Jail cloning
jclone command
% cbsd jclone
% cbsd jrclone
Description:
Creates a clone of a given jail. The command requires the name of the original jail (passed with old) as well as a name for the clone, specified with new and a FQDN (hostname) with host_hostname. Optionally a new IP Address can be given with the ip4_addr parameter (multiple IPs need to be separated by commas).
Attention: Since 11.0.10 version, CBSD on ZFS-based hosters will be use ZFS clone features!
ZFS clone features is ultra fast operation (thanks to Copy-on-write), but imposes some restrictions - you will be dependent on the parent snapshot. If you try to remove parent environment, CBSD automatically executes the zfs promote command, but when you works with snapshot independently - just keep it in your mind
You can control this behaviour via clone_method= argument or, to set it globally, use rclone.conf and bclone.conf to overwrite settings from 'auto' to 'rsync':
% echo 'clone_method="rsync"' > ~cbsd/etc/rclone.conf % echo 'clone_method="rsync"' > ~cbsd/etc/bclone.confWhen ~cbsd/etc/bclone.conf (for bclone) and ~cbsd/etc/rclone.conf contain:
clone_method="rsync"Clone will not use zfs clone even on ZFS filesystem and you will get full copy via rsync
Example:
cloning jail jail2 to jail3 with changes ip address ip4_addr and name of hosts host_hostname:
% cbsd jclone old=jail2 new=jail3 host_hostname=jail3.my.domain ip4_addr=10.0.0.22/24
