HI All, could this be a valid use case of snapshot. We take snapshot while the original volume is under heavy i/o. while taking several snapshot we had put entry on fstab to be mounted when boot up. we had simulate power failure(switch off directly) then power on again,when trying to mount the snapshot volume and original all have lost its label. Volumes cannot be found. could it be the metadata problem? thanks, francism _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
