Code Issues Proposed changes

fixed the error when mounting a lvm snapshot in which filesystem inconsistencies exist 

when we create a lvm snapshot with mode mysql, as no sync commands will be performed, so probably the filesystem of the lvm snapshot is inconsistant. We need to use mount options ro and norecovery to omit inconsistency errors in filesystem.
