    Hi all, while working on a small cluster with shared storage on iSCSI, I've noticed a problem with multipath that I can consistently reproduce.

  9. Full node hangs for seconds at CT/VM creation/deletion/bootup/backup (mdraid1+LVM)

    Hello, the title describes the problem pretty well. It's a single node with no cluster or any "exotic" external storage.

  13. How to better use disks on new setup of PVE 4.1?

    Hello, For years I lived with the idea that the only underling storage for PVE should be hardware-backed array of disks, which can self-heal, self-cached, and which is guaranteed to be always-in-good-shape. But now I see recent PVE versions are with ZFS out of box (but as I played with some of...
