Subject: [PATCH] lvm/mdraid: Fix LVM on MD activation
|
|
|
18971c |
|
|
|
18971c |
The 69-dm-lvm-metad.rules set some udev env. variables that makes it
|
|
|
18971c |
possible to detect the right time to activate LVM on MD. The MD is very
|
|
|
18971c |
similar to DM during activation - it's usable only after proper device
|
|
|
18971c |
activation - the CHANGE event. We need to make a difference between a
|
|
|
18971c |
CHANGE event that comes from this activation and CHANGE event that is
|
|
|
18971c |
the outcome of the WATCH udev rule (otherwise we'd end up with LVM
|
|
|
18971c |
activation done on each CHANGE event - which is wrong).
|
|
|
18971c |
|
|
|
18971c |
So we need the udev databse to be persistent during pivot to root fs
|
|
|
18971c |
even for MD devices.
