Okay, thanks for the clarification. Below are some of the observations I made
for this test case:-
When brick is not changed and kept the way it is in the test case, then the
below happens on s390x:
getfacl /d/backends/brick0/testfile
getfacl: Removing leading '/' from absolute path names
# file: d/backends/brick0/testfile
# owner: root
# group: root
user::rw-
group::r--
other::r--

Whereas, on x86,
getfacl /d/backends/brick0/testfile
getfacl: Removing leading '/' from absolute path names
# file: d/backends/brick0/testfile
# owner: root
# group: root
user::rw-
user:14:r--
group::r--
mask::r--
other::r--

Since the setfacl command fails,the above behavior is seen. When I checked the
logs,
On s390x, this is shown:-
D [MSGID: 0] [client-rpc-fops_v2.c:887:client4_0_getxattr_cbk]
0-patchy-client-0: remote operation failed: No data available. Path: /testfile
(fa921dc9-41a3-4fad-9fab-2c0933e54e38). Key: system.posix_acl_access
On x86, this is shown:-
D [MSGID: 0] [nfs3-helpers.c:1660:nfs3_log_fh_entry_call] 0-nfs-nfsv3: XID:
a2d2141c, LOOKUP: args: FH: exportid d7f43849-b25a-49d2-8084-aefb8d7797f2, gfid
00000000-0000-0000-0000-000000000001, mountid
8d32c8d1-0000-0000-0000-000000000000, name: libacl.so.1

Therefore, I tried remounting acl in the test case and even tried adding acl in
/etc/fstab in the following ways:-
In the test case-------> mount -o remount,acl /
In /etc/fstab----------> /dev     /boot/zipl  ext2  defaults,acl        0  2

However, the test case still fails. So, can you please provide us with some
details as to what happens when the commands;
EXPECT_WITHIN $NFS_EXPORT_TIMEOUT "1" is_nfs_export_available;
TEST mount_nfs $H0:/$V0 $N0 nolock
are run in the test case.
