Are all Physical Volumes accessible (run pvscan and analyze) ? If any are missing that is likely to explain your problem. It is hard to help you here without knowing what happened to the system :( Of course you can use a metadata backup and restore it but this is no good advice either without knowing which changes have been made (i.e. multiple lvcreate/lvremove/lvextend/lvreduce meanwhile) and which metadata backup should be restored, preusmably _all_ PVs are accessible. You want to read pvcreate and vgcfgrestore manual pages and use the -ll option of vgcfgrestore to analyze your backup contents. > > later, when in was in office i have turn on the server and the vgscan failed, > it said " ..omissis... only found 499 of 500 LE for LV > /dev/volume1/lgv1(0)" . > I don't undestand what was happened. > It is possible that a bad tuned off make a problem as this? > Any body know the answer? > > To solve the trouble i thinked to do in this way: > to reduce the LV lgv1 of some LE , in this way the info about the number of LE > will rewrite and (i hope) the problem vanish.The idea seems good, isn't? > But i can't do this because the volume group is inactive. > Anybody know a method to active a volume group also if vgscan fail? > > Please, i MUST to recove the data on the lv, we don't have a backup policy > >:^> > > > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
