The md driver might just be waiting for the I/O to fail or succeed
while the AoE command times out. You can adjust aoe_deadsecs if you
like, so that I/O to an unavailable component is failed more quickly.
There is an aoetools-discuss mailing list at the sourceforge
"aoetools" project. There you can talk to other people doing Linux
Software RAID 1 over AoE targets.
