[SOLVED] Error while creating VM

[n3x_proxmox]

Hi,

Recently I have just setup my first Proxmox hypervisor on a Intel NUC.

Had setup a secondary 1TB SSD with two partition of 500GB each.

Initially I managed to create a few VMs and delete them off just for testing, but suddenly now I encountered an error whenever I try to create a VM.

Error: (See attached screenshot)

WARNING: ext4 signature detected on /dev/SATA1/vm-100-disk-0 at offset 1080. Wipe it? [y/n]: [n]
  Aborted wiping of ext4.
  1 existing signature left on the device.
  Failed to wipe signatures on logical volume SATA1/vm-100-disk-0.
TASK ERROR: unable to create VM 100 - lvcreate 'SATA1/vm-100-disk-0' error:   Aborting. Failed to wipe start of new LV.

Hopefully someone here can share some experience on how to resolve and overcome this issue.

Thanks!

hi,

it looks like you have orphan disks from the old VMs, maybe they weren't removed properly. how did you delete the VMs?

and which kind of storage is this? lvm or lvmthin?
for lvm you can set saferemove option to zero out the disks when deleted [0]

otherwise just deleting the orphan disks should get things working again -- you can test also making a new VM with a different ID (pick something you haven't used before) and that should also work

Hi, thanks for replying.

I delete the VMs via the GUI, shutdown first then More > Remove

it's LVM storage.

Somehow I managed to resolve the issue by adding the Proxmox no-subscription repository, update and reboot.

Dude cheers, updating worked for me too.

usually it works to delete the lvm via cli by checking via

• lvs
• pvs
• vgs

and the commands to remove them:

• lvremove
• pvremove
• vgremove

no reboot needed. also sgdisk -Z /dev/sdX after removing the lvm is good way to get a "clean" disk.

I joined the forums for this exact issue. Adding the repo, updating and rebooting fixed it for me too.
