Hi guys.
I have a very old proxmox version (4.X).
There I have only one partition where I store both vms and isos images.
Now, I installed pve last version.
Did you reinstall your server? You can update. It's really easy - see
the wiki.
After install default process finished I can see two partitions created.
(LVM and LVM-thin)
The main difference (on a single server) between LVM and LVM-thin in
proxmox is that you can't use snapshots with "normal" LVM volumes. You
have to use LVM-Thin.
After reading in storage documentation , it is not clear for me what the
difference is between them.
Can I use only one partition (like in my old proxmox ver4) ?
Proxmox uses LVM is a blocklevel storage. You can't use is for files
directly (https://pve.proxmox.com/pve-docs/chapter-pvesm.html). So you
need another partition/LVM Volume with a filesystem for your ISOs. LVM
is really flexible. You can create a logical volume with a filesystem
with the shell and mount it to use it for ISOs, Backup or whatever.
Any advice regarding storage layout good practice would be appreciated.
Depends on your usage. If possible do some fio tests with different RAID
levels, stripe sizes, cache settings...
Currently I have a 5TB Raid5 storage available.
Regards,
Leandro.
