safe) iocage stop ALL zfs unmount -f bluePool/iocage zfs snapshot -r bluePool/iocage@migration...

I wanted to move jails from bluePool to ssdPool

• logged out from the UI (don’t know if it played a part, thought to be safe)
• iocage stop ALL
• zfs unmount -f bluePool/iocage
• zfs snapshot -r bluePool/iocage@migration
• zfs send -R bluePool/iocage@migration | zfs receive -v ssdPool/iocage
• iocage clean -a
• zfs destroy -rf bluePool/iocage
• iocage activate ssdPool
• zfs destroy -r ssdPool/iocage@migration
• zfs set mountpoint=none ssdPool/iocage/download
• zfs set mountpoint=/ssdPool/iocage/download ssdPool/iocage/download

Last couple of commands were needed because when I issued
iocage list
I got
Please set a mountpoint on ssdPool/iocage/download
and I could not set the mountpoint just using the second command, I had to clean it up first (can’t tell if it was “locked” somehow by the previous setup, don’t know that much about FreeBSD).


Then I had to manually edit all the fstab for my jails
iocage fstab -e jail_name
and replace bluePool/iocage with ssdPool/iocage


That’s all. I logged in to the UI, started my jails/plugins and everything worked fine.
