One of my customers would like to upgrade from Digital UNIX 3.2x to 4.0, but the root partition is too small. The obvious steps are: back everything up unmirror the root disk unencapsulate the root disk back up root move the top of the root partition (a) up into the b partition, and adjust b accordingly create new filesystem on root, restore root, encapsulate, mirror The catch is that the LSM database is in a partition (h) between a and b, which makes expanding the a partition a bit awkward. So, how can we move the h partition so we can expand the a partition? (One other possible catch: the two root disk mirrors are the only ones in rootdg.) PJDM

Are you sure that the 'h' partition is physically between the 'a' and
'b' partitions? To the best of my knowlege LSM root encapsulations
have always stolen space from the end of the swap partition. If your
boot disk has 'h' in between 'a' and 'b' then you have a little more
work cut out for you but it can be done. You just need to back up the
'h' partition (using dd), rearrange the disklabel to your liking, and
then restore it. LSM must not be running while you are doing this so
it has to be after you unencapsulate root. Good luck.

h is definitely between a and b. I thought about dding h and restoring it to h in another place on the disk, but I wasn't sure if there was anything else involved. PJDM | |||||

Well, DD might work but you need to be aware of two things. One is
that in addition to restoring the contents of the H partition you also
need to restore the fstype field in the disklabel. Secondly, you can't
move or change an open partition so you can't muck with H while LSM is
running. You will either need to move the disk to another system to
edit the disklabel or boot from another disk. Lastly, it might be
easier just to remove the H partition from LSM control, edit the disk
label, and then place the H partition back under LSM control. In this
case LSM will handle the data. This assumes that you have multiple
private regions available to allow removing this H partition.
