You may add "r|/dev/dm-.*|" to your lvm filter list.
But this should be equal as your current lvm filter
filter = [ "a|drbd.*|", "a|md.*|", "r|.*|" ]
ignores it already.
But you get /dev/dm-3 as PV for VG vm and dm-3
Hello Roland,
I attached the output to this email.
I noticed that DRBD is started at the end of the boot process but LVM is
obviously started before that.
That means that I have to rescan for volume groups after DRBD has
started, but it still does not explain why I can not use the device

Sorry my fault - /dev/vgsys/test02 was my testing lv.
On your system it should be:

Hello List,
This is more lvm centric, just wandered if anyone could point out what I

I have the following setup:
sda1 => +---+
|md0|
sdb1 => +---+ => lvm:system-drdb => drdb:r0 => lvm:vm
Before the creation of volume group vm:
"/dev/mapper/system-drbd" is a new phy
