Question

While performing the volume status checks, if the status is insufficient data, what does it mean?

Answer 1

If the check fails, the overall status is impaired . If the status is insufficient-data, then the checks may still be taking place on your volume at the time. ... This means that your volume has been affected by an issue with the underlying host, has all I/O operations disabled, and may have inconsistent data.
