Hi Bart.
any advice on using this fix with MD raid 1? a guide or site you know of?
ive compiled ubuntu 13.04 to kernel 3.6.11 with OFED 2 from Mellanox, and it
works ok, performance is a little better with SRP. Some packages dont seem
to work, ie srptools and IB-diags some commands fail, which looks like those
tools havenet been tested with 3.6.11? or updated.
Ive tried using DRBD with pacemaker Stonith etc (which also works on 3.6.11)
but it only works with iSCSI over IPOIB. ie virtual nic with mounted LVM
using scst to present file i/o. and pacemaker to fail over the VIP to node
2. But OFED 2 doesnt seem to support SDP to have to rep via IPOIB which is
slow even over dedicated IB_IPOIB nic. IE DRBD rep is 200MB/s
Any help or direction would be greatfull.
Cheers
Bruce McKenzie
