With the increase in SSD/NVMe memory prices worldwide, this type of memory tends to significantly increase the cost of backup infrastructure. Is there any possibility that the Proxmox Backup Server project could rethink the use of HDDs and design a solution for better performance in this...

Hi. I will test another approach. I will install a windows and use the gdrive official client for. Then, share the gdrive using smb protocol and access by proxmox backup server (mounting like smb share and add it to datastore). I think the performance and verification of backups will be better...

Hi. Is the Offline Replication between two Data Centers working ? If yes, can someone give the feedback ? Best Regards.

I read about the thin provisioning. Solved.

Hi. I have a situation. A virtual machine has 1450GB disk. When i active the replication, the size grow very much: NAME USED AVAIL REFER MOUNTPOINT SAS0/vm-701-disk-0 2.44T 2.13T 1.01T - # zfs list -t snapshot NAME...

Hi. Is there a file inside proxmox that I can edit and, when the OS type is Windows, it will automatically add hv-tlbflush to the processor?

You are using nvme, you can try mq-deadline. De none is the default for nvme disks. But is uncommon you have this problems on nvme.

UPDATE: NOOP: A simple scheduler that operates on a FIFO queue without any additional reordering, ideal for devices that already have their own scheduler, such as SSDs. Deadline: Aims to minimize the response time for any I/O operation, giving each operation a deadline before which it must be...

Yes. What work for me: SSD. Some ssds don´t really is 4k. When you format SSD in ZFS the standard is ashift 12. I turn to 9. Raid controllers: Some raid controllers just don´t got to the zfs the performance need for write. So, So when zfs is faster at writing than disk, a timeout or lock...

Good morning everybody. I planned the following scenario and would like to know if anyone here has set up something similar or if something in the services has any limitations. I will have two OmniOS servers, with ZFS and using COMSTAR for iscsi. The two storage servers have several Intel...

Thanks. I just remove the old node using the pvecm delnode (this updates the corosync) and remove from corosync the two_node and wait_all paramters. Then pvecm add on each new node and everything goes well. Best regards.

So, this is the problem. I have more servers to add but I can't. The master server had a problem and I only had the secondary one. I can't add new servers. So simplifying the question: can I delete the master and the secondary becomes the main? Then i can add more servers.

Hello everybody. I have the following problem. There were 2 clustered servers (two_nodes: 1) The first server had a problem and was shut down. However, this first server was the master, where the cluster was created. Is there any way to make the second server master? When i click on cluster, a...
