Can't we just disable backups somehow? Andreas, vgscan creates cache copies of the metadata in /etc/lvmtab.d/. So if just vgscan and "vgchange -ay" run in the initrd, there's one copy for every VG in /etc/lvmtab.d/ *and* export LVM_VG_MAX_BACKUPS=no disables automatic backup creation in /etc/lvmconf/. vgchange needs little modification to read the data directly from the devices rather than from the cache files. Should I put that into LVM 1.0.4? ;-) > It's the initrd after > all, so it's not like the backups are useful.
