Is it safe to mount an LVM2 snapshot of an ext4 fs that has an external journal? My googling has revealed only that the snapshot procedure will cause the fs to checkpoint the journal (if that's the right term) but also that the fs will want to replay the journal when mounted, even if -o ro. If my journal is on an external device (NVRAM device in my case) I don't want the snapshot instance to interfere with the main on-line fs's use of the journal. Is there any documentation, other than code, that describes this scenario? If there is another, more appropriate, venue for my question please let me know.
