The lvols are EXT4, and I see that barrier is enabled by-default. I can
try disabling, but need to investigate a bit.
Also, I believe I may have isolated the problem a bit. I can only cause
this behavior when I access these volumes from an NFS client.
I think this might be put it out of scope of the dm code.
