Any solution is use case dependent, which is why this is left for you (the operator) to define, and you can find multiple documents making what seem to be antagonistic recommendations. more pgs/OSD mean more granularity, meaning better seek latency at the cost of more system ram and cpu load...

You're concerned with optimal PG count when your cluster is lopsided. you have two nodes with HDDs, two nodes with a lot of SSD and 2 nodes with too little. any HDD device class rule would not be able to have a replication:3 rule, and an SSD device class rule would end up not being able to...

attach your boot disk to ide when installing. you can change it afterwards.

without seeing the original config file, the only advice I can offer is to remove existing xe-guest-utilities and install qemu-guest-agent before the conversion, and making sure any uefi/secure boot are matched at the destination.

Its worth revisiting what ceph is and how it works. ceph is software defined storage, which is to say there is an algorithm and rules. In a normal virtualization workload the pool rules look like this: replicated size 3 shards (members) in a pg (placement group), minimum required for operation...

If you have a storage product that integrates with Linux in a way that cannot be addressed by PVE, I'd suggest you contact the devs through the normal channels :) But in general, if you can use LVM and ZFS with it, it IS a normal block device. PVE would require the same from any other type of...

Terminal services just requires a TS license. vgpu requires supported nvidia hardware and license- its worth nothing that the latter option is quite a bit more expensive. edit the latter option also requires sufficient enterprise or edu windows 11 licenses as well, whereas the TS option just...

Not with only three nodes. There is nowhere for redistribution to be deployed to. This would be a problem with all three nodes as well. Each OSD is monitored for high water mark. OSDs that reach the high water mark will become read only. By the time this happens the pool high water mark would...

While I cant speak to PVE planning, I can tell you spdk is not meant to replace anything pve provides. PVE depends on linux provided apis for storage and networking; If spdk was deployed to provide said APIs PVE would be able to use them without any changes. If you see an SPDK implementation...

makes sense, and is a good solution for your workload. zfs edges out raid due to features like integrated shadow copies, and performance differences should be negligible. Likely not. Your use case is large assets (photographs of size.) ARC works best with small files- so unless you have very...

JBODs would not have a patrol read option. But more to the point; what is the use case for this storage? raidz2 on HDDs would have TERRIBLE performance for virtualization workloads. edit- slogs dont do what you think they do...

There's no such thing as a h720p. 14g dells used h730 (SAS3.) and yes, these are excellent and the only thing I ever needed to replace on them was the bbu. BUT bear in mind I never ran these past around 6 years old. they can probably last 12, but I wouldn't trust them afterwards- but then I...

I hope you understand that h710p are over 20 years old technology. I dont know what h720p is (if you mean 730 that's better, but still quite old.) If you are relying on an h710 in 2025 your idea of "production" is seriously in need of re-evaluation- they haven't had firmware updates in over 10...

Since you are in control of the code on the remote devices, it may be worthwhile to predeploy a zerotrust type client (eg, cloudflared) with the proper certificate directly onto your end devices. it will add a little bit of cost BUT the security it allows with effectively zero end user...

I forgot about this thread and that your question (and almost everything else I just said) was covered earlier in the thread :) THIS.

The term, risk, doesnt mean what you think it means. there's a RISK of a meteor falling on you. the fact it didnt happen doesnt lower that risk. Same goes for the term absolutely. see Dunning-Krueger effect. The difference between a RAID controller and a filesystem integrated RAID (eg, ZFS) is...

bifurcation is function of the board's northrbridge, which would be controllable vie its bios user interface. first place to check is the user manual, and then onto Supermicro's tech support.

I think you have a completely... optimistic outlook on what you are expecting from this solution. You can ACHIEVE the functionality you desire, but no one is going to make it for you. For starters, Areca controllers have built in features including alert remote, but you have to provide the...

easiest way- use vzdump to backup and restore.

If it doesnt work in terminal mode, your computer/monitor have problems beyond the scope of pve. console remains in text mode and doesnt switch.
