From 097e131481d25e5b1f859f4ea556b8bf56155472 Mon Sep 17 00:00:00 2001 From: Gaurav Kumar Garg Date: Wed, 25 Mar 2015 18:07:24 +0530 Subject: glusterd: cli command implementation for bitrot scrub status CLI command for bitrot scrub status will be : gluster volume bitrot scrub status Above command will show the statistics of bitrot scrubber. Upon execution of this command it will show some common scrubber tunable value of volume followed by statistics of scrubber statistics of individual nodes. sample ouput for single node: Volume name : State of scrub: Active Scrub frequency: biweekly Bitrot error log location: /var/log/glusterfs/bitd.log Scrubber error log location: /var/log/glusterfs/scrub.log ========================================================= Node name: Number of Scrubbed files: Number of Unsigned files: Last completed scrub time: Duration of last scrub: Error count: ========================================================= This is just infrastructure. list of bad file, last scrub time, error count value will be taken care by http://review.gluster.org/#/c/12503/ and http://review.gluster.org/#/c/12654/ patches.
