Validate snapshot name

[tushar1701]

Need some clarification

During csi-sanity checks , got the following failure:-

[Fail] CreateSnapshot [Controller Server] [It] should succeed when creating snapshot with maximum-length name

Is it documented somewhere about the maximum length value? How can we incorporate this on our CSI driver?

is this piece of information authentic and can be considered?

Snapshot name must begin with a letter or number, end with a letter, number or underscore,
and may contain only letters, numbers, underscores, periods, or hyphens.
