Description of problem:

I have a gluster partition mounted locally for testing:

[root@testfs ~]# mount -t glusterfs -o acl testfs:/group /mnt/testlocal/

[xpimxwm@testfs testlocal]$ df -h .
Filesystem      Size  Used Avail Use% Mounted on
testfs:/group    20T  466G   20T   3% /mnt/testlocal
[xpimxwm@testfs testlocal]$ mount | grep /mnt/testlocal
testfs:/group on /mnt/testlocal type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,allow_other,max_read=131072)
[xpimxwm@testfs testlocal]$

The get/setfacl tools work, I have added two groups my account belongs to (cnsadm/mriqa):

[xpimxmw@testfs testlocal]$ getfacl /mnt/testlocal/x-test
getfacl: Removing leading '/' from absolute path names
# file: mnt/testlocal/x-test
# owner: 10001
# group: root
user::rwx
group::rwx
group:cnsadm:rwx
group:mriqa:rwx
mask::rwx
other::---
default:user::rwx
default:group::rwx
default:group:mriqa:rwx
default:mask::rwx
default:other::---

[xpimxmw@testfs testlocal]$ groups
cnsadm paradigm nsgc rhode .magicb physics mriqa zzzzz
[xpimxmw@testfs testlocal]$ o

I am neither user 10001 nor in the root group, however the ACL should allow me access:
[xpimxmw@testfs testlocal]$ ls -ld /mnt/testlocal/x-test/
drwxrwx---+ 3 10001 root 4096 Jan  9 16:23 /mnt/testlocal/x-test/
[xpimxmw@testfs testlocal]$ ls /mnt/testlocal/x-test/
ls: cannot open directory /mnt/testlocal/x-test/: Permission denied
[xpimxmw@testfs testlocal]$

I'm somewhat surprised cd works:

[xpimxmw@testfs testlocal]$ cd /mnt/testlocal/x-test/
[xpimxmw@testfs x-test]$ ls
ls: cannot open directory .: Permission denied
[xpimxmw@testfs x-test]$ cd -
[xpimxmw@testfs testlocal]$


I can however access the raw bricks directly:
[xpimxmw@testfs testlocal]$ ls /data/glusterfs/
brick01/ brick02/
[xpimxmw@testfs testlocal]$ ls /data/glusterfs/brick01/
acltest*    physics/     speed/      x-test/
[xpimxmw@testfs testlocal]$ ls /data/glusterfs/brick01/x-test/

[xpimxmw@testfs testlocal]$ getfacl /data/glusterfs/brick01/x-test

# file: data/glusterfs/brick01/x-test
