OpenZFS data loss bug: https://www.theregister.com/2023/11/27/openzfs_2_2_0_data_corruption/

No surprise to anyone paying attention, and not a part of "The Cult of ZFS"

Ordering yet another printer… and I think I have three more that will be needed in the near future…. Crimmy

Is it the worst of the worst and label printers?

Yup,.. I have a fleet of ZD621 printers and another large model with rewind…

Here, I have the solution for you...

I've been so busy on so many calls, what kind of issues?

Look at your Telgram feed, it's already been posted there.

We have a customer that would like 24/7 helpdesk support. We are not able to provide this. Are there companies how offer helpdesk services as a reseller service?

NTG... @scottalanmiller You'd be the source for this, but sounds like it's something NTG would do.

Moving from iOS to Android...
Honestly wasn't ready to but events have transpired to move things along.

Not sure how I feel about it.

I liked it when I did it. And then regretted it when the instability and hardware problems came, and the lack of vendor protection. It's weird the things you don't think about in iOS are often the killer features. From an interface and usability standpoint, I liked the Android better.

The whole vendor support thing really irks me, as some vendors support for their phones varies by model.
Luckily(?) I'm got the use of a Pixel phone and updates are good (just got Android 14 today!).

Even Pixel update support sucks monkey ****. They're great at getting updates out for supported devices, but devices are only supported for 3 years from the first day the device was sold in retail. For those of us that don't update phones regularly, that still blows. Apple has Google beat hands down in this area.

I say this while my personal phone is still a Pixel 3a XL. It works fine, but I've been growing more concerned over lack of updates for a while now. While I know I should upgrade, it's working great still.

Root it and install a custom rom? I've done that when I've managed to keep a phone beyond it's usual updates.

I've been looking, but haven't decided on a rom yet.

i've always had android, since smartphones began. just can't make myself get an iphone. now i no longer care, purchasing is based on cost. recently had to get, didn't want to, had to get, a new phone. hard to go past a samsung with more features in it than an iphone for only $AU350.00.

not saying android is better than iOS, I don't care, but I am saying that spending $350 is way better than over $1000.

I go for what is cheapest per year of having a phone.

If you can get a deal on a latest Samsung Android phone, it can be like $120-ish - $200 per year for 4 years (I got a new Samsung S23 for less than $500 locking myself in with TMobile for 2 years after I traded in my old one). I say 4 years because that's how long they (Samsung) typically support phones, providing security updates and such. Being what phones are today, it's a requirement to always use a phone actively receiving security updates.

Sure, you might be able to get an S20-S22 for like $2-300. But then you have to do it again in a year or 2 years or it will go out of support. Thereby increasing the per year cost of having a phone.

I saw, after complaining about it, that Google is going to support phones for 5 years now starting with the Pixel 7. So that's vastly improved, but I don't want to pay for one of those yet. The plan we use doesn't comp phones, so it's way cheaper in the long run.

@scottalanmiller Can it run little proxie server with sim card support?

SIM card? You'd need to find a SIM card hardware for that. It's a computer so it can do whatever you want. But does someone make the hardware to add onto it for that?

Lots of add on boards are available to get cellular connectivity with Pi, Arduino, etc.

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?

no, no backups. Data was all stored on TrueNAS. TrueNAS was stored on ProxMox. "ZFS is so reliable you don't need backups" was the idea, I guess. And no hardware failed. Just ZFS failed. Pure software failure. All hardware is pristine and working great. But ZFS just lost... everything due to internal design fragility that makes it prone to data loss on reboot.

Original IT company seems to have known this and disabled all reboots. Kept them up for 2.5 years. First reboot after going live resulted in total data loss because ZFS on Linux isn't expected to reliably survive reboots in that way!

Dang, and here I thought my ghost story was scarry!

ProxMox with main storage on TruNAS... ooooooOOOOOOo scary!

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.

@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
