Hi David,

Could you also share the brick logs from the affected volume? They're
located at
/var/log/glusterfs/bricks/<hyphenated-path-to-the-brick-directory>.log.

Also, could you share the volume configuration (output of `gluster volume
info <VOL>`) for the affected volume(s) AND at the time you actually saw
this issue?

-Krutika
