I read about rollback to earlier state of filesystem when a device 
supporting snapshots (LVM or filesystem) was mounted using FS UUID 
instead of volume identifier. Snapshots have the same UUID as the real 
device, so it is undefined what is found firs on boot. Just ignore this 
remark if snapshots are not supported on all stack levels of your 
storage for the DB.
