  1. Proxmox Backup Server 2.2 available

    Finaly I had to downgrade to 2.1-8 because I can't upgrade my PVE nodes to 7.2 now. There is this bug with backing up large files: And I can't asume that risk.

  3. Backup PVE cluster with 15 nodes and over 650 VMs

    Thanks for your answer @SINOS I think get better hardware is only a patch, I need horizontal scalability. The number of virtual machines grow every day, is imposible grow with brute force and for this is necessary a big budget. If PBS can't grow in horizontal is only for small business cluster...

    Hi, If we make 4 OSD on each NVME disk, will we get more performance or this is irrelevant? Thanks in advance.
  7. iSCSI message

    I gave up looking for a solution to this, I saw that it was not a mistake and as I had no more time to devote to it I gave it up. Today in my company we no longer use those Compellent Storage arrays, we have moved on to Ceph. Sorry I can't help more.

  11. [SOLVED] Linux virtual machines poor IO perfomance over SSD

    Thank you for your answers. Finally I managed to get the performance of the SSD disks by changing the configuration of execution of fio. Using this config: [global] bs=4k ioengine=libaio iodepth=32 size=4g direct=1 runtime=60 directory=/home filename=ssd.test.file [seq-read] rw=read stonewall...
