Description of problem: I was trying to debug regression failures on [1]. Note that patch [1] only disables usage of anonymous fds on readv. So, I tried the same test disabling performance.open-behind [root@ glusterfs]# git diff diff --git a/tests/bugs/snapshot/bug-1167580-set-proper-uid-and-gid-during-nfs-access.t b/tests/bugs/snapshot/bug-1167580-set-proper-uid-and-gid-during-nfs-access.t index 3776451..cedf96b 100644 --- a/tests/bugs/snapshot/bug-1167580-set-proper-uid-and-gid-during-nfs-access.t +++ b/tests/bugs/snapshot/bug-1167580-set-proper-uid-and-gid-during-nfs-access.t @@ -79,6 +79,7 @@ TEST $CLI volume start $V0 EXPECT_WITHIN $NFS_EXPORT_TIMEOUT "1" is_nfs_export_available TEST glusterfs -s $H0 --volfile-id $V0 $M0 TEST mount_nfs $H0:/$V0 $N0 nolock +TEST $CLI volume set $V0 performance.open-behind off # Create 2 user user1=$(get_new_user) With the above change, I can see consistent failures of the test just like observed in [1].

However, Rafi has some analysis which points to issue not being in test itself but a different component in code. Rafi will give reasoning on why he thinks so and will change the component accordingly. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3.
