Description Ravishankar N 2014-07-03 11:44:39 UTC
Description of problem:

    glfsh_validate_replicate_volume() used to check if AFR was the parent of
    all client xlators present in the graph. This need not always be true, for
    example, for user-serviceable-snapshots where the parent of snapd-client is
    snapview-client.

    heal: fix the way we check the presence of AFR in glfsheal
    
    Problem:
    glfsh_validate_replicate_volume() used to check if AFR was the parent of
    all client xlators present in the graph. This need not always be true, for
    example, for user-serviceable-snapshots where the parent of snapd-client is
    snapview-client.
    
    Fix:
    glfsh_validate_replicate_volume() returns true if atleast one client
    xlator has AFR as its parent. Also, AFR need not be its immediate
    parent, but be present somewhere in its parent ancestry.

The first (and last?) Beta for GlusterFS 3.5.2 has been released [1]. Please verify if the release solves this bug report for you. In case the glusterfs-3.5.2beta1 release does not have a resolution for this issue, leave a comment in this bug and move the status to ASSIGNED. If this release fixes the problem for you, leave a note and change the status to VERIFIED.

Packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update (possibly an "updates-testing" repository) infrastructure for your distribution.
