Trying to first get this working with IPoIB

[root at fpsgluster ~]# ibhosts 
Ca	: 0x00117500007937b2 ports 1 "fpsgluster2 qib0"
Ca	: 0x0011750000792af2 ports 1 "fpsgluster qib0"

I'm able to ping the other box from Infiniband to Infiniband card

Ifconfig uses the ioctl access method to get the full address information, which limits hardware addresses to 8 bytes.
Because Infiniband address has 20 bytes, only the first 8 bytes are displayed correctly.
Ifconfig is obsolete! For replacement check ip.

PING 10.0.4.34 (10.0.4.34) from 10.0.4.35 ib0: 56(84) bytes of data.
64 bytes from 10.0.4.34: icmp_seq=1 ttl=64 time=12.6 ms
64 bytes from 10.0.4.34: icmp_seq=2 ttl=64 time=0.184 ms

/etc/hosts looks correct

[root at fpsgluster2 ~]# cat /etc/hosts | grep ib
10.0.4.35      fpsglusterib
10.0.4.34      fpsgluster2ib

[root at fpsgluster ~]# cat /etc/hosts| grep ib
10.0.4.35      fpsglusterib
10.0.4.34      fpsgluster2ib

I haven't created the new volume yet as I can't get the peer probe to work off the Infiniband card. It's only seeing the NIC cards I currently have it hooked in to.
