Re: vHMC disk size

Thank you. Output looks much like the command they had already given me.

As to size of the disk, IBMs favorite answer: "it depends" Do you want to
mount DVD images, how many versions of update files you keep, how long your
log file retention is.......

I like 600 myself, although the above example is a mirrored drive on my
P8.

It's recommended that your vHMC be at least 500GB.
My question is: If it needs to be 500GB do you need to create it
bigger to actually get 500GB of usable space?
PC guy who generated it says he made it 500GB. However when I take
monhmc -r disk
and add up the file spaces I get 449458104 1k blocks or ~450GB
Or is there just a better way to see how much disk I have?

As the HMC seems to be *nix'ish (i've never used one, only going on
what I've seen on here)... you might find that "df" works and if it
does then "df -h" for the human readable format and "df -H" for the
same but in si units (powers of 1000's)

My guess is that 500GB was created and that is obviously less when
reported in GiB units.

As an aside note: My biggest linux annoyance is carefully setting up
partitions to make best use of sizes when mapped to raid arrays (to get
stripes and blocks and stuff all nicely lined up) and then have to do
it all over again via a live version of debian as the installer works
in GB units not GiB. I have to do it so rarely that by the time it
comes around again, I've forgotten the installers partition management
is in the wrong units.
