I guess this will work but you are not satisfied. You would need more memory for ceph and the separate network are strict requirements. This is a ceph benchmark with this Samsung disk.[1] The CPU will stong enough. The problem with this network still exists if you have no second port for the...

Hi, IMHO you have 2 options. 1.) replace the HW raid against an HBA and use ZFS. Then you can use the pvesr[1] to replicate the VM data. Also, a third node is necessary. This node is for the qdevice[2] what keeps the corosync quorum. This node can somewhere. This approach has the drawback that...

Yes, e.g. 1 Gbit failback. Is it possible to add another 10Gbit to the NAS? If you like to go the ceph way, I recommend another two-port Nic with min 10Gbit or better use 25GBit. 25Gbit is not more expensive than 10Gbit. The cost comes with the switch. But for 3 nodes, you need no extra switch...

Hi, Proxmox VE does not support the use as an iSCSI target. What target do you use? LIO is the better one.

Hi, ZFS is not compatible with HW Raids.[1] So please use instead ext4 or xfs [2] with thin-lvm[3]. 1.) https://pve.proxmox.com/wiki/ZFS_on_Linux 2.) https://pve.proxmox.com/wiki/Installation 3.) https://pve.proxmox.com/wiki/Storage:_LVM_Thin

You are correct about RSTP is not supported by the Linux bridge model. May MSTPD[1] is a solution to this problem. But why in a Layer2 network use RSTP instead of a bond with active-backup? Or do you build trees with your nodes? OVS is known to be not perfectly stable. This is the reason why I...

Hi, why do you do not use hibernate on the PVE side?

In this case, your network is a single point of failure, and it isn't easy to compensate for this. The problem that I see in this setup is. When the storage network becomes pressure the switch could easily overload and will not transport the other packages as fast it is necessary. Corosync is...

Can you explain a bit more? Because RSTP makes no sense if you have just one nic on the switch. IGMP and MLD snooping is supported by the Linux bridge model and ifupdown2 add this setting in the bridge section at the interface config bridge_mcsnoop yes to control if it is running you...

Hi, only to prove I understand you correctly. The base network setup is 2 x 1 GBit port 2 x 10 Gbit port but you like to use only the two 10Gbit ports? and these ports are connected to one 10Gbit switch?

Hi, why do you use OVS? Proxmox recommends using the Linux bridge model because it is less complex and more stable.

Hi, please update to the latest version. There are all running tasks at the right top position.

Hi, the problem is that a block in the dirty bit map can get dirty without changing data. E.g. if the timestamp gets updated. Or locks get set and removed. I guess Windows does some allocation without data generation.

Hi, yes, you can pass through the Device with USB passthrough[1] or PCIe passthrough[2]. 1.) https://pve.proxmox.com/pve-docs/pve-admin-guide.html#qm_virtual_machines_settings 2.) https://pve.proxmox.com/wiki/Pci_passthrough

Hi, with PCIe passthrough, you attach the device to the VM. So The VM has 100% control over this device. So if your VM OS and driver are capable of managing multiple windows, it will work.

Hi, Yes, this is possible. I personally would do a backup and snapshot before I start. For Linux VM just detach the vdisk when the VM is offline and attach (double click on it) it back with scsi bus. With Windows, I would recommend an assistant vdisk. 1.) create a new small disk with a scsi...

Hi, swap also happened if memory blocks are not in use.

Hi, bitte mal die netzwerk Konfig posten. Wenn public IP's verwendet werden bitte maskieren. cat /etc/network/interfaces

Hi, first of all, is the bond working? ip -c link show cat /proc/net/bonding/bond0 I miss the hashing policy at the bond level.

I removed the cache mode because this can differ from controller to controller. and I guess the default is the better choice.
