Azure VM Standard BS1 mods, swap and lvm

 The azure Azure VM Standard BS1 has 65GB of hard disk for the operative system. But there is an issue with redhat running on 1GB, it crashes, and the other one is that lvm doesn't leverage the space.

The solution create a swap and extend the lvm!

 

Creation of swap

fallocate -l 3G /swap-file
chmod 600 /swap-file
mkswap /swap-file
swapon /swap-file
swapon --show
cp /etc/fstab /etc/fstab.bak
echo '/swap-file none swap sw 0 0' | sudo tee -a /etc/fstab

 

Check the lsblk and extend the partition

lsblk

lvextend --size +10GB --resizefs /dev/rootvg/rootlv

df -h
