In Linux, doing this on *any* filesystem will potentially cause corruption.
This is why e2dump/e2restore are *unsafe* and not to be used.
Raw I/O operations bypass the buffer cache, so of course it'd be corrupted.
If you're dicking with device access while a partition is mounted and
you lose data, you deserve what you get. This behavior has been a no-no
forever.
This leads one to believe that using XFS on LVM,
md, or enbd would be somewhat risky.
I dunno what 'enbd' is, but XFS on LVM or md is perfectly safe. They're
kernel drivers for starters, so they can coordinate block I/O
operations. They also sit below XFS in the I/O layer, XFS just sees
them as another partition.
I dunno how you came across this conclusion at all.
