Sad, I now want to rip out my LVM setup and go back to straight-up ext3.

I've had some random unexplained file corruption at power-loss, even with safety-first
features of ext3 enabled. I wonder ext3 on LVM would explain it.

LVM without snapshots only uses the linear target.

Eleven years later... is this fixed? Or does LVM still preclude use of barriers?
