Is it possible to increase the storage pool by adding more SSDs?

[Servnet Mexico]

How are you team, hope you are feeling well! I have a question, it turns out that I have a long time installation of a cluster with 3 nodes that hosts VMs in pool, however this pool is filling up and it is necessary to add more capacity to these.

My question is: Is it possible to add more space to this pool by adding a new ssd in each server with the same capacity?

I mean, put a 1.92TB ssd to each physical node to increase my pool capacity in 1.92TB.

Greetings!

Yes, sure. Same class (SSD or HDD) and same capacity on all nodes gives best and balanced performance.

If this screenshot represents the actual disks and only pve03 has SSDs then it's already unbalanced. (pve03 always has to wait for the other nodes)
No error, only slower speed overall.

Besides that you should update (v14 is old) and reboot one node after another. With newer versions more/enough disks per node and enough free capacity it's possible to move data from one disk to the others and in the end moving/pulling one disk physically to another node to balance it out. But that should not be done with nearly all disks full and only with enough experience!
