cluster/afr: [Feature] Command implementation to get heal-count
Currently to know the number of files to be healed, either user has to go to backend and check the number of entries present in indices/xattrop directory. But if a volume consists of large number of bricks, going to each backend and counting the number of entries is a time-taking task. Otherwise user can give gluster volume heal vol-name info command but with this approach if no. of entries are very hugh in the indices/ xattrop directory, it will comsume time. So as a feature, new command is implemented. Command 1: gluster volume heal vn statistics heal-count This command will get the number of entries present in every brick of a volume. The output displays only entries count. Command 2: gluster volume heal vn statistics heal-count replica 192.168.122.1:/home/user/brickname Here if we are concerned with just one replica. So providing any one of the brick of a replica will get the number of entries to be healed for that replica only. Example: Replicate volume with replica count 2. Backend status: -------------- [root@dhcp-0-17 xattrop]# ls -lia | wc -l 1918 NOTE: Out of 1918, 2 entries are <xattrop-gfid> dummy entries so actual no. of entries to be healed are 1916. [root@dhcp-0-17 xattrop]# pwd /home/user/2ty/.glusterfs/indices/xattrop Command output: -------------- Gathering count of entries to be healed on volume volume3 has been successful Brick 192.168.122.1:/home/user/22iu Status: Brick is Not connected Entries count is not available Brick 192.168.122.1:/home/user/2ty Number of entries: 1916 Change-Id: I72452f3de50502dc898076ec74d434d9e77fd290 BUG: 1015990 Signed-off-by: Venkatesh Somyajulu <vsomyaju@redhat.com> Reviewed-on: http://review.gluster.org/6044 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
