This is how my 2 TB (GPT) hard disk looks like
sda1 1 MiB Bios_boot sda2 1024 GB LVM --- vg1 1024 GB --- lv1 24 GB ext4 lv2 1000 GB ext4 800 GB unallocated sda3 200 GB ext4
What is the safest or better way to add 512 GB to lv2 ?
- Resize sda2 to be 512 GB bigger with parted or gdisk and then pvresize, lvresize, resize2fs.
- Create a new partition in the unallocated space, initialize it as a new pv and add it to the vg, then lvresize, resize2fs.
What's the best alternative? Are there performance penalties if the 2nd option is used?
