Michael,
Could you try the test with "gluster volume set testgl cluster.eager-lock off".
If you confirm, we may have to backport the following patch from master/3.5
commit 36b102645ab66d141dcc831e67caa78966d45419

cluster/afr: Disable eager-lock if open-fd-count > 1
Lets say mount1 has eager-lock(full-lock) and after the eager-lock
is taken mount2 opened the same file, it won't be able to
perform any data operations until mount1 releases eager-lock.
To avoid such scenario do not enable eager-lock for transaction
if open-fd-count is > 1. Delaying of changelog piggybacking is
avoided in this situation.
