Hi Community, I tried to recover (testing setup only) from a single ceph node, after loosing 2 nodes of a 3-node-ceph cluster (completly, nodes wont ever come back again) I managed to fix PVE-Corosync-Quorum but cant get ceph running again, as I cant do any commands or actions via commandline...

https://www.thomas-krenn.com/en/wiki/ZFS_Pool_Import_-_Proxmox_single_host_reinstall_without_full_backup This should help you doing a reinstall without loosing the already existing zfs pool.

I also noticed that if you do a fresh install, you cant find the repository in the web-ui. It this supposed to be so? root@pve1:~# pveceph install --repository no-subscription --version quincy reef

This one failed for me ( command from: https://pve.proxmox.com/wiki/Ceph_Reef_to_Squid) root@training2:~# ceph telemetry on Error EPERM: Telemetry data is licensed under the Community Data License Agreement - Sharing - Version 1.0 (https://cdla.io/sharing-1-0/). To enable, add '--license...

We updated one of our clusters already, no issues so far (no downtime, everything correct).

On backup creation, when using snapshot mode, the docs say: does this also apply when doing a normal snapshot of a vm or only on backup? So are guest-fsfreeze-freeze and guest-fsfreeze-thaw also triggerd on regular snapshot creation (via web-ui)?

So on Pause Memory is not written to disk, so if the host fails, the paused vm would loose its memory?

Cant find any details in the documentation, can someone tell the difference between pause and hibernate and when to use those options?

The blacklisting should be enough atm, if you cant upgraden. Seems like you have OEM-Firmware not regular Broadcom NIC?

Thanks Aaron! Make sense now! So move-disk to lvm-thin would make them thin-provisioned?

The pool is already in use, so I cant create another one while having the current one still active. Or is there a way to actually do this on cli without loosing the thick pool? Creating lvmthin via webui doesnt give me any options.

Hello Proxmox-Forum :) maybe someone has already tested this out: a customer has made the following setup: * LVM (THICK) Pool 16 TB * Windows VM (VM100) with 3-4 disks ** Disk 1: 2TB ** Disk 2: 500 GB ** Disk 3: 4TB Is there a way to convert a lvm thick to lvm-thin pool? Is there any way to...

So detaching scsi disk and re-adding it as sata, but still havivng virtio-scsi as controller?

Sorry for interrupting. Has someone a summary about the current state: * Whats the error that happens (in short) * What might be the root-cause for the error? * List of workarounds until theres a fix? Thank you for the help. We already tried downgrading driver + io_uring = Native. Is this...

Ich verstehe die Frage glaube ich nicht. Die Datei liegt unter /etc7pve/qemu-server/202.conf und die muss man editieren. Die Anleitung hat auch keinen Step 7

Afaik my guide only works for external not onboard nics. NT = 10GBit onBoard so you need to reach out to supermicro to get the correct firmware. As we do not have N12 in our portfolio I cant help you with getting and testing firmware via Thomas Krenn.

I got a demo a few months ago, did you try the final release? Had some big flaws and things that were missing a few months ago. Will check my notes tomorrow to see what flaws I noticed the last time.

It does work now! Thanks for your help, should I delete the old entries in the .db-file? There is content in it, which is not represented in the web-ui
