CACHEINODE {}

NParts (uint32, range 1 to 32633, default 7)
Partitions in the Cache_Inode tree.
Cache_Size(uint32, range 1 to UINT32_MAX, default 32633)
Per-partition hash table size.
Use_Getattr_Directory_Invalidation(bool, default false)
Use getattr for directory invalidation.
Dir_Chunk(uint32, range 0 to UINT32_MAX, default 128)
Size of per-directory dirent cache chunks, 0 means directory chunking is not enabled.
Detached_Mult(uint32, range 1 to UINT32_MAX, default 1)
Max number of detached directory entries expressed as a multiple of the chunk size.
Entries_HWMark(uint32, range 1 to UINT32_MAX, default 100000)
The point at which object cache entries will start being reused.
LRU_Run_Interval(uint32, range 1 to 24 * 3600, default 90)
Base interval in seconds between runs of the LRU cleaner thread.
FD_Limit_Percent(uint32, range 0 to 100, default 99)
The percentage of the system-imposed maximum of file descriptors at which Ganesha will deny requests.
FD_HWMark_Percent(uint32, range 0 to 100, default 90)
The percentage of the system-imposed maximum of file descriptors above which Ganesha will make greater efforts at reaping.
FD_LWMark_Percent(uint32, range 0 to 100, default 50)
The percentage of the system-imposed maximum of file descriptors below which Ganesha will not reap file descriptors.
Reaper_Work(uint32, range 1 to 2000, default 0)
Roughly, the amount of work to do on each pass through the thread under normal conditions. (Ideally, a multiple of the number of lanes.) This setting is deprecated. Please use Reaper_Work_Per_Lane
Reaper_Work_Per_Lane(uint32, range 1 to UINT32_MAX, default 50)
This is the numer of handles per lane to scan when performing LRU maintenance. This task is performed by the Reaper thread.
Biggest_Window(uint32, range 1 to 100, default 40)
The largest window (as a percentage of the system-imposed limit on FDs) of work that we will do in extremis.
Required_Progress(uint32, range 1 to 50, default 5)
Percentage of progress toward the high water mark required in in a pass through the thread when in extremis
Futility_Count(uint32, range 1 to 50, default 8)
Number of failures to approach the high watermark before we disable caching, when in extremis.
