Kann ich verstehen. Am besten dokumentiert ihr das aber, um nicht in Zukunft verwirrt zu sein, falls die normale replicated_rule sich nicht ganz so verhaltet wie man es glauben würde ;)

They can be on the same physical network and even the same IP subnet as well. It is no hard requirement to separate them. It is a possibility to spread the load. Ideally, Ceph will be the only service using the physical network. Otherwise, you can easily run into the situation that multiple...

Neues Root ist nicht nötig AFAICT. Du willst ja nur je einen Pool auf den SATA und einen Pool auf die SAS SSDs legen oder? Device class specific rules reichen voll aus. https://docs.ceph.com/en/latest/rados/operations/crush-map/#device-classes Device classes können frei vergeben werden. D.h...

To what storage type are you moving the disks to? Because dd'ing zeros to it is usually not a good benchmark. On ZFS that would result in almost no data written to the disks at all. What kind of disks are in use? Are they consumer SSDs or datacenter ones with PLP? Are there other tasks /...

You can have your own custom storage plugins. Documentation is currently a bit lacking (something we will hopefully improve soon). But taking a look at the code of existing storage plugins can get you started.

to remove nodes from a cluster, follow the admin guide https://pve.proxmox.com/pve-docs/chapter-pvecm.html#_remove_a_cluster_node if there are no guests on that node, then yes.

try hitting any key when the console has the focus. The login prompt should show up after that.

well, those are just the config files. It is possible that it works because their disk images were not stored on the disk on which you installed Proxmox VE to. Probably the ZFS pool or the network share? Otherwise, the procedure would have been to mount the filesystem of the disk on which you...

What is the storage config from the backup? (/etc/pve/storage.cfg) That would be a first guide on how the disk on which the backups are stored is configured. Depending on this, we would know how to make it available again so that the guest backups can be restored.

I haven't tried it myself yet, but there is this script that promises to generate a pxe boot image from a Proxmox VE ISO: https://github.com/morph027/pve-iso-2-pxe The boot options will most likely need to be adapted as you need to pass proxmox-start-auto-installer as kernel cmdline option.

Why do you store VM disks in a Ceph FS and not an RBD pool? Besides that, I guess you ask why the source is san-vm:vm-202-disk-2 and the target vm-202-disk-1.qcow2? The storage plugins will usually just use the next free numerical ID at the end for that storage. Therefore, the order in which...

That won't be possible. If the node on which the HA VM is running is losing the connection to the rest of the cluster for longer than 1 minute, then it will fence (hard reset, similar to pushing the reset button) to make sure it is powered off, before the (hopefully) remaining rest of the...

I am a bit confused. The large clusters should be fine regarding quorum, up until 6 nodes are failed. The only cluster that really needs an external QDevice is cluster 3 to get up to 3 votes, and therefore maintaining a majority if one of the two nodes is down. And the external part of the...

I finally got around to test the different scenarios. The manual graphical installation was done with these disk settings: hdsize: 120 swapsize: 8 maxroot: 30 minfree: 20 maxvz: [blank] Then the first answer file, with only the necessary disk settings for LVM: [disk-setup] filesystem = "ext4"...
