Do the mount or df commands show the MDT as mounted? If so, the -11 error can be ignored,
I think, as a side-effect of not having any OSTs connected to the file system. For first
time mounts, you have to mount the MGT and MDTs before the OSTs, but you get this
side-effect.

Subject: [HPDD-discuss] An error and some questions
Good afternoon,
I'm in the process of standing up a new lustre 2.5.3 file system, and
have been getting a strange error when I mount the mds/mdt.
I'm using CentOS 6.5, with the stock infiniband, lustre 2.5.3, and a
logical volume (to allow for snapshots and backups). The module for lnet
contains the following "options lnet networks=tcp0(em1),o2ib0(bond0)"
Though the mds/mdt seems to mount I see the following error...
~] mount -t lustre /dev/lustrepool/lustrevol /mdt
~] dmesg
LDISKFS-fs (dm-1): mounted filesystem with ordered data mode.
quota=on. Opts:
Lustre: lustre-MDT0000: used disk, loading
