Hi guys , thanks for the response. You mean that both partitions are usefulls and are needed. Mi concern is to create a layout at the install moment and after some time realize that some partition is too big ot to small. So , my idea is: Designate 1Tb for LVM. Designate 2TB for LVM-thin. Left 2TB for future use:
So, In the future is it possible to modify partitions size without any risk? Other: Can I add a Raid 1 with 2 ssd hard disk on remaining empty slots later or do I need to have them installed at the proxmox install moment? Thanks!!!! Leandro.
