Special Class Metadata Reserve Pct

Type: integer

Percentage of PERFORMANCE tier space reserved for metadata.

Beyond that threshold data falls back to the REGULAR tier. Corresponds to the ZFS kernel parameter zfs_special_class_metadata_reserve_pct (default: 25).

Value must be greater or equal to 10 and lesser or equal to 30
