Hi, I'm confused about the following: What happens with an LVM snapshot during journal recovery of a file system? How does the LVM snapshot stay consistent? Here is an example scenario I worry about. Suppose that an ext3 transaction has been committed on disk to the journal inode and a block is written to the file system volume. The old data block is copied to the snapshot volume and some redirection table is updated. Suppose the system crashes and this transaction is replayed from the journal: how can the LVM determine if the copy has already been done (if it cannot, it runs the risk of copying new data into the snapshot volume)? There is probably a good solution to this and I'd like to know what it is.
