Hi,
Sorry if this has been raised before.
Question: IS it possible to
1. Solaris 10 OS partitons to be SDS and have a single partition on that same
disk (without SDS) to be ZFS slice.
Yes.
2. Partition the zfs slice for many
partitions and each partition to hold a zone. Idea is to create many non-global
zones and each zone to be in a zfs partition.
I am not aware of the word "partition" in ZFS parlance, but I think I know what
you mean, so I will attempt to answer with my interpretation:
You can use a disk slice as a device in a ZFS pool. In that pool you can create
one or more ZFS filesystems.
A zone's root directory could be installed in a ZFS filesystem, but this is not
yet recommended, nor is it supported, because it is not yet possible to apply a
Solaris update to a system configured like that. This will be fixed.
If you don't care about that limitation, you can put one or more zones in a ZFS
fs. The best method seems to be one zone per ZFS fs. I think that's what you
were asking about. That model allows you to put a disk quota on a zone.
You can accomplish that same goal with SDS (now called SVM) and soft partitions,
but you wouldn't get all of the ZFS magic. :-)
3. Also, at a later date to
increase the zfs partitions used for zones as and when required.
Yes.
