Hey,
Please provide the glustershd log from all the nodes and client logs on the node from where you did the lookup on the file to resolve this issue.

Regards,
Karthik

        Hi, glusterfs expert
        When I test with
            glusterfs version 3.12.3 I find it quite often that
            sometimes, there are entry remains in gluster volume heal
            <vol-name>info output for long time,
            it does not disappear until you visit it from the mount
              point, is this normal?
