[Gluster-users] hanging "df" (3.1, infiniband)

I believe it's OFED but I suppose I'm not certain.  The initial
installation of these systems included IB support which was installed
by the vendor along with the OS (CentOS 5.5) and which was turned off
("chkconfig openibd off") when delivered.

I don't seem to have an "ofed_info" command.  Also, my openib.conf is
in /etc/ofed rather than /etc/infiniband.  It contains:

[root at storage0 ~]# cat /etc/ofed/openib.conf
# Load IPoIB
IPOIB_LOAD=yes
# Load SDP module
SDP_LOAD=yes
# Load the RDS protocol driver
RDS_LOAD=yes
# Load SRP module
SRP_LOAD=yes
# Load iSER module
ISER_LOAD=yes
# Should we modify the system mtrr registers?  We may need to do this if you
# get messages from the ib_ipath driver saying that it couldn't enable
# write combining for the PIO buffs on the card.
FIXUP_MTRR_REGS=no
