Snapshots folder - Invalid argument

[inmar tzemach]

Hi

I am running Prometheus as Linux container.

I created some snapshots data with the api :

curl -XPOST http://localhost:9090/api/v1/admin/tsdb/snapshot

The snapshot folder was created successfully.

My problem is that when I am trying to copy or zip the folder I am getting the error of 

cp: cannot open '20220511T121232Z-57f36c7e91baff60/01G2SCD9E9V9HWHVXYC2J1XFYS/chunks/000001' for reading: Invalid argument

Removing the folder is allowed.

After stopping the Prometheus container, the errors stopped so I am guessing the Prometheus kept some links to the snapshots.

Is there any workaround for this?

Thanks
