HAQBAHU — Sun, 05 Apr 2009 04:32:46 GMT

i have created a physical volume, then add this physical volume in existing volume group. Then i have extended a logical volume in this volume group by adding the 9GB space in it. This volume group is a SWAP vol grp. It is showing the new size after adding space but on OS level when i see the swap space usinf "free" command it is showing the old swap size. please help.........regards.....Adeel

Did you try the following:
swapoff
mkswap
swapon

HAQBAHU,

After creating new swap space as mentioned above (mkswap etc), you will have to add to /etc/fstab (this will ensure it is available next reboot), then swapon -a.

swapon -s will show mounted swap files.
