ZFS and Containers
July 13, 2007 – 2:33 pm
Upside: good granular resource management. efficient disk usage.
Downside: one Solaris kernel. shared ethernet interfaces.
Solaris Containers ( = Zones plus Resource Management) and ZFS is pure joy, especially the ability to clone zones to save disk space. There is a bit of a gotcha though. As Solaris hasn’t got boot support for ZFS yet, there is an issue in that you cant upgrade a zone if its root is sitting on a ZFS volume. I hear that the next release of Solaris (07/07?) will have ZFS boot support and will fix this issue. Solaris Internals has lots of great info.
