Hi all!
Quick one to resize swap online:
[root@server-db ~]# swapon -s Filename Type Size Used Priority /dev/mapper/rootvg-lvswap partition 5242872 373624 -1 [root@server-db ~]# vgs VG #PV #LV #SN Attr VSize VFree [...] rootvg 1 6 0 wz--n- 135.69G 5.69G [...] [root@server-db ~]# lvextend -L +2048M /dev/mapper/rootvg-lvswap Extending logical volume lvswap to 7.00 GB Logical volume lvswap successfully resized [root@server-db ~]# vgs VG #PV #LV #SN Attr VSize VFree [...] rootvg 1 6 0 wz--n- 135.69G 3.69G [...] [root@server-db ~]# mkswap /dev/mapper/rootvg-lvswap Setting up swapspace version 1, size = 7516188 kB [root@server-db ~]# swapoff /dev/mapper/rootvg-lvswap [root@server-db ~]# swapon /dev/mapper/rootvg-lvswap [root@server-db ~]# swapon -s Filename Type Size Used Priority /dev/mapper/rootvg-lvswap partition 7516188 373624 -1
See ya!

This is not “online” swap resizing… you can’t mkswap a partition currently in use:
mkswap: error: /dev/mapper/rootvg-lvswap is mounted; will not make swapspace
You have to swapoff; mkswap; swapon, and that’s not very “online”.
