Subject: [linux-lvm] LVM performance vs direct dm-thin
Date: Sat, 29 Jan 2022 15:34:06 -0500	[thread overview]
Message-ID: <YfWkwtOTFYxDyYrW@itl-email> (raw)

How much slower are operations on an LVM2 thin pool compared to manually
managing a dm-thin target via ioctls?  I am mostly concerned about
volume snapshot, creation, and destruction.  Data integrity is very
important, so taking shortcuts that risk data loss is out of the
question.  However, the application may have some additional information
that LVM2 does not have.  For instance, it may know that the volume that
it is snapshotting is not in use, or that a certain volume it is
creating will never be used after power-off.
