Also, today is yet another day of slowly and expensively helping a company recover both their ProxMox and TrueNAS deployments that were done on ZFS and all was lost and no vendor had any means of recovering anything.
Did they back up their PRoxMox to their TruNAS and they both went under?
Or the ghost story of IT deployments.
ProxMox with main storage on TruNAS... ooooooOOOOOOo scary!

Quick update: I did this https://help.nodespace.com/knowledgebase.php?article=307 to all 4 drives, then created a 7.0 TB lvm-thin. Is that the right way to go about this? Here's console output:

That looks correct to me. Convincing ProxMox to use it as an lvm-thin pool might be a bit tricky as it wants a blank block device in the gui....
ProxMox's aversion to the best RAID system available is mind blowing to me. They've completely bought into the cult of ZFS and the Windows world of "software RAID is bad".
@AdamF said in COLO Switching & Power:
For those of you that have workloads in a COLO facility, what are you all using for network switching? Ideally, I'd like to upgrade a network switch I have to a new switch with dual power supplies. (1 power supply goes to PDU 1 in the rack and the other goes to PDU2 in the rack) Any product recommendations for a 24 or 48 port managed switch with dual power supplies?
What products/solutions are you using for single corded equipment for power redundancy? An automatic transfer switch of some sort?
My current workplace uses Juniper EX series switches, they've been rock solid. Previous jobs have used lots of HP switches. I'd probably stick with the Juniper EX series of switches for a COLO as they have many fewer failures.
HP always does a good job with the replacements under warranty, but you don't want to be dealing with that with COLO equipment!
Not all of them are going to have the dual power supplies, so double check the specific model. Juniper sells a lot of new switches that have the option for a 2nd power supply, but only include a single PSU. See: https://www.cdw.com/product/juniper-networks-ex-series-ex4300-48p-switch-48-ports-managed-rack/3122418
@scottalanmiller said in ZFS Pool Online but Cannot Import:
One big thing we've learned about ZFS risks is that it forces a situation where we are dealing with enormous pools of block data in order to do anything and the ability to copy, image, move, backup and so forth is heavily curtailed by the fact that we are forced to work at the array level before ZFS merges the RAID, LVM and filesystem layers together into a single monolith that, if it fails, leaves you so dramatically exposed.
Yep. Just because LVM and MD are separate things, that's not necessarily a bad thing. Especially if you've got devices that can change where they are in the /dev system.
I just realized Proxmox supports Solaris VMs, so I'm doing this today. Talk about nostalgia!
@gjacobse said in Proxmox and USB support:
Not looked at ProxMox enough to remember or know this answer. And before I dive to deep into this personal project.
Can each VM attach to a specific USB device for use?
Specifics, a raspberry 3D printer replacement
I've only verified this with a USB thumb drive, but it's quite easy if you haven't found it yet.
In VM -> Hardware -> Add -> USB Device
I haven't had to run an upgrade on Proxmox myself yet, so I'm just looking at the documentation here: https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0
What is the output of pve6to7 --full?
@CCWTech Are you trying to install on top of Debian instead of installing Proxmox directly?

Finally figuring out how to get my Amcrest video doorbells actually working with Shinobi.
Nice!
How does Shinobi compare with ZM? I haven't had a chance to test out Shinobi yet. ZM works good enough for my home stuff.
I've never really used either before.
My attempt at figuring out the Amcrest doorbell use with Shinobi hasn't panned out so well. Frustrating when I can view the feed in VLC easily.
It took me a minute to get my ancient camera hooked up to ZM, but once I figured it out, it's worked great.
So after working with both Shinobi and ZoneMinder for a couple of days, Shinobi was the clear winner for me.
I never got the previews working in ZoneMinder for some reason. Probably not going to pursue ZM any further since Shinobi is now working how I want it to.

We did that the other day, too. Worked fine for us.
Oh, it did end up working perfectly (as expected). Just took a long time on the little single core linode instance mine is running on.

@scottalanmiller said in Small office replacement network:
@AdamF What hasn't made you happy with Unifi? That's what I'd be deploying.
The APs are still good.
However, Unifi routers aren't that great, and their network switches are more expensive than the competition. Edgerouters seem to have been silently discontinued. I really like the Edgerouters, but am not confident they'll be getting needed updates going forward. I'm at a point where I'd just pick a router without integrated wifi and call it good.
For a network switch, I'd consider looking at used gear. For work, we use old Juniper gear all the time, they're rock solid all the way back to EX2200 models. If you care about warranty, you could pickup a used HPE.
There is something to be said for ease of usability/management. I think Ubiquiti makes some products that would do almost everything you need in 2 products that you would manage together. The time savings could well be worth it for a small one-off place like this.
@popester said in Ubiquity U-LTE:
My brand new U-LTE cellular failover device from Ubiquity appears to have lost its APN setting. I guess default is not the Dallas Fort Worth metro plex in texas. It is the one that AT&T has its hooks into, or at least from what i understand. Has this happened to someone else? I can get into the config but do not want to touch any settings for fear of doing more harm than good. I reached out to Ubiquity Support and they shot back that I needed to get the correct settings for the device from AT&T. Not real sure how to do that. Have found lots of information. Since i am paying ubiquity a monthly charge for the service I am not sure who to reach out to. Anyway. Any help would be appreciated.
Have you had any contact with AT&T, or was it all Ubiquity?
I deal with cellular data things as the majority of my work now, so I may be able to help.
This process was simpler than the official instructions make it. I'm using the unlicensed repository.
https://pve.proxmox.com/wiki/Upgrade_from_7_to_8
When you get to the section about updating repositories, only the first update is necessary.

@openit said in If starting from scratch, would you suggest learning BASH or Ansible?:
Hi there,
While I'm preparing for RedHat certification, I was thinking to learn BASH, for general use and also exam has requirement to write simple bash scripts.
But, in long run and to be more efficient, I feel deep learning of Ansible is better than BASH? If I left BASH, and go with Ansible do I lose anything? I assume Ansible covers what BASH can do?
Appreciate your suggestions.
I don't think that's an either/or question, it's which one should I learn first. Ansible is so good because it doesn't try to do everything for you, it does a lot for sure, but not everything. Knowing both BASH and Ansible lets you automate anything you could possibly want to do.
If starting from scratch, I'd say to learn the basics of BASH. Then really dig into Ansible. I think you'll find that if you use Ansible to it's full potential, you'll also have to learn to use the shell (BASH is only one.)
