Hi again, Well, I've found out. The problem was the snapshot had been created while the original volume had the "needs_recovery" flag set. If I destroy the snapshot and recreate it when the original volume doesn't have this flag, then I can mount the snapshot. Now the remaining problem is that, _as soon as_ the original ext3 volume is mounted, it has the "needs_recovery" flag. That means I cannot create a usable snapshot volume without first unmounting the original volume (because otherwise I won't be able to mount the snapshot volume). Is there a way to work around this, so as to make snapshots without taking anything down ? (btw : maybe all this should be put in the documentation ;-)) Regards Antoine. > Furthermore, there is another error message on the console : > > EXT2-fs: lvm(58,1): couldn't mount because of unsupported optional > features (4). > Please note : the original LV the snapshot is taken on has the option > "noatime" set. Could the problems come from this one ? _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
