Subject: Update instructions for manual LVM start + fix LVM detection for lvm boot option
X-Git-Tag: v0.15.8~1
X-Git-Url: http://git.grml.org/?p=grml-autoconfig.git;a=commitdiff_plain;h=20365ddcfab071d7447b346a6ebf804b56d394b6

Update instructions for manual LVM start + fix LVM detection for lvm boot option

service lvm2-lvmetad doesn't do what we assumed it does.
Instead 'Start lvm2-pvscan@name' allows startup of the
given LV or VG (which is actually nice).

Also we need to explicitely execute `vgchange -a` to
start any present LVs.

Closes grml/grml#31
