Detailed Description
File system statistics.
Field Documentation
| bool fds_stat_t::corruption |
Filesystem corruption has been detected.
One or more corrupted records were detected. FDS will heal the filesystem automatically next time garbage collection is run, but some data may be lost.
- Note
- : This flag is unrelated to CRC failures.
| uint16_t fds_stat_t::freeable_words |
The largest number of words that can be reclaimed by garbage collection.
The actual amount of space freed by garbage collection might be less than this value if records are open while garbage collection is run.
| uint16_t fds_stat_t::largest_contig |
The largest number of free contiguous words in the file system.
This number indicates the largest record that can be stored by FDS. It takes into account all reservations for future writes.
