[Novalug] Trying to access my own disk--Identifier removed

Greetings List!

I have a disk (tech specs Lustre fs) that I have mounted on my system. 
  It works great!  Zippy.   No errors.    Uhh----as long as you are 
"root".   All other users get an "Identifier removed" error.

selinux is disabled.

I have other lustre disks all of which are still fine.
The problem disk is a new one.

As root:
ic-mds1@o2ib:/crew8    76T  208G   72T   1% /crew8
[root@crew01 ~]# cd /crew8
[root@crew01 crew8]# ls -l

Happy Happy Joy Joy!!

HOWEVER, as user "larkoc":
[larkoc@crew01 ~]$ cd /crew8
[larkoc@crew01 crew8]$ ls
ls: .: Identifier removed
[larkoc@crew01 crew8]$ ls -l
ls: .: Identifier removed
[larkoc@crew01 crew8]$ pwd
/crew8
[larkoc@crew01 crew8]$ cd larkoc
[larkoc@crew01 larkoc]$ ls
ls: .: Identifier removed
[larkoc@crew01 larkoc]$ cp /home/larkoc/megCBF/CBF.phone.dir.txt .
cp: cannot stat `./CBF.phone.dir.txt': Identifier removed
[larkoc@crew01 larkoc]$ ls
ls: .: Identifier removed
[larkoc@crew01 larkoc]$ ls -la
ls: .: Identifier removed

My Google search yielded only two results for the string "Identifier 
removed";  neither one had the string together in the doc.  I know this 
is a permission issue.  My "lasttr" shows no hidden attributes (like 
immutable and friends).

Have any of you seen this before?   How can I get access to this disk 
with current perms 775 on the dirs?

All suggestions genuinely appreciated.
