This is interesting at some level, as it is ext3 with snapshots. It is also not as interesting as it is based on … ext3 … which isn’t exactly a high performance file system. Not to mention the 8TB limit on volumes, and 2TB on files. Haven’t seen customers run into the latter, have seen them run into the former. Head first, and hard.
I’d argue that this capability would be better merged with ext4, though as I understand it, Ted T’so isn’t quite interested at this point. Merging this into ext4 could be hard.
