Subject: [PATCH 2/2] Skip persistent device link creation on multipath device
|
||
|
|
paths
|
||
|
|
|
||
|
|
When a device is marked as a multipath device path by setting
|
||
|
|
DM_MULTIPATH_DEVICE_PATH="1" udev should not create any
|
||
|
|
persistent symlinks to that device.
|
||
|
|
Otherwise systemd will get confused about which device to use.
