It just occurred to me that the system
in question is a development box that
is abused in stress testing and other
scenarios. It crashes in horrible ways
fairly often.
So I realize I should soften my criticism of
LVM mirroring somewhat. Probably the
differences resulted during one of the
numerous kernel deaths. Block-by-block
mirror re-synchronization has been
suppressed by the existence of persistent
mlogs. Then again, I suppose the mirror
log logic is where the failure resides.
That fact and that LVM mirroring
reliably hangs the kernel if a swap
mirror and only moderate system stress
are present leaves me with the conviction
that LVM mirrors will be entirely avoided
here going forward.
