glusterd: cli command implementation for bitrot scrub status
This patch is backport of: http://review.gluster.org/10231 CLI command for bitrot scrub status will be : gluster volume bitrot <volname> 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 <VOLNAME> followed by statistics of scrubber statistics of individual nodes. sample ouput for single node: Volume name : <VOLNAME> 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. >> Change-Id: I3ed3c7057c9d0c894233f4079a7f185d90c202d1 >> BUG: 1207627 >> Signed-off-by: Gaurav Kumar Garg <ggarg@redhat.com> >> Reviewed-on: http://review.gluster.org/10231 >> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> >> Tested-by: NetBSD Build System <jenkins@build.gluster.org> >> Tested-by: Gluster Build System <jenkins@build.gluster.com> Change-Id: I45ed94e5e0e78a1e007c30eb0b252f74cf3c9187 BUG: 1283881 Signed-off-by: Gaurav Kumar Garg <ggarg@redhat.com> Reviewed-on: http://review.gluster.org/12704 Tested-by: NetBSD Build System <jenkins@build.gluster.org> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>
