What: /sys/block/<disk>/bcache/writeback_running Date: November 2010 Contact: Kent Overstreet <kent.overstreet@gmail.com> Description: For backing devices: when off, dirty data will not be written from the cache to the backing device.

What: /sys/block/<disk>/bcache/writeback_delay Date: November 2010 Contact: Kent Overstreet <kent.overstreet@gmail.com> Description: For backing devices: In writeback mode, when dirty data is written to the cache and the cache held no dirty data for that backing device, writeback from cache to backing device starts after this delay, expressed as an integer number of seconds. What: /sys/block/<disk>/bcache/writeback_percent Date: November 2010 Contact: Kent Overstreet <kent.overstreet@gmail.com> Description: For backing devices: If nonzero, writeback from cache to backing device only takes place when more than this percentage of the cache is used, allowing more write coalescing to take place and reducing total number of writes sent to the backing device. Integer between 0 and 40. What: /sys/block/<disk>/bcache/synchronous Date: November 2010 Contact: Kent Overstreet <kent.overstreet@gmail.com> Description: For a cache, a boolean that allows synchronous mode to be switched on and off. In synchronous mode all writes are ordered such that the cache can reliably recover from unclean shutdown; if disabled bcache will not generally wait for writes to complete but if the cache is not shut down cleanly all data will be discarded from the cache. Should not be turned off with writeback caching enabled.
