I currently have two AoE SANs deployed and they both have the same problem. So I must be missing something somewhere. I originally wrote about this last November:
http://www.mail-archive.com/aoetools-discuss@lists.sourceforge.net/msg00136.html And never got the problem solved. I also did not get around to trying the patch Ed suggested. But I have a feeling there has got to be something I am doing wrong in the setup here. Performance didn't really matter much on that deployment at the time although it is becoming more important and I have just set up a second SAN with the same issue where I really do need it to perform. I have set up AoE SANs a few times before and got great performance. I'm not sure what could possibly be different this time. vblade-19 on the target side AoE v72 kernel module on the initiator. Using mtu 9000 on all of the interfaces involved. HP ProCurve 2810 switch with a dedicated VLAN for the AoE SAN. The switch is set up for 9000 MTU also. The initiator says: aoe: e0.0: setting 8704 byte data frames aoe: e1.0: setting 8704 byte data frames so I know it is getting the MTU right on that side. The initiator has a vlan interface for the SAN which then goes over the bonded link. cat /dev/etherd/err on the initiator produces lots of: unexpected rsp e2.0 tag=7e426...@102e56f91 s=0024e860c18a d=00219b916485 retransmit e2.0 oldtag=00736...@102e56faa newtag=00826faa s=00219b916485 d=0024e860c18a nout=1 unexpected rsp e2.0 tag=00736...@102e56fad s=0024e860c18a d=00219b916485 retransmit e2.0 oldtag=083b7...@102e5700e newtag=083c700e s=00219b916485 d=0024e860c18a nout=1 unexpected rsp e2.0 tag=083b7...@102e57016 s=0024e860c18a d=00219b916485 retransmit e2.0 oldtag=123d7...@102e5708b newtag=1245708b s=00219b916485 d=0024e860c18a nout=1 unexpected rsp e2.0 tag=123d7...@102e57095 s=0024e860c18a d=00219b916485 retransmit e2.0 oldtag=17387...@102e570d6 newtag=174170d6 s=00219b916485 d=0024e860c18a nout=1 unexpected rsp e2.0 tag=17387...@102e570dc s=0024e860c18a d=00219b916485 retransmit e2.0 oldtag=20c87...@102e57153 newtag=20cf7153 s=00219b916485 d=0024e860c18a nout=1 unexpected rsp e2.0 tag=20c87...@102e5715b s=0024e860c18a d=00219b916485 retransmit e2.0 oldtag=2aae7...@102e571d0 newtag=2ab471d0 s=00219b916485 d=0024e860c18a nout=1 At this point I'm at a loss for what the problem could be. -- Tracy Reed http://tracyreed.org
