I am trying to upgrade my laptop hard drive, and want to use Live-upgrade.
What I have done so far is:
1. Moved the old drive to an external enclosure
2. Made it bootable (At this point I had to overcome the first obstacle -
due to ZFS storing the disk device path in the ZFS structure it refused to
automatically mount the root file system. The work-around involved booting
to safe mode and mounting the zfs file systems, then rebooting. Note
previously I had to re-do this even when moving the disk from one USB port
to another. The disk is now portable at least between USB ports, seemingly
after zpool upgrade to v11)
3. Installed the new drive into the laptop.
4. Partitioned it using Solaris/fdisk. Oops.
At this point I had to overcome the second obstacle - the system failed to
find the root pool. The eventual solution (work arround) was to boot from a
live CD and wipe the partition table from the internal disk.
5. Trying to create a partition table on the disk again resulted in format
telling me the disk type is unknown. A partial work-arround was to
temporarily put the whole disk under zfs control and then destroying the
pool. This resulted in an EFI label being created on the disk. From here
it was possible to delete the EFI partition and create new partitions, but
Solaris does not properly recognize the primary partitions created.
The desired outcome of the partitioning is:
fdisk P1 = Solaris2 (oxbf) to be used as ZFS root
fdisk P2 = XXXX (to be used as ZFS data pool)
fdisk P3 = NTFS... Still debating whether I want to have a copy of Windows
consuming disk space... I still have to finish Far Cry some time.
fdisk P4 = Extended partition, will be sub-partitioned for Linux.
The best I''ve been able to do so far is to use Linux to create P1 and
P2
above with neither made active. If either is made active, I can no longer
boot from the external disk (grub fails to find the root).
But Linux did not properly create the partition table.

Going to the partition menu, I try to create a Slice 0 of the entire disk:

This has got me stumped.
1. Why does it create a slice zero spanning the entire physical disk, in
stead of just the entire Soalris fdisk partition?
2. Why does Slice 2 not get created?
3. How do I get the Slice 8 and Slice 9 fixed (to blank out the bootblock
and set up the alternatives/defects list)
Note: I had this problem before using Linux to partition the disk.
My planned next steps are (hopefully)
Fix the partition table
n1) Create data zpool in p2 slice
n2) Boot linux and run Linux installer to allow it to create logical
partitions in EXT partition and set up grub menu.
n3) Copy grub menu entries to somewhere else for future reference
n4) Boot back into Solaris
n5) Create zpool on new disk P1 (Entire Solaris2 partition)
n6) Run live upgrade to set up new BE on the new zpool
n7) luactivate and reboot.
n8) Add Entries for Linux to Grub and test.
I expect to have several problems during this procedure. For example, the
seemingly simple step n1 above currently fails, most likely due to the
partitioning on the disk being screwed up as it stands.
I am stuck at Item nr 5 - I need to get the partition table on the new disk
sorted out. Any help would be appreciated!
