Can you share the snapshot yaml and also share the lvm volume yaml you are using to create the snapshot?
Here my yaml, i hope it helps:

@benn0r could you share the controller logs and the daemonset logs of the node where volume is present?

What is the k8s and LVM-LocalPV version you are using?
It seems like CRDs are not updated in your case. How did you install it?
What is the k8s and LVM-LocalPV version you are using?
openebs/lvm-driver:0.7.0 -> is that what you asked? Kubernetes Version: v1.22.7 (K3s) -> installed with Rancher on Photon OS
It seems like CRDs are not updated in your case. How did you install it?
I installed openebs with the Partner Chart from Rancher: https://github.com/rancher/partner-charts/tree/main-source/charts/openebs/openebs/3.0.0
I can see now that openebs/lvm-driver:0.9.0 is already relased. Should i try to upgrade?
@benn0r can you install 0.9.0 and try? Here is the helm chart location https://github.com/openebs/lvm-localpv/tree/develop/deploy/helm/charts.
The CRDs here https://github.com/rancher/partner-charts/tree/main-source/charts/openebs/openebs/3.0.0 are outdated. Please install it from the LVM-LocalPV repo.
The CRDs here https://github.com/rancher/partner-charts/tree/main-source/charts/openebs/openebs/3.0.0 are outdated. Please install it from the LVM-LocalPV repo.
You are right, thanks a lot. WIth openebs 3.2.0 chart and updating the crds it works now!
What steps did you take and what happened: Followed this guide: https://github.com/openebs/lvm-localpv/blob/develop/docs/snapshot.md
What did you expect to happen: Snapshot should be created

Anything else you would like to add:
I can create snapshots manually without any problems:
lvcreate --size 1G --snapshot --name my-name /dev/tank/pvc-01f43051-83af-409f-922a-9a3653351aad
In the log from the controller i see this name for the snapshot:snapshot-44c1fe7d-f202-4af5-b56e-69081360e95e
. When trying to manually create this snapshot i get this error:Names starting "snapshot" are reserved. Please choose a different LV name.
Could this be the issue? How to fix that?I have checked all logs but i cannot find any useful information about why creating the snapshot fails
