gurubert reacted to t.lamprecht's post in the thread [TUTORIAL] QuantaStor Proxmox Storage Plugin with
Like.
Hi, Thanks for sharing your work. Upfront, are you aware of the native plugin mechanism that Proxmox VE offers, or are there reasons for developing this plugin as patch of the code over using the defined plugin interface? See... -
gurubert reacted to cagamps's post in the thread [TUTORIAL] QuantaStor Proxmox Storage Plugin with Like.
Hello all! I'm a developer with OSNEXUS. We’re excited to announce the pre-release version of the QuantaStor Proxmox Storage Plugin, designed to simplify the management of QuantaStor storage within Proxmox VE clusters. This plugin enables...

gurubert reacted to ness1602's post in the thread VMFS equivalent in Proxmox? Shared iSCSI filesystem across multiple nodes with Like.
For stable cluster CEPH is the only way to go.

With PVE on a shared LUN you use LVM to split it up. That is a block storage. See https://pve.proxmox.com/wiki/Multipath that also touches the final setup after multipathing (which you will usually have in such setps). No, that is a complex...

gurubert reacted to spencerh's post in the thread Unattended install of Ceph using pveceph with Like.
I believe that is what I was referencing in my original post: I ended up just going with figuring out what packages are installed by pveceph install and installing those directly using apt.

gurubert replied to the thread Difference between Ceph already integrated into Proxmox and installing Ceph externally.If you need more than RBD (block storage) and CephFS (file storage) from your Ceph cluster you should look into not deploying it with the Proxmox tools.

gurubert reacted to bbgeek17's post in the thread Proxmox 9 with shared LVM on iSCSI problem with Like.
VMware enables this behavior because it has VMFS - a cluster-aware, shared filesystem. VMFS implements proprietary on-disk locking and reservation mechanisms that safely coordinate multi-initiator access to the same disk. Proxmox does not...

gurubert reacted to bbgeek17's post in the thread Proxmox 9 with shared LVM on iSCSI problem with Like.
You cannot have Shared storage in a two node non-cluster installation. Shared storage, as defined by PVE terminology, is part of the cluster. Everything you do after that is a road to data corruption. There are coordinated operations...

gurubert reacted to Lukas Wagner's post in the thread Cross cluster migration should have option to automatically re-VMID to range config on target cluster with Like.
It's something that we are already planning to fix, but I cannot provide an ETA at the moment.

gurubert replied to the thread VMFS equivalent in Proxmox? Shared iSCSI filesystem across multiple nodes.We are running a cluster of 8 Proxmox VE nodes with OCFS2 on a SAN LUN since several years. It works but it is not officially supported. There were some issues even with OCFS2 in recent kernels as the development of OCFS2 seems to have come to a...

Hi @PelikanNetzwerk , welcome to the forum. Generally users have reported success using vanilla Debian to bootstrap on iSCSI and then installing PVE on top of it. https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_13_Trixie There are a...

Hello Nick, I've always hated the NetApp sales in Germany, who present NetApp as the optimal block storage for VMware. I always perceived NetApp as the best filer and the Ontap products probably still are. VMware's strong focus on block storage...

gurubert reacted to t.lamprecht's post in the thread Ceph 20.2 Tentacle Release Available as test preview and Ceph 18.2 Reef soon to be fully EOL with Like.
Hi Community! The recently released Ceph 20.2 Tentacle is now available on the Proxmox Ceph test repository for installation or upgrade. Upgrades from Squid to Tentacle: You can find the upgrade how-to here...

gurubert reacted to bbgeek17's post in the thread [TUTORIAL] Understanding QCOW2 Risks with QEMU cache=none in Proxmox with Like.
Happy New Year! Sorry for the delay on this... we wanted to do a proper analysis. Both cache=direct and cache=writethrough provide substantially stronger consistency guarantees than cache=none. If you are using QCOW/LVM and consistency is a...

Du hast völlig Recht. Ich dachte fälschlicherweise immer clean stecke in apt autoremove drin. Aber clean ist nötig um fette Leichen, eher mikochirurgisch als mittels Holzhammer, endgültig zu beerdigen. Danke.

gurubert replied to the thread [SOLVED] Wie kann es sein, dass.Die Dateien unterhalb von /var/cache mögen zum Teil volatil sein. Die Verzeichnisstruktur ist es sicher nicht. apt clean hätte unfallfrei aufgeräumt.
-
Das scheint mir ziemlich viel zu sein. apt clean kann das bei Bedarf eventuell etwas minimieren.

gurubert replied to the thread Ceph NVMe-oF gateways with PVE.NVMe-oF in Ceph works from version 20 onwards. Do not try it with reef or squid. And AFAIK you need the cephadm orchestrator to configure it.

gurubert replied to the thread Ceph Squid (19.2.3) Cluster Hangs on Node Reboot - 56 NVMe OSDs - PVE 9.1.1.No, as soon as there is no quorum any more between the MONs, i.e. the majority of MONs do not see each other, the cluster will stop working. And for the number of MONs: The cephadm orchestrator deploys 5 by default for the reasons I outlined...

gurubert replied to the thread Ceph Squid (19.2.3) Cluster Hangs on Node Reboot - 56 NVMe OSDs - PVE 9.1.1.The current recommendation from the Ceph project is to run 5 MONs. With only three MONs you run into a high risk situation after losing just one MON. Losing another and your cluster stops. With five MONs you can loose two and the cluster will...
