[OpenIndiana-discuss] Question about halting a zone

[Mark Creamer]

I was reading about how to update non-global zones, and found a
Solaris document which says the following:

1. Update the Global Zone
2. Reboot
3. Halt the non-global zone   (zoneadm -z myzone halt)
4. Detach the zone  (zoneadm -z myzone detach)
5. Re-attach the zone with -u  (zoneadm -z myzone attach -u)

In my testing, this seems to go fine. My question is, what happens
when you halt a zone - for example, if MySQL is running on that
non-global zone, should you stop it first before halting the zone to
avoid the risk of corrupting data? Or is a halt safe without stopping
any running services first?

Thanks
