    cluster/ec: Prevent double unwind
    
    Problem:
    1) ec_access/ec_readlink_/ec_readdir[p] _cbks are trying to recover only from
    ENOTCONN.
    2) When the fop succeeds it unwinds right away. But when its
    ec_fop_manager resumes, if the number of bricks that are up is less than
    ec->fragments, the the state machine will resume with -EC_STATE_REPORT which
    unwinds again. This will lead to crashes.
    
    Fix:
    - If fop fails retry on other subvols, as ESTALE/ENOENT/EBADFD etc are also
    recoverable.
    - unwind success/failure in _cbks

Comment 5 Nagaprasad Sathyanarayana 2015-10-25 15:01:13 UTC

Fix for this BZ is already present in a GlusterFS release. You can find clone of this BZ, fixed in a GlusterFS release and closed. Hence closing this mainline BZ as well.

Comment 6 Niels de Vos 2016-06-16 13:09:29 UTC

This bug is getting closed because a release has been made available that should address the reported issue. In case the problem is still not fixed with glusterfs-3.8.0, please open a new bug report.

glusterfs-3.8.0 has been announced on the Gluster mailinglists [1], packages for several distributions should become available in the near future. Keep an eye on the Gluster Users mailinglist [2] and the update infrastructure for your distribution.
