    Upgrade from 7.0.10 Kernel 5.11.22-7 to 7.2.4 Kernel 5.15.35-1 Cannot Process Volume Group PVE

    Why Hello There! This evening I performed a regular upgrade to a client's long-standing (~2 years) hyperconverged PVE cluster.

    create storage failed: pvcreate error ... device is too small (pv_min_size) (500)

    Hello, I'm in the process of setting up a HP MSA2040 SAN to work with Proxmox. As I just started using a SAN, I have a little over zero knowledge of these things, so there most probably will be errors in my setup (or terms I don't use correctly). Current status is: - MSA2040 is connected via...

    Add disk creation functionality when using lvm storage

    When using lvm as virtual disk storage it is not enough to pass additional parameters for lvm Example use in console: lvcreate -n vmid-disk-0 --type striped -L 32G -i 4 vg In VG can have e.g. 4 disks (or another number), and the final LV can be created with different parameters, for different...

    lvm related problems (probably bugs)

    Hello Two problems partly related. Problem 1: When you have a vm with a disk on lvm (not in a thin pool) the lv gets deactivated whenever you turn off the vm. This is not such a great idea because if you also have lvmcache enabled the dirty writeback blocks will not be committed from fast to...

    RAW disks -> qcow2 | LVM disks

    Hi there, I have just finished setting up my second homelab host and come to the horrible realisation that my 2 x 2TB and 4TB disks are all LVM and have running VM's on. I tried to take a snapshot, only to realise that I cannot make a snapshot due to it being LVM on the disks. I would like to...
