Thanks for clarifying. So the boot partition is that where GRUB resides and EFI holds the boot-loader on a UEFI system? (I am trying to learn about the partitioning scheme and boot process). Yes true, but I guess it is best to keep them the same size. Not sure how large I should make the...

Thanks for the reply @ph0x. From that i have understood the Proxmox installer will create several partitions on the disks (including root, boot, swap, maybe more?) The hdsize that is defined in the GUI during the install process is that combined space for all of these? I'm comfortable with...

Not sure why I am even allowed to set 476GB when selecting a RAID1 (mirror) configuration. Should the max size not be 223GB? The disks will not be used for SLOG. I will be using 2 x Intel D3-S4610 256 GB SSDs. I am comfortable with the drives failing earlier. I am looking for the how to do...

I am installing Proxmox on two SSDs in a ZFS mirror (RAID1) configuration (why does the hdsize show 476?). Proxmox itself should not take up to much space and my VM/LXC space will be on separate drives. How much space should I make for Proxmox and could I use the rest for an L2ARC stripe...

Hi @Dunuin. Thanks for the reply. I am not using ZFS here. Everything is running on a single drive. I might consider buying some more RAM later, but for now, for this particular server, the load is pretty much constant and within limits. I am just looking at optimizing resource allocation...

I am quite new to Proxmox and I have been trying to read up on the subject of resource allocation, but I still find it difficult to determine the best practises. As an example I have recently set up Proxmox on a small computer with a 4 Core i3 CPU and 8GB RAM. I have configured 3 VMs; pfSense...

Interesting. What is the advantage with SSHFS vs NFS? Also could you not run Plex in an LXC?

Thanks for clarifying. I think NFS is the way to go for me! Yes, I've seen many tutorials, but not being very familiar with either NFS , ZFS or Proxmox I was not certain how they related to Proxmox and the best practises there. Thanks for the link! I will check it out. Do you mean for...

Thanks for the reply @ph0x As you can see from the drawing I am planning to to have multiple VM's which should be able to access the datasets so passing an HBA through to one of them is not an option (in either case all the HDDs are connected to the MB). I have seen several mention of...

Hi experts, I have read a bunch of post on this topic, but have still to find a clear answer to this. My intended setup is as depicted below. I need a proper way to access the ZFS datasets on the HDD storage pool from the VMs. What is the best way to accomplish this?

Absolutely, but I think the context is sometimes forgotten and often the ones that are trying to help lives in different worlds and speaks a different language than the newbies looking for help with different requirements and risk profiles. I make this mistake all the time myself trying to help...

Perhaps you should provide some more details of your setup. Then it will be easier for people to help. For instance how are you using the RAIDZ1 pool? Is it used for the Proxmox host, the VM images as data storage for the VMs? How have you configured you pool(s), what ZFS options have you set?

With regards to enterprise SSD I actually thought it was the opposite when it comes to speed. I.e. that consumer drives are typically faster, but with lower lifetime than enterprise SSDs, but maybe I have misunderstood. Maybe someone can elaborate?

You are not the first! :) Although I must say, since I have no experience with this myself yet, I am getting really confused based on the feedback I am getting. There are equally many people who states that this is not an issue as there are people preaching doomsday scenarios if using consumer...

I have been reading the OpenZFS Performance and Tuning document and came across this section: In practice, how is this done in Proxmox? Lets say I have a a couple of dedicated SSDs for VMs/LXCs configured in a ZFS mirror. How do I create a new VM storing it on a ZVOL and what will be the...

Thank you for the informative answer!

Could someone please explain ZFS TRIM on Proxmox? Particularly the difference between setting autotrim=on and using zpool trim and best practices for use on SSD zpools an a Proxmox server (simple home lab server).

The DBs would then be on the SSDs as part of the VM data, which could get corrupted yes, but probably nothing that could not get rebuilt quite fast I think. As much complexity using ZFS on the VM drive seems to introduce to me it feels like a bigger risk as long as one cannot afford very...

I know, old post, but I am looking to do the same thing and I am not familiar with NFS/SMB and just learning ZFS and Proxmox so I have a couple of noob questions: When you say "bind mount the storage to it" do you mean the whole zpool or just individual datasets that you would want to share...

Yes, I guess so, but since the actual data (files, media and whatnot) used by the VMs/LXCs would be stored on the HDD ZFS pool would it matter if you got a corrupted file on a VM or LXC? In that case it would most likely be a "system" related file which should not be that critical anyway as you...
