-Zoned Filesystems
-=================
-
-For zoned file systems, the following attributes are exposed in:
-
- /sys/fs/xfs/<dev>/zoned/
-
- max_open_zones (Min: 1 Default: Varies Max: UINTMAX)
- This read-only attribute exposes the maximum number of open zones
- available for data placement. The value is determined at mount time and
- is limited by the capabilities of the backing zoned device, file system
- size and the max_open_zones mount option.
-
- zonegc_low_space (Min: 0 Default: 0 Max: 100)
- Define a percentage for how much of the unused space that GC should keep
- available for writing. A high value will reclaim more of the space
- occupied by unused blocks, creating a larger buffer against write
- bursts at the cost of increased write amplification. Regardless
- of this value, garbage collection will always aim to free a minimum
- amount of blocks to keep max_open_zones open for data placement purposes.
