Unmounting file systems
/dev/mapper/vgsystem-lvvar has been unmounted
locking_dir = "/var/run/lvm/lock"to e.g.
locking_dir = "/root/lvm/lock"
In case the system requires LVM support during boot up, please run mkinitrd to update the lvm.conf file in the systems initrd file.
Please note: The new changes will only become active when the initrd gets loaded the next time. Hence it is excepted for the system to hang another time before the shutdown.
The LVM locking directory uses /var by default. But in a setup utilizing several separate volumes it needs to be changed to a location on the root volume as this is the last unmounted device.
-the ROOT volume is activated through /lib/mkinitrd/boot/61-lvm2.sh in inirtd
The initrd is made by `mkinitrd` command. `lvdisplay -c` will check if there is block of LVM devices and then decides whether to include LVM module during `mkinitrd`
- NON-ROOT volumes get activated through /lib/udev/rules.d/64-lvm2.rules udev event ->
To check whether lvm support in the initrd is required, please run
to see whether /etc/lvm/lvm.conf has been included. If this is the case, each change to /etc/lvm/lvm.conf requires mkinitrd to be run.
