thats ProxMox.If only XCP-NG would give you native management on the nodes, instead of having to run a Xen Orchestra VM just for management
It does. Its called XO Lite and you have native management of the node itself, currently start/stop console, some statistics, but still missing some other features, but it is being developed to be available soon with full feature set.If only XCP-NG would give you native management on the nodes, instead of having to run a Xen Orchestra VM just for management
I think we discussed that a little in hardwareluxx forum some months ago. My understanding (and I am not an expert neither with proxmox nor with EXSi) is that you won't get snapshots that are perfectly consistent with the state of the guest OS by simply doing a ZFS snapshot of the running guest. You would either need to shutdown the OS or also copy the guest memory. Proxomox currently only supports that for snapshots (which are not integrated with PBS) but not for backups made in snapshot mode. So I think you can do safe snapshots with proxmox but it's somehow not what you want to backup your guests :/Consistent ZFS snaps (like ESXi quiesce snaps)
mine regularly runs 400 days before i do any maintenance on it whatsoever. i JUST on Febuary 10th went from ProxMox 6.4 to 7.4. and upgraded RAM, moved to LSI 9400 series cards passed through to TrueNAS CORE.Seems like a house of cards, thrown together with a hope that it will work.
on the RAM USAGE:- Tuning (nic, memory assignment)
You can work around that by making the guests diskless. PXE and NFS. The NFS server is "plain" on the snapshots and would properly snap as if there wasn't a VM.I think we discussed that a little in hardwareluxx forum some months ago.

This is just making it worse with another layer that is not perfectly synced. Snapshotting is not the problem. Guaranteeing that the data in the snapshot is perfectly consistent is a problem and you can not solve that by changing the backend. ZFS supports perfect synchronized writes. The FS won't be corrupt in itself. It's the software that might have data in flight because it is not programmed for situations that are somehow like pulling the plug without knowing when.You can work around that by making the guests diskless.
