[dm-devel] multipathd removing DM devices that don't belong to it

[Artem Danielov]

Hello,
Looking for an advice on whether this is an expected behavior or a bug.
device-mapper-multipath-0.4.9-77.el7.x86_64

When multipathd service starts it will remove any DM devices with multipath target, even if the underlying devices are blacklisted.
We are trying to use dmsetup directly  to implement custom multipath management logic separate from multipathd. But unfortunately if multipathd is present and enabled it removes DM devices with multipath target that we create.

Is this a bug?

Thanks for your help!
