Disk usage

Hi

I have a 4 GB HDD and different filesystems like /, /stand,/home etc. All these filesystems consumed 2GB. How do i know how much free space available on disk using any command.

Use bdf:
$ bdf -l
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol4 204800 40330 154277 21% /
/dev/vg00/lvol1 127573 45019 69796 39% /stand
/dev/vg00/lvol9 1024000 481316 513435 48% /var
/dev/vg00/lvol8 1576960 802403 727215 52% /usr
/dev/vg00/lvol7 65536 5244 56561 8% /tmp
/dev/vg00/lvol6 1024000 282213 695460 29% /opt
/dev/vg00/lvol5 1024000 405126 580289 41% /home

It gives total, used and available for each file system.

Hi:

'bdf' reports used and free space on mounted filesystems.

If you want to know allocated and free space on a *physical* disk, use:

# pvdisplay /dev/dsk/cXtYdZ

For a volume group (at large) use:

# vgdisplay /dev/vgXX

Regards!

I will ususally look at the vg info i.e.

vgdisplay vgXX | grep -i Free
vgdisplay vgXX | grep -i Size

take the results of each and multiply.

so you may see 500 and 4, when multiplied would give your 2000MB or 2GB.

Hi,

As per JRF, we can find the free disk space.
Another method is by using SAM.
try to create a dummy logical volume (lvol), it shows the total disk space remaining

I misinterpreted your question, you need vgdisplay and pvdisplay, like James and Craig suggested.
