Increasing Swap on RHEL

Resizing swap if you have local storage: swap LV name: lvol.swap root_VG name: VolGroup00 Take LV from 24 to 32GB: shut off swap: swapoff /dev/VolGroup00/lvol.swap extend LV: lvextend -L32G /dev/VolGroup00/lvol.swap make new swap: mkswap /dev/VolGroup00/lvol.swap (output should look like: Setting up swapspace version 1, size = 34359734 kB ) turn swap back on: swapon /dev/VolGroup00/lvol.swap double check with top or cat meminfo should show new swap size: Swap: 33554424k total, 0k used, 33554424k free Thanks & Regards Avinash Pillai  URL :  http://avinashpillai.blogspot.com Email: avinashp25[AT]gmail[DOT]com
