@ayushtkn , in fact we don't have to hold this for HDFS-15660 as vinay said,
the codes here is to fix the specific issues of NVDIMM, to avoid operations
which related with storage type during rollingupgrade, to keep the orinal of
storage type to make sure the editLog/fsimage works after restart namenode.
IIUC, the miniCompatLV of namenodelayout version is introduced to make sure to
refuse operations while rollingupgrade, so I think the approach is appropriate
for the situation.

> HDFS-15025 adds a new storage Type NVDIMM, changes the ordinal() of the enum
> of StorageType. And, setting the quota by storageType depends on the
> ordinal(), therefore, it may cause the setting of quota to be invalid after
> upgrade.
