How To: Extend (Make it bigger) an ext3 formatted LVM partition

1. Extend the LV partition

lvextend –L +1GB /dev/vgroot/lvsrv

2. Adjust the filesystem (ext3) to the new size of the partition

ext2online /dev/vgroot/lvsrv

3. Occasionally you can tell the command ext2online how big the filesystem should be, the command above usually resizes the filesystem to use the full amount of the partition

ext2online /dev/vgroot/lvsrv 5G
