`gluster volume heal <vol-name> split-brain' changes required for entry-split-brain
Last modified: 2016-09-17 08:11:43 EDT
Description of problem: ------------------------ `gluster volume heal <vol-name> split-brain' command today has 2 arguments: bigger-file and source-brick. In case of a directory entry split-brain, the argument bigger-file is not meaningful and should not be accepted. The user needs to be notified that this option cannot be used with directories. Currently, this argument causes entry split-brain to be healed by conservative merge, without any complaints. For the source-brick argument, the user should be notified that it is conservative merge that will be performed for the directory in question and the heal should happen. Version-Release number of selected component (if applicable): -------------------------------------------------------------- glusterfs-3.7.1-3.el6rhs.x86_64 How reproducible: ------------------ Always Steps to Reproduce: -------------------- 1. On a directory in entry split-brain, run the `gluster volume heal <vol-name> split-brain' command with each of the 2 arguments. Actual results: ---------------- Heal happens in both cases without notifying the user, as explained in description. Expected results: ------------------ User should be notified in case the bigger-file argument is used to heal directory entry split-brain, that this is not applicable to directories. In case of source-brick argument, perform conservative merge and notify the user accordingly. Additional info:
