    CEPH - one pool crashing can bring down other pools and derail whole cluster.

    Hi, Since we've been migrating more and more stuff to ceph under proxmox, we've found a quirky behavior and I've built a test case for that on my test cluster. Create a small cluster with minimum 4 nodes. create one ceph pool sharing using one disk per node with 4 times mirroring, with minimum...

    Advice for best performing FS for micro vm's on top of CEPH RDB.

    Hi, It's a simple question, if setting up an ubuntu 24.04 server or latest debian - which filesystem is the best to be used for a light weight (memory and cpu), resizable, fault tolerant fs to be used specifically on top of ceph ?! etx4 has it's issues, btrfs did implode on me during vm...

    [TUTORIAL] Re-enroll UEFI keys.

    Hi, one of machines decided go kick it's mortal coil. Machine got replaced, but old disks have been moved to the new machine. Now, UEFI is stating that it can't boot it becuase it doesn't have a right signature. Is there any how-to etc on how to install debian / shim keys into the bios, so...

    are CT cores pinned during runtime or can switch between E and P cores ?

    Hi, I was researching intel P&E arch issues & config with proxmox, and there was a statement (at least for PVE7) that on startup, container cores are allocated and can't be switched over during operation if for example higher load is required. here at 6:43 So my questions are: 1. is that true...

    please update 7 to 8 upgrade doc with default target update.

    To admin: if I'm wrong here, please delete this thread. Hi just a slight request, can somebody add in 7to8 documentation: https://pve.proxmox.com/wiki/Upgrade_from_7_to_8 that after upgrade the default target may need changing back to multiuser ? All of my nodes on upgrade changed to graphical...

    Feature suggestions for PBS backup speedup.

    Hi, After some testing and feedback from proxmox staff, I would suggest: 1. reenable change of compression level during backup to PBS (now it's locked to ZSTD, but in the past it allowed uncompressed). At this point forcing compressions can make CPU bottleneck and also increase load on the node...

    Allow admin to configure required votes for quorum OR out of quorum behaviour.

    Hi, It would be nice to allow admins of a cluster to define either: - a minimum votes required for a quorum (yes, admins might be aware of pitfalls and are prepared to deal with consequences) OR - define behaviour when quorum is not achieved - current "stop everything and just sit there" is a...

    INFO:ceph-create-keys:ceph-mon is not in quorum: u'synchronizing'

    Hi gentelmen: I'm running a tiny cluster with 4 nodes. On Saturday there was a failure and one node started to behave weird. To make ceph chug away I decided to delete monitor from it and just let everything go with its way. Unfortunately I've deleted monitor from wrong node ... and the I've...

    Proxmox 5 beta -> proxmox 5.0 release issues with keys and ceph.

    Hi. Before somebody calls me silly ... I know that this trick shall not be done on production systems ... but I needed some of the features of 5.0 so I jumped the ship early. Anyway I've got 3 systems with proxmox 5 beta 1 & ceph runing as a small cluster and everything was ok. After some time...

    Kinda feature request for backup.

    Hi, You may treat this it as a kinda feature request :) So I've got most of stuff at my workplace running on proxmox, but I've noticed that backup is somehow lacking. This is not meant as bitching topic - so no flames please. So main problem I've got is disaster recovery, right now backup only...

    [SOLVED] Proxmox 5.0 user start up scripts.

    Hi, this is kinda trivial question, but I found usual scripts that should run at the end of level 6 init process but since proxmox and the rest of the world is mowing towards systemd it's all a bit messy to me and it seems that usual suspects don't get run as last ... Also I would like the run...

    Proxmox 4.4 virtio_scsi regression.

    Hi folks, I was successfully using proxmox 4.3 with hard drives passed to VM's with virtio_scsi (both single & pci) without any issue and with any mix of configuration flags (aio, threads, ect ect). After upgrading to 4.4 all VM's corrupted their file systems on passthrough disks (fun). Right...
