Another proof about @LnxBil arguments is that you cannot use LXC container's disk on ZFS over iSCSI storage because on LXC there is no QEMU. Maybe we are mixing terms and referring to different kinds of storage from PVE perspective even if they use the same technologies like ZFS and iSCSI?

Yes, full default settings. Install package, do the restore from webUI. This is the full log, which shows it used 4 restore threads, 16 parallel chunks: new volume ID is 'Ceph_VMs:vm-5002-disk-0' restore proxmox backup image: [REDACTED] connecting to repository '[REDACTED]' using up to 4...

Did a test right now with production level hardware (Epyc Gen4, many cores, much ram, 5 node cluster + Ceph 3/2 pool on NVMe drives, 25G networks and PBS with a 8 HDD raid10 + special device 74% full, nearly 15000 snapshots): libproxmox-backup-qemu0 v1.5.1 progress 100% (read 80530636800 bytes...

It's much more than that. A PLP drive will return ACK to the OS/app once that is written in the cache because PLP will allow that data to be written to the chips no mater what happens (OS panic, app crashes, power loss, hardware failure, etc). Of course, assuming that firmware isn't buggy. That...

Personally, I never ever run any script from anywhere. Not even from known sources like ttek / community scripts[1]. Never really had the need for it, neither in my homelabs nor in any of the clusters I manage. No idea what are you referring to. You apply them in which ever order you want and...

Mate, it's super simple: use the API to interact with PVE and make your tool to do whatever you need. A script, a GUI, a docker, a full blown app... and let everyone to be happy. There are lots of examples with this approach. IMHO: no one wants PVE to become "the wordpress of hypervisors"...

Beware of this if both DC see the remote MON but MONs at each "local" DC can't reach each other. Have you tried that in a lab? It won't work unless you do a lot of manual disaster recovery. No side will have Ceph quorum due to MON election loop. Can't remember the dirty details atm, but AFAIR...

The screenshot lacks the important part of the error, but i suppose that is an INACCESSIBLE_BOOT_DEVICE [1] You must apply "mergeide"[2] before doing the p2v conversion. If you don't it won't boot properly even if it has proper drivers, which is the case if you connect the disks in the VM to...

Use text based UI during install + nomodeset [1] [1] https://pve.proxmox.com/wiki/Installation#nomodeset_kernel_param

Missing a lot of detail here and I may be wrong, but would like to avoid confusion for future readers: that config is not a Ceph Stretched Cluster [1]. That config is a "simple" crush rule that uses a datacenter entity as the primary fault domain, then host. Ceph Stretched cluster mode is a...

True, USB4 is much similar to Thunderbolt and does support networking. Previous USB standards don't have such support, AFAIK.

It slows down the first write I/O of a non-backed-up-yet block because it has to read that block and store it in the backup. If the block has been backed up already or that write isn't the first of the block, it isn't slowed down. The proper strategy for this is to create backup first to a...

Thanks for detailed report. Will try to setup a test environment and try to reproduce the issue following your steps, as I'm curious about this issue and may hit me eventually. Will take me a few days, though... IIUC, PVE has a 1500 MTU on the nic used to reach PBS? QEMU backups create a QEMU...

But for that OP would need some kind of nic that can be used for such fabric, something USB doesn't provide. Or am I missing something? Still haven't played with PVE9.

I agree with @lucius_the regarding the "knobs", as it would allow getting the most of any hardware configuration. We all know both PVE and PBS are run in a very broad spectrum of hardware. At the very least something that can be set on datacenter.cfg, even if it's just CLI. To me having to edit...

Dreaming is free :) Unfortunately USB isn't thunderbolt and AFAIK USB does not implement native networking support that may show up to PVE as a network interface that you could use i.e. to create a mesh network like the one you show. I remember there are/were some cables that have some chip that...

I'm missing important details here, like the storage used in these nodes and some VMs configuration. When backing up a VM, a snapshot is created at QEMU level. When the VM wants to write data over a block that has not been backed up yet, that write is halted, the about-to-be-replaced block(s)...

In fact I gave you a lot of knowledge and experience regarding Ceph and describing much more than a one node failure but the general rules so you can estimate N failures and dimension the cluster appropiately. Never said such thing and dunno what made you think it works that way. Backups have...

Make sure you are mirroring both Debian and Proxmox repos, including Ceph one(s) if you plan to use it. Once mirror is done, you have to use the mirror [1] from PVE. I find it easier to install Nginx on the POM host and add the appropiate apt entries in a .list file (sorry, don't have any at...
