Disk space issue

kiran b jadhav — Thu, 25 Nov 2010 13:12:28 GMT

Hello Gurus,

My HPUX system (11.31 OS) is having 1 disk of 135GB in VG00 & Used space is 98GB. But i am getting only 8GB free space. The question is that where the ~25GB space has gone?

Have you removed any open files?

Hi Kiran

Can you please copy the vgdisplay output here? For me this looks like a issue with the maximum number of extends per physical volume value. i.e. PE/PV

If that is right , you may need to adjust the PE/PV value using vgmodify.

To proactively avoid this issue you can use
-s 32/64 M -e 3000 etc while creating vg itself.You can select the values depending of your PV size

-s extend size
-e No of PE/PV

To solve it now, you need to see the output of
#vgmodify -t vgname

This will show a table relating PE/PV and the maximum PV/VG value. Based on this table, need to modify it to appropriate value to use the full 135G disk.

Thanks & Regards
