I want to make a WireGuard network with dynamic IP assignment. Clearly there is no easy way to do it with wg-quick. Is this something Tailscale could help me with? Does it do dynamic IP assignment?

Regarding mergerfs, which create policy would be best if I want to achieve the following:
>pool consists of 2 drives, drive1 and drive2
>downloading to tv/show/, all files are created on drive1 until minspace threshold is reached
>after drive1 is full, relevant paths are created on drive2 (tv/show/) and is drive2 is populated with the rest of the data, as if it were overflowing
I'm currently using epmfs with a minspace of 30G under the impression that this would work, however it appears that despite reaching minspace, files are still being created on drive1.
I've considered using the mfs policy, however if possible I'd like to keep related files as close together as possible, for autism sake.
Sorry for being a retarded anon, these create policy descriptions aren't making sense to me

>>102173180
What do you mean dynamic IP assignment? Tailscale gives each of your machines a "LAN" IP that doesn't change regardless of how the machine moves in the physical space, you can configure one machine as exit node to serve things from.

>>102174348
I'm saying that I want to assign those "LAN" IP addresses using DHCP for v4 and SLAAC for v6 instead of using static assignment.

>>102173986
>an irc server for the neighbourhood
That's nice, does it get much use?

>>102174781
tailscale has a default assignment (that's probably randomized), so if you don't care you don't need to think about it, but maybe you can customize it?

Dumb question about CPUs. I have an E5-1620 v4. It's 4 cores, 8 threads. Proxmox is showing I have 8 cores. If a VM uses 5 cores, will it be okay? I don't really get cores vs threads. I only gave my Win10 VM 2 cores since I assumed it would be half of my cores gone already.

Should I have separate hardware for different services I want to run, or should I just run everything on a single server and virtualize it all? (e.g. media server/seedbox on one one pc and game server on another pc). Maybe a separate pc for everything I want to allow friends access to and one for internal services only?

>>102178047
cores = threads in proxmox. That has 8 threads so 8 cores to assign.
you could have a lot more on the v4 platform if you run out anyway.

>>102176939
Is there any reason why you're not just using the fast nvme as a zlog? Could also use the ssd as a l2arc
I didn't know you could split metadata specifically from the pool like that, I'll have to tinker with it

>>102178437
It's how Proxmox presents the "motherboard layout" to the VM. For most workloads it doesn't matter, just go with one socket and then X cores you need on that one socket.

>>102179157
For the split metadata, what I'm trying to indicate is https://openzfs.github.io/openzfs-docs/man/master/7/zpoolconcepts.7.html#Special_Allocation_Class basically following https://forum.level1techs.com/t/zfs-metadata-special-device-z/159954

My understanding is that you net a reasonable speed increase by storing the metadata on a faster medium like an SSD, and the 2x1tb NVMe seemed like the best coordination of the devices I had available available.

I'm not yet sure if I want a zlog or an l2arc, really. The documentation was rather circumspect about potential benefits, so I was leaning against it

>>102179272
For database workloads (or any synchronous workload), a write will land on the zlog before it flushes down to the pool. So a zlog write on that big 36TB array (but with a nvme zlog) is no different than a write to the nvme by itself.
On the read side, a 4TB SSD will be more than enough l2arc that the majority of your reads (when not coming out of ram) are going to feel like ssd reads from the l2arc.

Yea i have like 3 active users

I'm so in over my head trying to set up backups, and it's stressing me out. Like most things, I can solve it with either more time or more money, and right now, I have neither.

Can someone tell me that it'll get better or send me some good luck/energy? Thank you.

Im stuck between a 3500x and 4500 ryzen for my home lab, obviously the 4500 is the better choice but the 3500x is abit cheaper, do you think i could still get away with running VMs on the 3500x despite the thread differences? also how much does the 32mb of L3 cache actually help virtualization?

>>102180662
It doesn't get better. Just accept now that one day all your data will be lost. Backups are just there to push that inevitable further into the future.
I barely back up my stuff. I would say 95% of it is replaceable media, like things I already downloaded off the internet. And my thinking is that if it's in the internet I'm okay with losing it since I just need to track it down again. The last 5% are personal media, things like family photos and videos, data I will never get back again if I lose it.

Just make a tier list on all your data. Rank them from importance.
Tier 0 is irreplaceable stuff. These are things where I cannot afford to lose them; family photos, videos etc.
Tier 1 is also irreplaceable stuff but still able to get them again through some hoops. Things like tax documents or tax slips from the government.
Tier 2 is replaceable media but things I really, really enjoy. Games, music, movies, shows etc. The things I really like. An example would be LotR movies and books and audio books. I love the whole IP so I back that up.
Tier 3 is replaceable stuff again but for things that if I lose them I would get annoyed and have track them down again. Example are niche books or music or movies.
Tier 4 is super replaceable stuff. This is like Tier 3 but if I lose them I can't be assed to track them down again. Example would be normie movies and music. Media so popular it will never disappear from the internet.
Tier 5 is my garbage tier. If it's here it means I plan to delete them anyways. Things I am not interested in anymore.

That's my list. Then depending on your budget start going down the list to back them up. Right now I only have Tier 0 is backed up with 6+ copies, 3 different media (digital, physical and cloud). And all are in different locations. Tier 1 is just physical copies and in an HDD, also different locations. Tier 2 is just in an offline HDD, in a box, in my closet.

I used to run a setup with USB pendrive that had the Luks key in plain text. If the pendrive was connected, it would read the password from there and decrypt. No pendrive, enter luks key manually.

I have a scuffed mdadm raid assembled from drives in external USB bays on my Manjaro machine (the drives and bays were free and I didn't have free SATA ports or physical space for the drives). Anyway, every time the machine goes to sleep and wakes up, the raid becomes inaccessible. System reboot fixes it every time. I've done some basic diagnosing and the raid and the drives seem healthy. Maybe it's a power management issue, or something to do with the USB controller?

64gigs and one boot drive I think.

So with my Supermicro CSE-815 chassis, I want to place a 2.5" SSD in place of one of the DVD drive blanks. My two options are
>2.5" hotswap bay that's meant for the DVD mount
>2.5" tray DVD blank
I don't need it to be a hotswap bay because it's $60-80 and it's just going to have the server OS on it. The 2.5" tray on the other hand doesn't have its own backplane, which would mean I'll connect the SSD to one of the motherboard's SATA connector. What I'm unsure about is how I'd power the SSD. Would I be able to use the 4-pin CD/Floppy power from the SAS backplane or is a molex to SATA (non-molded) cable the way to go?

Bros, I'm building a smol NAS with 3x 12TB drives in a ZFS pool with TrueNAS. I bought two Exos X18 12TB (ST12000NM000J) drives from different vendors for the different batch factor. For the last one, is Toshiba MG 12 TB (MG07ACA12TE) a good match?
I'm confused with the 512e vs 4Kn thing. For Exos, it supports both according to the datasheet but Toshiba's only 512e (for this model). Some forum mentions that 512e means backward compatibility and that it will use 4K sectors for modern devices but I'm not so sure. Can you help me get this sorted?

Split-horizon DNS properly (for LANs / internal networks) with Cloudflare such that DNSSEC validation continues to work properly?

Right now I'm using Negative Trust Anchors (NTAs) in Bind but this is such a ball ache to maintain.

>>102186033
I should add that Bind is essentially acting as a forwarder but it returns internal IP addresses from the LAN.

iPhones and other devices that validate DNSSEC properly really don't like this without the NTAs.

Kind of a retarded question, but I've added my two wireguard interfaces to NetworkManager as connections. NetworkManager for some reason consistently starts the wireguard interface named "wg1" before the one named "wg0". So if I type in ip a, wg1 shows up before wg0, which kinda pisses me off. Any way to fix this?

Greetings.
My colleague had a bad luck setting up a nested ESXi lab recently, but that's not the story.

When we were trying to diagnose the installation, I'd came across the ESXi's requirements page and it'd said
>To support 64-bit virtual machines, support for hardware virtualization (Intel VT-x or AMD RVI) must be enabled on x64 CPUs.
"Whoa! May it mean that VT-x is actually not mandatory for 32-bit VMs?", I thought, and a quickly-googled Reddit thread confirmed my assumption. "Hmm, I have an Intel D945GCLF2 lying around anyway, which is quite descent (relatively to my other embedded-class mobos), and "this is VMWare" can it effectively host a bunch of retro/lightweight VMs like Minix, ELKS, 9front, FreeDOS, etc. on it?"

The question now is: are 32-bit VMs accelerated by software somehow anyway, like it's done in MSVPC and early versions of VBox/Workstation/GSX, or it actually would be a "proprietary QEMU/TCG"? Moreover, ESXi 3.5 is 32-bit itself which means it can utilize V8086, but how probable that it does?

BTW, have found today tha Intel BIOS is even more buggy than it appeared to be when this system was actually actively used. Is it worth trying reflashing the D945GCLF2 with Coreboot at home?

>twoOStwo, as well as VMware Workstation, Virtual PC for Windows and QEMU with the kqemu add-on, take an even more optimized approach and run code directly when this is possible. This is the case for user mode and virtual 8086 mode code on x86.

Hmm, as I read it: "Parallels WS (as a SVISTA and 2OS2 derivative), as well as 32-bit VMWare WS, MSVPC and QEMU/kqemu (and not QEMU/TCG) utilize VTx-less acceleration techniques, and even that very V8086".

IIRC, ESXi, ESX and GSX have been introduced after Workstation... So, looks like it's worth a try.

P.S. An "real" powerful host with AMD-V is also present but since it's "powerful", it has stricter workhours and thus dedicated to "heavy but occasional workloads" like VDI or GNS3, and always-on services are kept on embedded-ish thus "energy-efficient" hardware (except services used only by VDs).

Thank you for laying that out, but I'm struggling with the automation of backups given my setup. I want to backup my Tier 0 data. It is a photoprism container running on an Ubuntu VM on a proxmox host. So I want to setup PBS to get backups, but I think I need to make another server to host it.

I run FreeBSD on mine since the e-waste PC I'm doing this shit on won't even boot a modern Linux distro without panicking. It works surprisingly well but I can say goodbye to virtualization/containers for a bit.

I'll add that I could probably set up jails to kinda isolate my services but it's not like any of this is exposed to the internet. So far I've got it doing the following:
>generally shitty NAS
>navidrome server
>syncthing backups
>dns through dnsmasq, might look into dhcp to automate even more stuff
Don't even know how healthy the hard drive it came with is, I'm probably going to upgrade it all soon.
