ok, so let's try to estimate the needed resources for your VMs: How much RAM? How much disk space? How many CPU cores? Is "single core performance" important for your applications? ...and... maximum budget? ;)

Yes, www.proxmox.com seems to be down. You can also download the latest Proxmox ISO from here. The VirtIO driver ISO for Windows you can get here - we normally use "stable", not "latest". If you need further assistance in planning and installing PVE, just ask! :) Greets Stephan

Hi, What's the maximum depth the server can have? Greets Stephan

Hey, is your plan to get one physical machine with local storage, or do you want to have some kind of fault tolerance, replication, HA, whatsoever? Many greets Stephan

Hey, in our PVE environment we installed a bunch of Windows Server 2012 R2 so far - nothing special about it. We use the standard Windows Server ISO. For disks and network interfaces we choose paravirtualized VirtIO devices. Therefor you have to give the VirtIO driver ISO to the VM during the...

Update: Proxmox Backup is able to do what we want: You can go to VM -> Hardware -> Hard Disk -> Edit -> Advanced -> No Backup. :) Greets Stephan

or in fewer words: I would love to do weekly backups of the system disks of all VMs (snapshot, LZO compressed, to an NFS share). High level of consistency (as Proxmox backup does via qemu guest agent) would be fine, but I can live without it, too. Can vzdump do this? Can cv4pve-barc do this (and...

Hi there, we just started with our three node PVE/Ceph cluster - so far so good. Now I'm looking for the best way for "disaster recovery style" backups of our Windows and Linux VMs. At the moment we do backups like this: For file based backups we use Bareos which works well. For (weekly)...

I think I get it: At the Broadcom website you can download the archive SAS3IRCU_P16 - seems to be the current command line tool. Inside this archive you can find SAS3IRCU_P16/sas3ircu_rel/sas3ircu/sas3ircu_linux_x64_rel/sas3ircu Make it executable and start it listing all available controllers...

Hi there, we have seven SSDs behind the HBA mentioned above. How can I find out the mapping between a physical slot and the disk inside Proxmox VE/Debian Buster? A long time ago I used storcli, but I can't find it anymore. Is this tool deprecated? Do you know other tools to handle this? Thanks...

Fine, thanks! I will try this as soon as possible and report again! Greets Stephan

Hey Chris, thanks for your quick reply! Indeed the proxmox management interface is in the same subnet as the backup server. What do you suggest as an easy way to change the backup path? Configuring a second IP address at the backup server's interface so it's also part of a "10 GBit subnet"...

Hi there, is there a way to put the proxmox backup on a seperate network (interface)? At the moment it seems that it's going through the same network as the management GUi - and in our case this is just 1GBit/s, while there are 10 GBit/s possibilities waiting for work. :) Thanks and greets Stephan

I think I found it: ceph-volume lvm zap /dev/sdX --destroy Can you confirm that this is a clean way to start from zero? Thanks and greets Stephan

Hi there, I did a reinstall of my three node PVE/Ceph cluster, and now I would like to clean up the OSDs so that I can use them again as... OSDs :D. Lately I found a nice command for this task, but I can't find it anymore. Can you help? Thanks and greets Stephan

Here we go: 3 Nodes, 7x Samsung 1,92 TB SM883 OSD per node and a mesh network for ceph traffic (Intel X520 10 GBit, 100-150 meters fibre between the nodes): # rados bench -p ceph-pool0 60 write -b 4M -t 16 --no-cleanup Total time run: 60.0513 Total writes made: 17375 Write size...

:) We can't add more nodes for licencing reasons (say "hello" to Oracle and Microsoft), so the three nodes must be scalable relating to storage and RAM.

We have two system discs (RAIDZ1) and we start with seven 1,92 TB SSD per node for Ceph. Maximum per node is 24. ...and because the Thomas Krenn webconfigurator just offers me 8i. :) For a single 1,92 TB SSD I posted a benchmark result here...

Hi again, things becoming true - feels like christmas! :) We bought the server hardware like the list above, with one exception: Instead of the X710 network cards we bought X520. So the servers are mounted into our datacenters, network integration looks good, and I just installed three PVE, not...

Hi, I just ran the first fio command mentioned in the benchmark pdf document on a new Samsung SM883 1,92 TB (MZ7KH1T9). The output goes like this: fio: (groupid=0, jobs=1): err= 0: pid=44035: Mon Oct 7 15:40:04 2019 write: IOPS=26.4k, BW=103MiB/s (108MB/s)(6180MiB/60001msec); 0 zone resets...
