My apologies but what sciurus might be addressing and what I am talking about are addressing two very different things. There is a bug in ext4, https://lkml.org/lkml/2012/10/25/521 https://lkml.org/lkml/2012/10/25/521 Note that this is dated after the "Wed, 24 Oct 2012 17:31:29 -0400" post and talks about changing code related to a truncated journal. My post does not say anything about the likelihood of the dataloss due to such bugs, I mention what happens in every design in a WAL journaling system. Talking about the impact of a particular ext bug is up to the people who post on the LKML. To be honest, I don't really care how severe the bug is, I care about why there are bugs and journal truncation is a source of them.
