Determine disk space in AIX

UNIX AIX

Hi

I need to extend a FS in AIX but Im not sure on how to calculate the free space

Please advise if my math is correct:

-------PP SIZE:        64 megabyte(s)
--------TOTAL PPs:      1086 (69504 megabytes)

so the total size of volume is 64 * 1086 = 69504 MB (695GB)

Free PP is-- FREE PPs: 176 (11264 megabytes)
so I have free space of 176* 1086 = 191136MB (191 GB)

or is it Free PP * PP Size = 176 (11264 megabytes) * 64 megabyte(s) = 11264MB (112 GB)

Heres my rootvg output:>

$ lsvg rootvg
VOLUME GROUP:       rootvg                   VG IDENTIFIER:  00c49eaa00004c000000010710cbda94
VG STATE:           active                   PP SIZE:        64 megabyte(s)
VG PERMISSION:      read/write               TOTAL PPs:      1086 (69504 megabytes)
MAX LVs:            256                      FREE PPs:       176 (11264 megabytes)
LVs:                12                       USED PPs:       910 (58240 megabytes)
OPEN LVs:           11                       QUORUM:         1 (Disabled)
TOTAL PVs:          2                        VG DESCRIPTORS: 3
STALE PVs:          0                        STALE PPs:      0
ACTIVE PVs:         2                        AUTO ON:        yes
MAX PPs per VG:     32512                                     
MAX PPs per PV:     1016                     MAX PVs:        32
LTG size (Dynamic): 256 kilobyte(s)          AUTO SYNC:      no
HOT SPARE:          no                       BB POLICY:      relocatable

in the future I would post a question like this in the AIX forum.

it reads exactly as you see in lsvg output. ~11GB

176 (11264 megabytes) FREE PP*PP SIZE

keep in mind when you add space to a file system it will be done in 64MB chucks. for example if you needed to add 100MB to a file system you will actually add 128MB or 2xPP.

AIX is part of unix too

Thanks alot, I was a bit confused there. I got my LUN allocation already, going to extend the FS now. Thanks alot...appreciate ur help

your welcome.

This question is not really a "UNIX for Dummies Questions & Answer" question. There are several sub-forums on unix.com -- include AIX. That is what I meant about posting the question to the AIX forum.
