VM not a bootable disk

[jackDante]

Hi, thanks in advance.
I made a VM's clone from one node to another one (in my cluster).

• The process created a new logical volume in my node, however my VM does not boot correclty as you can see in the image (posted).
• I have my logical volume /dev/main/vm-303-disk-0, but I cannot understand what's wrong.
• I can make it available using >lvchange -ay /dev/main/vm-303-disk-0, but this does not solve my VM'booting problem!
  
  Thanks

The new node situation is::

Hi,

please share the configuration of the vm by either screenshot of Hardware and Options or by running qm config 303 in the PVE cli

Mmh, don't know if the following would help but you are missing the thin-pool ... compare to orig path with shown by "lvs" the "t" for Attr :
pv: real disk -> vg: pve -> lv: data -> vdisk: vm-103-disk-0
pv: real disk -> vg: main -> lv: % -> vdisk: vm-303-disk-0

Here the VM 303 configuration (see image "5"):

boot: order=scsi0;ide2;net0
cores: 16
cpu: x86-64-v2-AES
ide2: none,media=cdrom
memory: 16384
meta: creation-qemu=8.1.5,ctime=1734364410
name: 4A-uel03
net0: virtio=BC:24:11:6B:94:4C,bridge=vmbr1,firewall=1
numa: 0
ostype: l26
scsi0: main:vm-303-disk-0,iothread=1,size=500G
scsihw: virtio-scsi-single
smbios1: uuid=0199234a-a435-4ba8-8c35-539f658d1237
sockets: 1
vmgenid: 26f5294f-ed25-479a-8fbf-6a5920fce708

I followed this steps, maybe it's not the best one:

1. I have a Cluster with 4 Nodes.
   1. First of all, I creted Volume Group "main" on /dev/sda (See image "2")
2. First I created Node1, VM101 (ubuntu) and then I cloned VM101 (renamed in VM202) to the new Node2.
3. Then I cloned VM202 to Node3 and so on.
4. At the end of the story, only the VMs in Node1 and 2 are able to boot correctly...and I didn't understand why yet.

I'm not using the thin-pool.


Thanks
