How do you determine the zfs_vdev_cache_size current value?
How do you ascertain the current zfs vdev cache size (e.g.
zfs_vdev_cache_size) via mdb or kstat or any other cmd?
Thanks in advance,
Brad

vdev cache - comments in the source
...o zfs-code,
http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/fs/zfs/vdev_cache.c
72 * All i/os smaller than zfs_vdev_cache_max will be turned into
73 * 1<<zfs_vdev_cache_bshift byte reads by the vdev_cache (aka software
74 * track buffer). At most zfs_vdev_cache_size bytes will be kept in each
75 * vdev''s vdev_cache.
While it is mentioned in lines 46, 47 that it does affect only metadata
I/O, imho for clarity it should also be mentioned in lines 72-75.
I guess http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/fs/zfs/zio...
