Comment 2 Amar Tumballi 2019-05-27 16:29:22 UTC

This got fixed in glusterfs-5.5 (or glusterfs-6.1). Please upgrade.

Comment 3 ryan 2019-05-28 10:05:54 UTC

Hi Amar,

Has this been back-ported to Gluster 4?

Comment 4 Amar Tumballi 2019-05-28 10:17:39 UTC

Ryan, considering there was no release of 4.1.x branch, this was not backported. Best thing is to upgrade to 5.6 or 6.1 right now.
