[Pkg-zfsonlinux-devel] ZFS not booting when on LVM

[John Goerzen]

Hi folks,

I found that when ZFS root is on LVM, it won't boot because it doesn't 
know about it.

The fix could be to copy this section :

activate_vg()
{
         # Sanity checks
         if [ ! -x /sbin/lvm ]; then
                 message "cryptsetup: lvm is not available"
                 return 1
         fi

         # Detect and activate available volume groups
         /sbin/lvm vgscan
         /sbin/lvm vgchange -a y --sysinit
         return $?
}

from /usr/share/initramfs-tools/scripts/local-top/cryptroot.  the 
local-top lvm2 doesn't seem to fire off here for some reason.

My own workaround was to temporarily copy that section into a new file 
in /usr/share/initramfs-tools/scripts/local-top that could do this for 
me on boot (so that it wouldn't be overwritten).  This seems to have 
fixed it.

Thanks,

John
