Hi, indestructible_zoneroot is a feature, which shall prevent any accidental deletion of the VM. It is implemented by creaating a snapshot called “indestructible” and is held, which causes any deletetion attempts to fail. /checkpont is a place where all snapshots related to the zone get mounted as lofs. There is a difference in handling of these in SmartOS and in SDC:
In SDC, there is a components in system, which automounts these snapshots when they are created. In SmartOS, snapshost is created, but not automatically mounted. When you reboot the zone, the actual list of snapshots is fetched and lofs-mounted into the /checkpoint. If you create snapshot later, it won’t appear under /checkpoint until you reboot the zone. The readonly filesystem error you saw is caused by the fact, that lofs mount is read-only. If you want to get rid of it either delete zones/<uuid>@indestructible snapshot or run “vmadm update <uuid> indestructible_zoneroot=false” and it should remove the snapshot.
