There are a couple servers available at Hetzner (Finland region). You can also order additional hard drives and switches is needed, so you can build a cluster.

Any support for ARM64 CPUs?

We have that smaller server from Hetzner as well. Right now Ubuntu is there, but there is a request from our dev.team to have a dozen of VMs so I would like to build a cluster and attach our CEPH storage.

Not yet, but we are seeking for virtualization solution

You can also change limits on already running process as well: #!/usr/bin/env bash for PID in $(ps aux | grep /usr/bin/kvm | grep -v grep | awk '{ print $2 }'); do SOFT_LIMIT="1048576" HARD_LIMIT="2097152" echo "Changing the limits for PID ${PID}" prlimit...

Please try my solution (steps 3...6) from this reply. You can check the limits with this script: #!/usr/bin/env bash for PID in $(ps aux | grep /usr/bin/kvm | grep -v grep | awk '{ print $2 }'); do SOFT_LIMIT=$(cat /proc/${PID}/limits 2>/dev/null | grep "Max open files" | awk '{ print $4 }')...

The workaround is the next: 1. **/etc/sysctl.d/90-rs-proxmox.conf**: ``` # Default: 1048576 fs.nr_open = 2097152 # Default: 8388608 fs.inotify.max_queued_events = 8388608 # Default: 65536 fs.inotify.max_user_instances = 1048576 # Default: 4194304...

I have the same issue when I have DB server with 10 virtio drives per VM.

BTW, there is an official manual about this topic

@kifeo just found a draft for myself which I had created some time ago: # Migration running cluster to the new IPs ## Ceph Network overview Ceph Network overview was done [in this article][Ceph Network Configuration Reference]. Please read it before you continue with the current page...

It was something from that big list.

reply to my own question: yes

I wonder if you did any set up for OSDs as well?

I have the similar setup: IBM storage device promotes the disks over 2 HBA adapters and I'm using multipath in order to access them. During Proxmox 3.x we had clustered LVM as a storage. Seems like with Proxmox 4.x clustered LVM is not available, because clvmd cannot be started (cannot work with...
