Tru64 LSM

Hi there!
   Thanks for the reply!

   I'm using AdvFS.  You just mean that the partitions don't actually have to conform to any specific convention, right? The AdvFs domains still get defined on disk partitions, if you look at the symlinks in /etc/fdmns/<domain_name>.  
   You can put a symlink to a LSM volume in there too, but the problem I'm running into is that the installer (text-based, because I don't have a graphics card) is fairly insistent upon applying a disklabel that it calculates as barely sufficient to hold the stuff you're trying to install, and wants to use 'a' for boot, 'b' for swap, 'd' for the LSM private partition, and so on and so forth.  I'll probably have to resort to setting it up without LSM, then encapsulating it, but again that wouldn't lead to a "sliced" LSM disk.  (I think)

   Might you be so kind as to show the ls -la from your /etc/fdmns/*/, and the disklabel -r dskX from the disks?

   The documentation suggests that come extra flexibility could be gained by doing a graphical install.

I wish I could help you with that but I can't.

But I can talk about partitions, if you are using the advanced file system
then none of the partition rules apply, if you are using the ufs then
the traditional layout is this:

    a - boot partition, mounted as /
        unlike linux, there is generally no /boot partition
    b - swap partition
    c - the entire disk
    d to g - partitions for other stuff like /var /usr /tmp etc.

I have a pair of Alphaservers running Tru64 Unix in a cluster and it boots
from a raid set delivered by a RA8000 SAN and three Alphaservers who boot
off local storage using a mirror set delivered by a KZPSC (DAC960) or one
of its various similar siblings.  In all cases the file system is Advfs
which looks a lot like the LSM with volume groups and logical volumes etc.
Here is a df of the system partitions from one of the systems:

    Filesystem         512-blocks  Used     Available  Capacity  Mounted on
    root_domain#root    2097152     327726  1748880    16%       /
    usr_domain#usr      8388608    3829826  4517680    46%       /usr
    var_domain#var      8388608     715100  7579952     9%       /var
    local_domain#local 16146432    8941490  6955808    57%       /usr/local

As with you, it has been a long time since I looked closely at any of this.
I didn't understand the difference until I started looking at the
configuration when I went to answer your question.  We haven't used the LSM
in years.
