emergency mode after fstab edit

[kpwn]

I created a filesystem (ext4) on my newly created logical volume. i can mount it using mount /dev/mapper/HDD-ISOs /mnt/lvm/ISOs/.
It works just fine.
if i try using fstab to automount it the system boots into emergency mode. fstab entry:
/dev/mapper/HDD-ISOs /mnt/lvm/ISOs/ ext4 defaults 0 0

if i comment that line in fstab the system boots again so it is definately the problem.
When the system is bootet up and i uncomment the line in fstab i can run mount -a without any erros. The files are also there so the line in fstab should work. Why is it not working on system startup?

Why is it not working on system startup?

Maybe fstab trys to mount the ext4 before the LVM has finished loading?

how could i verify or circumvent that?

If you weren't running LVM before, you might be missing LVMsupport in your initramfs. Is this a default Proxmox Hypervisor machine?

Its a default proxmox hypervisor. I recently freshly installed it. I think its version 6.4.4 and it uses LVM for its boot disk (that is default as far as i know)
