NAME¶
ndctl-check-labels - determine if the given dimms have a valid namespace index blockSYNOPSIS¶
ndctl check-labels <nmem0> [<nmem1>..<nmemN>] [<options>]
DESCRIPTION¶
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.OPTIONS¶
<memory device(s)>One or more nmemX device names. The keyword
all can be specified to operate on every dimm in the system, optionally
filtered by bus id (see
--bus= option).
-b, --bus=
Limit operation to memory devices (dimms) that are on the
given bus. Where bus can be a provider name or a bus id number.
-v
Turn on verbose debug messages in the library (if ndctl
was built with logging and debug enabled).
