Hey all,
I am sort of at a loss at the moment, and I was hoping that someone might be able to shed some light on things. I am new to the concept of AOE, so please bear with me.

# uname -a
Linux springfield.umtri.private 2.6.26-2-sparc64-smp #1 SMP Tue Jan 12 23:43:53 UTC 2010 sparc64 GNU/Linux

So here is the setup 
I have a SunFire 280R connected to two SCSI StorEdge a1000's. The two a1000's are bundled together with LVM, and I created a 5 GB partition (ext3) on them to test with. I "export" that partition using the following.

# vbladed 0 0 eth0 /dev/virt-vol/dom0

which works fine, my client (CentOS 5.4) is able to see the partition and mount it. However when I try to write to e0.0 from the client I get the following in my server logs:

Feb 18 09:44:32 vmdisk kernel: [ 3072.474371] aoe: AoE v74 initialised.               <--- modprobe aoe
Feb 18 09:45:56 vmdisk vbladed: pid 8275: e0.0, 10485760 sectors O_RDWR    <--- vbladed 0 0....

Some writes to e0.0 do work. but they are rather slow. I tried doing an rsync -av /usr /mnt/e0.0 and it got stuck in the middle somewhere, I killed the rsync and
saw those types of message on the server (strbuf_flush....) continue to  fill up the server log for over an hour.

Any ideas?

Thanks,
Nathaniel
