I have inherited this machine with following partition setup:
The machine runs Ubuntu 20.046 LTS and as one can see above there is 3.5T space unallocated in the partition schema. The unallocated space corresponds with separated drive. I would like to use the extra 3.5T to extend ubuntu-vg-ubuntu-lv
.
I've read through some material online (e.g. this, this, this). However since I do not have much experience in this kind of work plus there is no data backup mechanism in place I do not feel confident enough with any of the solution provided above.
I'd appreciated any advice how to (relatively) safely proceed with this.
