Problem with vgscan

[M@ario]

Hello!

I just added another cluster node to my 3 node proxmox enviroment. When I clicked on the storage menu vgscan started to run with 100% CPU Load on that node. I had to kill the process manually to make the node respond again. I then tried a manual vgscan -vvvv. This is now stuck too (witch 100% CPU Load) at

#device/dev-io.c:439         Opened /dev/mapper/VM_Data-vm--418--disk--2 RW O_DIRECT
#device/dev-io.c:134         /dev/mapper/VM_Data-vm--418--disk--2: block size is 4096 bytes
#label/label.c:160       /dev/mapper/VM_Data-vm--418--disk--2: lvm2 label detected

I assume that somehow the LV got corrupted. But the strange thing is that the VM 418 is working without problems.
Anyone got an idea how to proceed/repair the LV?
