Nice! Cheers

Much appreciated! Cheers!

Thanks for the info.

Nice!

Hm, food for thought.

Hm I haven't had that happen. I set Proxmox up to back up the TrueNAS VM and it only saves the VM setting nothing from the pools. It may depend on how you are setting your backing up options, but I really haven't explored that much. It just kinda worked for me. Sorry I don't have any suggestion, but to check out the documentation and hope you find something. Cheers

You should let TrueNAS handle the ZFS by passing through preferrably a whole SATA controller. Some people put a dedicated controlelr in just for this, if you are not able to pass through individual disks.

Sam hit the nail on the head.

I ended up just ditching Truenas all together. I don't need it for VM obviously, just file sharing, so it's really overkill for that.

Awesome

I agree. I am actual in the process of moving everything to TrueNAS Scale.

@@LoResDIY my main issue before moving to TrueNas scale is that it seems impossible to virtualize a macOs Machine in trueNas. Have you plans to do it?

from my own limited experiences truenas doesnt like to virtualize when its being virtualized - i have an error message appear when i attempt to create a vm within truenas. however, if you were to somehow get this working, a share is available to any computer that can access the network. As truenes is virtualized and (if you chose virtio when setting network adapter for truenas within proxmox) the network capabilities of truenas is virtualised also, running network tasks is limited on the hardware of the machine. If you were to create a windows machine within truenas and that windows machine had network access it would be the same as any other computer accessing shares - go to explorer and enter \\192.168.0.*\ (the ip address of the machine the share is hosted on, in this case it would be the ip address of your truenas vm which will be different to the now created windows vm inside of truenas) - again, this is from limited expirience, if im wrong i hope someone corrects me.

If you were to create a linux VM in Truenas it would not be able to see the shares that you have created. The VM thinks it's a real computer all on it's own; so if you wanted it to see the Truenas shares you would have to tell it where they are located at. You would also need to make sure you have the permissions correct for the share and the VM. I'm throwing around the idea of creating a TrueNAS bare metal server and doing a serious of videos that would cover ZFS pools, shares, permissions, snapshots, etc. Do you think this would be of assistance?

Thank you! Cheers!

No it doesn't sound like a hardware problem. I'm wondering if you are maxing out your network and it appears that Proxmox is is slowing up. Otherwise I'm not sure what would be causing that to happen.

@@LoResDIY I am not sure about maxing the network? i am on 1 Gb network but i have all my VM's on one dedicated Lan Port and Proxmox is on another port and TrueNAS VM itself has it is own Port. but why you think it is network since all the setup is on one server and data moves with in the same server. will the data go from the trueNAS to the VM's through Network switch which is 1Gb and you think it is reaching a bottle neck ?

Oh I was thinking you were going from a desktop to the server not VM to VM. I'm going to spin up a windows vm and see if I have the same problem.

Thats a terrible idea. Just flash the hba to it mode and pass them through.

If you passthrough an hba yes, but if you passthrough individual hdd/ssd's than no

I am experiencing the same issue, but have yet to find a solution. Sorry no help at this time.

@@LoResDIY well I can say that if you pass it through as SATA to openmediavault it does work ... Guess TrueNAS Core (which is not Debian based) doesn't like it either way ... Maybe TrueNAS Scale can handle it properly

I run truenas scale on proxmox myself. The benefit for me is that I have a multi purpose machine without the need for all the extra hardware because of a bare metal setup. The downsode is that it can be a hassle to passthrough certain hardware, there also is some overhead and accoriding to ixsystems; it might be unstable

@@denniskluytmans Isn't Truenas Scale the same thing as Proxmox except different providers? Like why do you need Proxmox in your system rather than just using Truenas Scale?

@@Tanax13 truenas scale is the same as truenas core but with scale capabilities like high availability, docker, k8s and VM's. The scale base system is still core though, but on Linux based. The main purpose for scale is like for core; NAS

Dang I was a bit slow at getting to my comments, but Dennis hit the nail on the head. Cheers

@@denniskluytmans that wasn't @Tanax question. If you setup samba on Proxmox you'll have something like TrueNAS

😮 so better not to pass through the disk wow I was just to do this as is straight forward and I did not know what you said will review about HBA thanks 🙏

do you have any resources regarding you claim that it does not like direct passthrough?

Those are the recommendations from TrueNAS. I have ran machines with less ram before with no problems.

@@LoResDIY Like 8 gb for 18 tb?

@@AlonsoVPR I would think it would run with 8gb, but it may act oddly and be really slow. TrueNAS uses ram to cache the most used files and hopefully speed their load times up. I would suggest 16gb as a min., but hey give it a try with 8gb and if need be bump up to 16gb.

Yeah I use Epic Pen while I am recording. They have a Basic (free) and a Pro version (pro cost $25); I use the Pro version to have access to the arrow command. epicpen.com/ Cheers

@@LoResDIY thanks

Passing the card through is the best option

@@LoResDIY i see. Thank you.

That's no fun

You don't need that much memory. 8 gb is more than enough, 16 is just plenty for virtually anything you could want truenas to do, with all of the [officially] available apps running at once. You do need a lot of memory FOR DEDUPLICATION, which you don't want to use for general purpose storage. And even if you need dedup for any strange reason, you don't have to enable it for the whole storage, so you still don't need much memory.

Thanks for the info

I tried some different mic settings. Sounds like they didn't work. Thanks for the feedback (pun intended) .
