FC17rc2 rasp : FIX for startup LVM2 & mdadm

[remsnet]

HI all,

I´m "game" with LVM2 and mdadm on one of my rasp´s with Fc17 remix R2 for rasperry..

First of all , you have to have issue install lvm2 , madm , missing init5 sysv scripts for mdadm
bevor you can play with it.

My reasons for change the default Filesystem layout are simple :
I want /var , /usr /opt and /home on LVM2 as my rasp´s planed to run serval years ( +10 ) ..

Game resulted in LVM2 do not startup at boot time.
LVM access seems ONLY after manualy issued "vgchange -ay" or manualy /lib/systemd/fedora-storage-init

SAD Idea that LVM2 startup got removed !!

Reasons seems MISSING required storange systemd services been unmask ´ed
in the fc17rc2 remix .

Here the FIX command ( depend that you installed all required lvm2, mdadm ., systemd ..):

# systemctl unmask fedora-wait-storage.service fedora-storage-init-late.service fedora-storage-init.service

check it:
# systemctl -t service | grep stor
fedora-s...it-late.service loaded active exited Initialize storage subsystems (RAID, LVM, etc.)
fedora-s...ge-init.service loaded active exited Initialize storage subsystems (RAID, LVM, etc.)
fedora-w...storage.service loaded active exited Wait for storage scan

Hi remsnet,

Great advice! I was looking for this solution.
I had previously fc18 alpha running. In that configuration I had a number of file systems (/home, /tmp, /var and /appl) placed in a LVM. These LVM file systems always got active by itself after a reboot.
Now I am running fc18 rc2. And I am running into the problem that the volume group was not available after a reboot. I had to run "vgchange -ay" before the vg got available.
Now "systemctl unmask fedora-wait-storage.service fedora-storage-init-late.service fedora-storage-init.service" fixed it:

Code: Select all

[root@raspi ~]# ll /dev/mapper/

[root@raspi ~]# systemctl unmask fedora-wait-storage.service fedora-storage-init-late.service fedora-storage-init.service

Why would such a thing as LVM be disabled in a new release?

Thanks a lot!
