I am getting an error when trying to do a snapshot.


lvcreate snapshot 'pve/snap_vm-100-disk-1_test' error: Run `lvcreate --help' for more information.

I am not sure how to trouble shoot this.

What in particular did you do and how does the related configuration (storage, vm, ...) look like?

did you recently install a newer kernel and not yet reboot? In any case, kernel 5.13 is about a year old, please upgrade to a current version and try again.
P.S. Proxmox VE 7 will be end-of-life in 2 weeks, so please consider upgrading to version 8 too: https://pve.proxmox.com/wiki/Upgrade_from_7_to_8
