Jan,
These are my comments. In general you design assumes lot of changes
in the orchestrator module. For example Orchestrator doesn't talk about
ZFS. Are you planning to update the orchestrator design document with
the changes?
Section 1: Assumptions
- The project assumes that ZFS root/boot is available. Can you add
the information whether it is already available or when it is expected
to be available?
- What is a basic environement? (The second bullet in the assumptions)
Section 2:
- What is a Manager Module (MM)? Is it same as TI manager? The name
sounds too generic. Can you change it to refer to the actual functionality?
Section 5.1.1:
- Design is spelled as desifn
Section 5.2:
- Are we planning to support creation of zfs pool across multiple
disks during installation?
- What is meant by "It is possible to install on unlabeled disks".
How do we determine whether the disk doesn't have a label or it has a
label we don't understand?
- I don't understand the third bullet "There should be possibility
of utilizing unallocated disk space when creating new Solaris
partition". Do you mean there will be an interface in MM to specify a
special keyword to use all free space?
- CLI tools fdisk and and Format can't be used from GUI. Why these
CLI tools are mentioned here?
- pfinstall and ttinstall manages fdisk partitions using the libspmi
libraries.
- I am not sure whether it is a good idea to create a label. We may
destroy the user data.
- Are you planning to use fdisk tool to create/modify fdisk table?
Why can't use the existing libspmi interfaces?
Section 5.3.1:
- Why install needs to create non-root ZFS pool?
Section 7:
- If I want to use the existing target (fdisk partition), do have to
use ti_target_create() from the orchestrator?
- What about deleting a partition?
That is all for now.
