  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: https://forum.proxmox.com/threads/possible-bug-after-upgrading-to-7-2-vm-freeze-if-backing-up-large-disks.109272/ 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...
  4. Backup PVE cluster with 15 nodes and over 650 VMs

    Hi guys, I have a PVE cluster with 15 nodes and over 650 virtual machines, some containers and growing every day. Until now I'm doing backup with one PBS for all nodes, I have a schedule that starts the backup on each node with 15 minutes of delay. Until some time I start to have time out...

  6. Proxmox VE Ceph Benchmark 2020/09 - hyper-converged with NVMe

    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...

    Hello, I have a 5 node cluster with a Dell Compellent sc2020 with 7 SSD disk with mutlipath as storage . On Windows virtual machines when I do a CrystalDisk benchmark we have a little over 22000 IOPS but when I do a fio test on Linux machines never got over 4800 IOPS. So in windows the...
