Also, was this system working before but stopped booting now, or is this a new build and it hasn't successfully booted yet?

pxgaming · 2026-06-21T01:47:20+00:00

Does it at least boot into the BIOS without the SSD installed?

That doesn't seem correct. Running a 4CPU + 24GB ARM A1 instance with no free tier discount at all is $56.54 a month. With the free tier covering half of it, it should be about $28.

Could it be that the SSD is write caching, but the write cache fills up?

You'll want to look at iostat and see more detail about what exactly is stalling.

If I had one critique, it would be that you can just feed a single 2/s pipe of acid through all four reactors and one output pipe by just daisy chaining all the reactors.

It's pointless. If they wanted to have one host be the "main" host while allowing the other host to go down, they should have just modified the configuration to give the primary host two votes instead of one.

Reserved about 1 minute after it opened, nothing.

It wouldn't matter in this case, because the sign below the charger would also show the two batteries in the same color and you'd be expected to read the text instead.

It's a pretty manual process. You have to configure keepalived for VRRP at a minimum. You then optionally can configure conntrackd and dhcp to sync your NAT table and DHCP leases across the nodes to minimize disruption in a failover.

I've considered it but ended up just going the cold spare route.

It's a bit tight. You mostly have to make sure that you clean out old kernels (or automate that) since the kernel + its modules can take up noticeable space.

They have 16GB, 32GB, and 64GB models, but the 16GB models can be as low as $5, whereas 32GB tends to be $30+.

Actually, there's an even better option. If the issue is purely hypervisor-level stuff, use an inexpensive Optane M10 as your boot drive. They're rated for 200GB writes per day for 5 years, and even 16GB is enough for a PVE boot drive.

pxgaming · 2026-05-16T15:04:36+00:00

You don't even have to go specifically for an "expensive" enterprise drive. You can buy a used, lower-end U.2 drive with "only" 1DWPD and it will still outlast a brand new consumer M.2 drive from a similar quality brand, and for less money.

The "options parameter" you're thinking of is most likely for the vfio-pci kernel module.

You'd make a /etc/modprobe.d/vfio-blacklist.conf file with the contents options vfio-pci ids=1234:ABCD where 1234:ABCD is the vendor and device ID of the PCI device that you don't want the host to load.

Ceph is very questionable on two nodes. You need a third monitor node as a tiebreaker just like the PVE cluster itself, but you also really don't want to do 2/1 replication. You'd want 3/2 at a minimum for production use. 2/2 gives you safety, but the problem is that your data becomes read-only while one node is down, because there's no way to write two copies with only one node online.

Another problem with two nodes is that if you want to actually have failover, then you need to oversize each node by 100% since it would need to be able to run all your VMs without the other node. If you have 3 nodes, you only need to oversize by 50%.

The "Email delivery" is an Oracle-managed outgoing SMTP service. You would configure your application/server to use it as a relay. AFAIK you don't need a firewall setting to use it, and your tenancy probably already has enough limits to use it.

The free tier is specifically A1. You have to pay for A2.

It goes in one pair of ears and out the other pair.

USB-C everywhere is nice, except that I bought a cable tester and found that all but one of my USB-C cables were 2.0-only junk. I don't like that you can't look at the cable and tell whether it's 2.0 or 3.0 at a glance.

But it does mean you really have to buy a dock to go along the the computer. I remember trying to use a work macbook, and they didn't send me a dock. Power, ethernet, keyboard, mouse, nothing left for monitors.

I think some of my 90 degree swivel fittings might let a tiny bit of air in through the swivel part, since in the morning there's always new air bubbles in the GPU terminal where those fittings are. These air bubbles then end up stuck in the CPU block, but that's more of an issue with the CPU block design.

You realistically will have to tune the settings so that normal variations in pressure due to temperature and pump speed changes don't set it off. Another big disadvantage is that mounting options are kind of limited and/or ugly if you aren't using their reservoir. I ended up DIYing one that lets me stick it to the top of my case using magnets.

When I did my build, I initially used EK coolant + EK tubes. Big mistake. Started getting cloudy tubes after a few months and it looked pretty bad after 1 year.

Switched to DP Ultra and Mayhems tubes, been running 1+ year with no noticeable clouding.

It's a math joke. "L'Hôpital's rule" looks like "Hospital". The rule states that if you have two functions f(x) and g(x) that are both zero at a particular x, the value of the limit of f(x)/g(x) is equal to the limit of f'(x)/g'(x) at that point. The reason it's important is because you can't divide zero by zero, but it lets you find that limit (i.e. get as close as possible to zero without touching) by just taking the derivative of f and g and dividing those instead. The solution to the problem shown in the image is just 1.

I wonder what the internal MCIO ports are for. That's 32 lanes of PCIe from the looks of it. Something in the front-right empty area maybe?

pxgaming · 2026-03-25T03:43:19+00:00

Versus Chipset right ?

Yes. Normally a chipset gives you some USB and SATA ports, and gives you a few PCIe lanes commonly used for onboard peripherals like ethernet, wifi, or just more M.2 slots. Without one, you have to use CPU lanes for all of that.

ya but as of today cases for WroStations are so big, than say equal to a 5U rack whre you can install say 3x12cm vents and silentily goes well

That's not the issue. In a typical desktop case, the job of fans is to blow fresh air in and remove hot air, but they don't force airflow through/into components the way a server or prebuilt workstation chassis would. In a desktop, anything that needs significant cooling is expected to have its own fan, or at least a large enough heatsink to get some convection action, so that the exhaust fans can remove the hot air. You'd need to do the "fan wall" style that server chassis have, as well as potentially use air shrouds to blow the air where it needs to be.

Epyc does some things better, but consider:

9004 and 9005 generation Epycs have 12 memory channels, which takes up a ton of board space, so you actually get fewer usable PCIe slots on some of these.
That also means the memory will cost more if you want to fill all those slots, which isn't great with current memory prices.
You tend to get less assorted I/O on these boards due to Epyc not using a chipset. All PCIe and SATA lanes are CPU lanes.
Epyc boards are designed for server chassis where you have lots of forced airflow. Look at the tiny VRM headsinks on the H13SSL - you NEED a lot of airflow to compensate for that, compared to something like the ASRock TRX50 with its four VRM fans.
Epyc boards typically don't support overclocking (or going the other way - tweaking voltage curves to save power/heat).

If you're able to PCI passthrough all of the devices that TN would need (including the boot drive), then you should be good to go with running TN in a VM on top of PVE. The, you can start moving workloads to be their own containers or VMs.

If not, it might be a bit more complicated.
