I'm trying to configure LSM on DU 4.0d. We received the system pre-installed,
with the root filesystems configured as ADVFS filesystems.
I've been mucking about with LSM all morning, had it configured so that
root and swap were encapsulated and mirrored, and was trying to mirror
/usr and /usr/local to the same mirror disk that swap and / used.
I've used SEVM on suns, so have some familiarity with this, but am finding
that the DEC implementation does not work as expected.
Oddity:
* Rather than taking my target disk as the mirror disk and also as
a logical disk, and carving out pieces to be used to mirror / and
swap, LSM appears to create volumes out of partitions, so that I end
up with LSM disks entitled "rz16d" and "rz16g". Under Solaris,
the entire disk is incorporated as an LVM logical disk, and then
subdisks are put on partitions.
Problem/oddity:
* after finding that I couldn't mirror all of disk A to disk B because
evidently disk A partitions use all available space, and since disk B
is the same size as disk A, and evidently LSM wants partitions to
mirror to that are slightly bigger than the original partitions, I
tried dismantling the entire structure, using volunroot, etc. I'm
left with an LSM config with one LSM disk called "rz16d" which I
can't remove, as the system thinks it is the last volume in LSM
and that you can't remove that last volume.
Can someone tell me:
a. How to release "rz16d" so I can start all over again?
b. How to mirror rz16, which contains:
/, /usr, /usr/local, swap
which filesystems use all available blocks on rz16, to the
identically sized empty disk rz9?
Many TIA!
