LVM2 (non-root) lv's won't mount at boot time


Hey everyone...

I've got LVM2 set up and working. My only problem is that the volumes will not activate at boot time. I have a 20GB volume named homevol (/dev/vg0/homevol). When I manually do 'lvchange -ay /dev/vg0/homevol' all is well.

I though simply adding the appropriate vgchange and lvchange commands to /etc/rc would activate everything at boot time, but no luck. I will make an initrd if I must, but I don't see why I would have to. Anybody have a similar experience?

Applicable info:
linux 2.6.6
devfs (daemon and kernel protocol rev 5), mounts at boot
lvm 2.00.33

Thanks...

My /etc/fstab, give you any ideas?

[nonzero@blacky ~]$ cat /etc/fstab

Thanks for the reply. My fstab is good. For instance, I have the following entry:

/dev/vg0/homevol /home reiserfs defaults 0 0

If I were to log in after a reboot, however, /home won't be mounted. So,

#mount /home
mount: special device /dev/vg0/homevol does not exist

Wow, that's weird...

#lvdisplay
LV Name /dev/vg0/homevol
VG Name vg0
LV Write Access read/write
LV Status NOT available
...

There's the culprit. homevol's not active.

#lvchange -ay /dev/vg0/homevol
#mount /home

Homes are back.

But when I put the vgchange and lvchange commands in my rc scripts, they just don't seem to do anything. No logs, nothing. I'm running out of ideas. Maybe you could grep -R "\(lv\|vg\)change" /etc/* for me?

Thanks again...
