Is it possible to do a "live migration" with a Solaris Container running on HAStoragePlus ZFS (or any other filesystem for that matter)? I'm a bit fuzzy as to what kind of support Cluster 3.2 now offers for Solaris Containers.
Specifically something we would like to try at our site is HA-AFS using Sun Cluster and ZFS. Does anyone have any experience with this?
Please have a look at
http://docs.sun.com/app/docs/doc/819-2969/6n57kl13t?a=view
for a general explanation about Container and SC 3.2.
In a nutshell you can have both coexistant - failover Container and Container as virtual cluster nodes acting as resource group receivers.
If you say "live migration" - do you mean freezing the state of a Container (including running processes), moving it to a different node and continue running from the frozen state?
No, this is not possible as of today.
The failover of a Container is possible, but the zone will go through stop/start.
All this is not depending on the file system used. UFS and ZFS work as Container zoepath - but note that with ZFS currently live upgrade is not supported with Zones.
I have no experience with HA-AFS. Does AFS work in Zones?

Thanks for the link.
Hopefully live migration is somewhere on the roadmap; it would be a nice feature to have.
I think AFS server will work in zones, although I have not tried it yet. Reportedly the client has to be loopback mounted from the global zone though.
Thanks again for your help!
