Major issues

  1. Expanding a gluster volume that is sharded may cause file corruption

    • Sharded volumes are typically used for VM images, if such volumes are expanded or possibly contracted (i.e add/remove bricks and rebalance) there are reports of VM images getting corrupted.
    • The last known cause for corruption #1465123 is still pending, and not yet part of this release.
