Something like: lvm pvscan # look to see if the PVs are there. lvm vgscan # is the volume group detected? lvm lvscan # are all of the volumes found OK? lvm vgchange -ay # activate all VGs -- Ray Morris support@bettercgi.com Strongbox - The next generation in site security: http://www.bettercgi.com/strongbox/ Throttlebox - Intelligent Bandwidth Control http://www.bettercgi.com/throttlebox/ Strongbox / Throttlebox affiliate program: http://www.bettercgi.com/affiliates/user/register.php On 05/12/2010 07:21:21 AM, ouyangmaochun wrote: > > My root filesystem is formated as ext3 which is a logical volume > ,and it can not nomally start today,how can I fix this problem.
