Solutions

1. Correct the <type> value in <typeQuota> to a known storage type (DISK, SSD, ARCHIVE, PROVIDED, NVDIMM).
2. Regenerate the fsimage XML with a version of 'hdfs oiv' that supports the storage types in use.

When it happens

Trigger: Thrown by oiv -r when a <typeQuota> stanza contains a <type> value that is not a valid StorageType.

Common situations: See trigger scenarios.
