I think you met the issues I mentioned in:
http://jira.whamcloud.com/browse/ORNL-3
I have made patch for it and in testing.
Before the patch landed, you can mount MDT with "-o acl" or "-o noacl"
explicitly to avoid these confused messages.

Hi all,
I recently loaded the following on my testbed to try out Lustre 2.0:
· One MDS -- RHEL 54, Lustre 2.0
o mkfs.lustre --fsname=lufs --reformat --mgs --mdt --param
lov.stripesize=25M --param lov.stripecount=1 /dev/sda2
o /etc/fstab = /dev/sda2 /lustre1-mgs-mds lustre
rw,noauto,_netdev 0 0
· One OSS -- RHEL 54, Lustre 2.0
o mkfs.lustre --fsname=lufs --reformat --ost
--mgsnode=10.103.34.42@o2ib0 /dev/sdb
o mkfs.lustre --fsname=lufs --reformat --ost
--mgsnode=10.103.34.42@o2ib0 /dev/sdc
o /etc/fstab = /dev/sdb /lustre1/ost1 lustre
rw,noauto,_netdev 0 0
o /dev/sdc /lustre1/ost2 lustre
rw,noauto,_netdev 0 0
· One Client -- RHEL 54, Lustre 2.0
o /etc/fstab = 10.103.34.42@o2ib0:/lufs /lustre1_fifo
lustre rw,noauto,_netdev 0 0
/lustre-mgs-mds, /lustre1/ost1,2 mounted OK on MDS and OSS.
/lustre1_fifo mounted OK with Client. So far so good.
On Client, "cd /" and performed a "ls --l". The following messages
immediately showed up:
· On Client
o Jan 18 14:04:19 bg8mo33sn kernel: LustreError: 11-0: an error
occurred while communicating with 10.103.34.42@o2ib. The mds_getxattr
operation failed with -95
· On MDS
o Jan 18 14:04:19 bg8mo33lm kernel: LustreError:

lens 448/328 e 0 to 0 dl 1295359465 ref 1 fl
Interpret:/ffffffff/ffffffff rc -95/-1
All IBs between all nodes are alive and seeing each other with no problem.
The client also NFS exports /lustre1_fifo via:
· /etc/exports = /lustre1_fifo testhost1(rw,sync,no_root_squash)
After testhost1 mounted /lustre1_fifo and attempt to "mkdir test"
under it, the same error messages from above showed up on the MDS and
the client. "-95" as "Operation not supported on transport endpoint"
but what does it mean here in this context.
The same MDS/OSS/Client setup/arrangements ran fine on RHEL 5.3 and
Lustre 1.8.1.1 with no errors.
Appreciate any help/insight. Thanks.
