make_tape_recovery resizes a file system ??

[Mladen Despic]

My /dev/vg00/lvol5, mounted under /opt, has 420Mb.
I create a recovery tape by using:

make_tape_recovery -B /var/opt/ignite/uxinstlf.recovery -x inc_entire=vg00 -v -a /dev/rmt/0mn

but when I recreate the system (non-interactively, on the same hardware), my /dev/vg00/lvol5 has 464Mb.

I expected the identical file systems after the recreate
process. Why is it not doing so? Is there a minimum
size for /opt, perhaps?

I'm using Ignite A.3.3.116 on HP-UX 10.20.

It should be same size.

When you say 420MB and 464 Mb, it is from bdf or from lvdisplay ?

See /var/opt/ignite/recovery/config.recover for LV sizes.

Hi,
I agree with Carlos.
Maybe, just maybe, an earlier attempt was made to increase this filesystem. Lvextend was done successfully; and extendfs failed because filesystem was in use!? Just a wild guess.

Hi:

Interesting. Here's another WAG. I've noticed on some interactive recoveries that some of the default filesystem sizes are offered as a percentage of the volume size as opposed to a static value. I believe /opt was one of them.

Hi,

James is in fact correct, when you do a cold install /opt is one of the
volumes that does not use "fixed Mb", it does use a percentage
of the remaining space on the selected installation disk by default.
You will most likey find that /usr is in the same boat.

Just my 2 cents worth.

[Mladen Despic]

The size is from lvdisplay (not bdf).
/var/opt/ignite/recovery/config.recover shows 420Mb.

James, it looks like you may be pointing in the right direction. In fact, Michael's confirmation agrees with
a similar (earlier) observation for /usr on one of our systems.

One of our sys. admins may be doing another test with /opt at 420Mb, but more free disk space. I will let you know if the test confirms what you are suggesting. Thanks ...

Hi Mladen:

My observations stem from a couple of recent cold installs of 11.0 using the November 1999 Core CD. In reconstructing a 10.20 system from a 'make_tape_recovery tape', at a remote diaster recovery (DR) site (with Ignite 3.2), I can't recall what defaults were offered. I did the recovery interactively and chose to specify vg00 filesystem sizes based upon generalized standards I am defining for my systems and the DR plan.
