Adding ChangeTimeRecorder(CTR) Xlator to GlusterFS
**********************************************************************
ChangeTimeRecorder(CTR) Xlator |
**********************************************************************
ChangeTimeRecorder(CTR) is server side xlator(translator) which sits
just above posix xlator. The main role of this xlator is to record the
access/write patterns on a file residing the brick. It records the
read(only data) and write(data and metadata) times and also count on
how many times a file is read or written. This xlator also captures
the hard links to a file(as its required by data tiering to move
files).
CTR Xlator is the consumer of libgfdb.
To Enable/Disable CTR Xlator:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gluster volume set <volume-name> features.ctr-enabled {on/off}
To Enable/Disable Frequency Counter Recording in CTR Xlator:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gluster volume set <volume-name> features.record-counters {on/off}
