The doc and anyone of this forum is advising to use SSDs for PBS but I didn't found a performance doc that can show the differences. I have a cluster of 3 machines (3x 2T SAS HDD) that I want to backup. Would it be enough fast to use a DL380 witjh 6x4T disks in 1+0 zfs raid? What kind of...

I understand that with 3 nodes I will need at least 2 to have the cluster to be OK. Is this correct? Would it be ok for a smal production server to run on 3 nodes with recent versions of ceph? What should I take care? Also my disks are not SSD but HPE HDD midline 2TB 12G SAS 7.2K rpm. What...

are performance impacted a lot if we setup proxmox backup in a vm? I'm thinking to extend the use of the backup server and be able to launch different vms on it. The vm of the backup server would be mounted on a zvol . Thoughts?

i'm reading this paper: https://vincent.bernat.ch/en/blog/2018-l3-routing-hypervisor and I find it interresting to be able to use the hypervisor as a router instead of relying on another router. It makes the automation easier at some point. In some way this looks like the routed model but how...

Any hint would be welcome. I would like to assign a /48 to each promox nodes that will be used then to assign a /64 or more to the VMsor containers on these nodes. Each nodes would advertise its /48 over BGP so I can eventually also have a /48 unicast range assigned to each nodes for load...

I am actually trying to setup a backup server on a DL-380. Im'm wodndering what would be thedisk right layout when having 6x4TB (SATA DD) and 2x460GB SSD Sata Mixed-Use. I'm thinking to setup the 6x4TB as a RAID 1+0 . Should I install the system on them and use the SSD to build a special...

What are the limitation of the backup server when we don't pay the community license for now? Can we mix a paid license node with another? I would like to eventually ahve a backup failover in case of crash of the main backup server.

So I hear many sirens around, and some are saying that using ceph with 3 nodes may not worth it. Either it is too slow or over complicated. Or don’t achieve the goals of having at least 2 nodes working. Is this really the case? Any feedback is welcome :)

I have 3 nodes with 2x1GB and 2x10GB ports , 64B GB or RAM , 2x 2To SAS (12G) disks with used for the ceph storage. I have for now set proxmox using the Full Mesh Network configuration. But I would like to add redudancy to my network. Since I have 2 10G switch I am wondering if it would...

I would like to be able to backup all nodes and restore a backup without having to re-register them to the license server. What should I ensure to backup for it then ? Where are the files located for it and what I have to pay attention when I recreate the node?

I am following the current documentation to setup an hyperconverged network with proxmox. I was previously using a mesh setup, but since I wanted a full redundant network I figured the setup described on this wkik (translated in english) would do the trick...

I have setup a 3 nodes CEPH clusters with 2x2TB SAS disks on each nodes. What should be the size of an SSD drive to cache the WAL? Would 480 GB be enough?

does anyone know if it's possible to mix vlans and bonds ? Say I have the following: iface eno1 inet manual auto eno1.100 iface eno1.100 inet static address 10.100.1.101/24 iface eno1 inet manual auto eno2.100 iface eno2.100 inet static address 10.100.1.101/24...

I was looking at this link : https://wiki.virtit.fr/doku.php/kb:linux:proxmox:hyperconverged-proxmox-2-liens and the author says it could be doable using the new SDN features. Can we do it diretcly using the UI? A Also I am wondering how the IPs setups can be used by other machines to access...

I’m looking for relatively non expensive 10G switch to handle a convergent cluster fully redondant using BGP and vxlan. I had a look on mikrotik switches but they don’t have a stable MLAG yest and doesn’t seem to handle well a data network. Do anyone tested FS switches? What about a cumulus...

I am wondering if using the HPE E208i-a smartraid controller with disks in LBA mode works correctly with ZFS? Or should I use another filesystem?

I have 3 HPE Proliant DL160 Gen 10 shipped with a storage controller HPE SmartArray E208-i SR. This controller allows to mix raid and LBA mode. Each servers come with 2x300 GB SAS and 4x2TB SAS. I would like to instal proxmox on them but wonder what's the best storage configuration for it. I...

I didn't test it yet but how does HA failover work if i want to keep the service live ? Does it reassign the IP address to the new running instance? Or should i still use something like keepalived? If not what does t used to do it?

I would like to setup a fault tolerant system with 2 nodes only in an Active-Passive pattern with the passive node getting all the data replicated to it. According the documentation [1] we can add an external node to maintain the quorum. Can it be used in a pseudo HA system with the data on a...

What would be the best way to manage a thin client with proxmox? I would like to be able to run for example ubuntu desktop installed on one of the machines on my new MBP M1.
