I decided to try out the zfs rollback feature today. I halted my tomcat zone, and took a zfs snapshot of it like this:
myad...@baptist.ds:~# zoneadm -z tomcat halt myad...@baptist.ds:~# zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / ipkg shared 1 routerb2 running /zones/routerb2 ipkg excl 4 webphp4 running /zones/webphp4 ipkg excl 6 mysql running /zones/mysql ipkg excl 12 dovecot2 running /zones/dovecot2 ipkg excl 13 mail running /zones/mail ipkg excl 14 stamps running /zones/stamps ipkg excl - zone1 installed /zones/zone1 ipkg excl - tomcat installed /zones/tomcat ipkg excl - dovecot installed /zones/dovecot ipkg excl - zone2 installed /zones/zone2 ipkg excl myad...@baptist.ds:~# zfs snapshot rpool/zones/tomcat@2013-0308-1553 myad...@baptist.ds:~# zoneadm -z tomcat boot Then I logged into the zone with "zlogin -C tomcat". I did some work which created a bunch of files in /usr and /var. I didn't like how it worked out, so I logged out of the zone, exited the console, and then halted the zone. I did a zfs rollback to the snapshot I had just taken previously. myad...@baptist.ds:~# zoneadm -z tomcat halt myad...@baptist.ds:~# zfs rollback rpool/zones/tomcat@2013-0308-1553 cannot rollback to 'rpool/zones/tomcat@2013-0308-1553': more recent snapshots exist use '-r' to force deletion of the following snapshots: rpool/zones/tomcat@zfs-auto-snap_frequent-2013-03-08-16h01 myad...@baptist.ds:~# zfs rollback -r rpool/zones/tomcat@2013-0308-1553 myad...@baptist.ds:~# zoneadm -z tomcat boot myad...@baptist.ds:~# I booted the zone, and logged back into it.
