command for size disk

[Eli Daniel]

Hello,

There is a command to determine the size available or used in a disk of a VG?

Shalom,

vgdisplay # shows free PE and size of each PE in a volume group.This shows what portion of a VG is part of a logical volume.

pvdisplay # will show on a physical volume free versus allocated PE's and these figure can be translated into MB or GB

thanks steven,

in this case disk free size 3.9 GB???

--- Physical volumes ---
PV Name /dev/dsk/c27t1d4
VG Name /dev/vgQAECC
PV Status available
Allocatable yes
VGDA 2
Cur LV 10
PE Size (Mbytes) 4
Total PE 15359
Free PE 1021
Allocated PE 14338
Stale PE 0
IO Timeout (Seconds) default
Autoswitch On
Proactive Polling On

(1) # vgdisplay

will list all vg , to get the total/ used / free size in vg

total = PE size * Total PE
used = PE size * Alloc PE
free = PE size * Free PE

(2) And to check how many disk in vg

#vgdisplay -v /dev/vgname

Daniel,

- There is no single command , but you can try this, for: Total,Allocated and Available space on the VG:


# vgdisplay vg_name | grep -e "PE Size" -e "Total PE" -e "Alloc PE" -e "Free PE" | cut -c 25- | xargs | awk '{print "Total =\t"$1 * $2 "MB\n" "Allocated =\t" $1*$3 "MB\n" "Free =\t" $1*$4 "MB" }'| awk '{printf "%-15s%-2s%s\n",$1,$2,$3}'



Output:
Total = 138208MB
Allocated = 131072MB
Free = 7136MB

Hi,
As everyone post above "vgdisplay" is the command.
for more information on vgdisplay check the man pages.

When disks are added in VG, they lose there identity(from storage point of view) it becomes the pool a disk area for VG,
You can see the free space from vgdisplay command
(Free PE*PE Size)/1024 GB.
