When resizing disks, here are the commands for each respected file system.
For xfs:
xfs_growfs /dev/vgname/lgname |
For ext 2/3/4:
resize2fs /dev/vgname/lgname |

Extending a LVM logical volume can be tricky. Extending a physical volume especially a boot drive is even more challenging. To make things simple, you can just easily add a new physical disk to your physical volume group. Here are the steps:
# add disk to your instance. fdisk /dev/sdh pvcreate /dev/sdh1 vgextend system /dev/sdh1 lvextend -l +100%FREE /dev/system/opt resize2fs /dev/system/opt |
# add disk to your instance. fdisk /dev/sdh pvcreate /dev/sdh1 vgextend system /dev/sdh1 lvextend -l +100%FREE /dev/system/opt resize2fs /dev/system/opt
The fdisk command requires a few steps inside such as creating a new partition, changing the partition to type to “8e” which is Linux LVM, and then writing your changes to disk.
The rest are pretty much self explanatory. It’s about creating a physical volume, extending the volume group, extending the logical volume, and then finally resizing the file system.
I recently started using Linux Mint again. Although it contains many excellent apps, there are a few things that are missing. So, here’s a list of programs that I have installed ✅ or will be installing on Linux Mint in the near future.
