Hello All. New to proxmox. Few ? about storage not pertaining ext4

[amb7247]

So where is what I have, I have a couple of good condition 500GB SSD. I know i don't want to use ZFS these due to the masstive amount of writes that ZFS can introduce to consumer drives and how they can wear them down quickly. So due to these being consumer level ssd's I I want to for now stick with ext4.

So, I have a few other ideas and best practice with using ext4 instead of ZFS.

Main 500GB drive be used for the following:

1) Proxmox host, OPNSense (routing), Ubiquiti Controller and possibly PI-Hole (Likely as a container) and to store some ISOs. Is it best to leave everything as default so the LVM-Thin has more of the assigned space or set probox installation to half the storage and set the other half to othere things?

Second SSD used for the following:

1) Act like a main use for 1 or 2 VMs to play around in like Ubuntu or a debian VM host. Never constantly running. Nothing critital 2) use it for Proxbox backups or snapshots (can i do both?) otherwise backups is fine.

I don't have alot of experience in linux on expanding or reducing the size of a volume or if I should even mess with it. Maybe I am overthinking it and I just wanted to try to orgnaize proxmox and storage. One starting with the possibility moving ISO assigned to local and came anew ISO storage on my other drive and setting aside 50-75GB for that.

Also, is best practice should I set up proxmox on one drive first then hook the other drive up afterwards (so don't get the two confused). I assume later I'd have to run commands to create a volume that includes 100% of the space on that drive.

So I guess what I'm saying is:

On second SSD, I want to set up ext4 50 - 75GB GB for ISO, Snapshots and/or backups of CT and VMs, proxmox host and OPNSense.

Just because you're not using zfs doesnt mean you need to use the drives separately, or that you need a file system at all- if your intention was to use ext4, lvm thin wouldn't be relevant as you'd be using qcow2 files, not logical volumes

What I would suggest is mdraid raid one with a LVM VG on top. Proxmox can use the VG without a filesystem, and you'd be able to use lvm thin on top of a fault tolerant block provider.

I know i don't want to use ZFS these due to the masstive amount of writes that ZFS can introduce to consumer drives and how they can wear them down quickly.

"quickly" is a very relative term. Based on your described usecase it will easily outlive your need of it. Really, you would be better off using zfs.
