Subject: [PATCH] Do not call 'lvm' for non-LVM device-mapper devices
|
||
|
|
|
||
|
|
If a device-mapper device is not created by LVM it's pointless
|
||
|
|
to call any 'lvm' programs got extract details; they'll be
|
||
|
|
failing anyway. So check the UUID before calling 'lvm'.
|
||
|
|
This speeds up initrd creation and avoids I/O errors on
|
||
|
|
multipath devices.
