Re: Migration of Jail from one host to another?
Quoting "Scott Lambert" <[EMAIL PROTECTED]> (from Wed, 2 Jul 2008 15:22:35 -0500): I'm probably doing this completely wrong. I setup a couple of jails using simple image files because I thought that would make migration to another server more straightforward. I am now trying to migrate my first jail. A little bit late, but I moved 2 ezjails today (on 8-current). It was setup inside a ZFS, not in an image. It worked without problems (I transferred the ZFS data (zfs send | zfs receive), the fstab file, and the ezjail config file). /usr/local/etc/rc.d/ezjail.sh start ezjailConfiguring jails:. Starting jails: testnetmount: /home/ezjails/migrate.jail.device : Operation not permitted You have a problem here. You may want to look into ezjail what the testnetmount is doing. I assume there's some problem with creating the md device. df: /home/ezjails/migrate.jail/dev: No such file or directory mount: /home/ezjails/migrate.jail/dev: No such file or directory I think this and the rest are followup errors of the failed mount of the disk image.

Migration of Jail from one host to another?
I'm probably doing this completely wrong. I setup a couple of jails using simple image files because I thought that would make migration to another server more straightforward. I am now trying to migrate my first jail. I am using the ezjail tools for creating and maintaining jails. The existing jail host is 6.2-STABLE FreeBSD 6.2-STABLE #1: Sun Mar 11 21:46:01 CDT 2007, ezjail-2.0.1. The new jail host is 7.0-STABLE FreeBSD 7.0-STABLE #0: Sat May 10 06:29:00 CDT 2008, ezjail-2.1. I have created a test jail on the 7.0-STABLE box with ezjail-admin which works perfectly, using what I believe were the exact same parameters given, other than IP/hostname, when I created the 6.2-STABLE jail. # ezjail-admin create -i -s 1G test 192.168.8.237 I have moved over the fstab.migrate_jail file, and the /u/l/e/ezjail/migrate_jail config file for the 6.2-STABLE jail to the 7.0-STABLE box and created an empty directory beside the 7.0 test jail's empty directory. I shut down the jail on the 6.2-STABLE host and scp'd the image file to the 7.0-STABLE box. I put it beside the empty jail directory. I made sure the fstab.test and the fstab.migrate_jail look the same except for jail name changes. I made sure the /u/l/e/ezjail/test and /u/l/e/ezjail/migrate_jail files look the same except for jail name changes. # more /etc/fstab.test /home/ezjails/test.device /home/ezjails/test ufs rw 0 0 /home/ezjails/basejail /home/ezjails/test/basejail nullfs ro 0 0 # more /etc/fstab.migrate_jail /home/ezjails/migrate.jail.device /home/ezjails/migrate.jail ufs rw 0 0 /home/ezjails/basejail /home/ezjails/migrate.jail/basejail nullfs ro 0 0 # more test_tcworks_net export jail_test_hostname="test" export jail_test_ip="192.168.8.237" export jail_test_rootdir="/home/ezjails/test" export jail_test_exec="/bin/sh /etc/rc" export jail_test_mount_enable="YES" export jail_test_devfs_enable="YES" export jail_test_devfs_ruleset="devfsrules_jail" export jail_test_procfs_enable="YES" export jail_test_fdescfs_enable="YES" export jail_test_image="/home/ezjails/test.img" export jail_test_imagetype="simple" export jail_test_attachparams="" export jail_test_attachblocking="" export jail_test_forceblocking="" # more migrate_jail export jail_migrate_jail_hostname="migrate.jail" export jail_migrate_jail_ip="192.168.8.238" export jail_migrate_jail_rootdir="/home/ezjails/migrate.jail" export jail_migrate_jail_exec="/bin/sh /etc/rc" export jail_migrate_jail_mount_enable="YES" export jail_migrate_jail_devfs_enable="YES" export jail_migrate_jail_devfs_ruleset="devfsrules_jail" export jail_migrate_jail_procfs_enable="YES" export jail_migrate_jail_fdescfs_enable="YES" export jail_migrate_jail_image="/home/ezjails/migrate.jail.img" export jail_migrate_jail_imagetype="simple" export jail_migrate_jail_attachparams="" export jail_migrate_jail_attachblocking="" export jail_migrate_jail_forceblocking="" 14:35:33 Wed Jul 02 # egrep -v '^(#|$)' ../ezjail.conf ezjail_jaildir=/home/ezjails /usr/local/etc/rc.d/ezjail.sh start ezjailConfiguring jails:.
