ndctl-check-labels - determine if the given dimms have a valid namespace index block
ndctl check-labels <nmem0> [<nmem1>..<nmemN>] [<options>]
The namespace label area is a small persistent partition of capacity available on some NVDIMM devices. The label area is used to resolve aliasing between pmem and blk capacity by delineating namespace boundaries. In addition to checking if a label area has a valid index block, running this command in verbose mode reports the reason the index block is deemed invalid.
