Live USB has kernel 4.5.7. Maybe I should try to run "btrfs rescue zero-log" and then mount RW? Will the files safe in that case? > Anyway, even 5 seconds of rm -rf damages too much.

Certainly, I'll make an rsync diff between two-week-ago snapshot and the current FS state. But it will better if in-place recover without backup is possible. P.S. IMHO, log replay by default is a quite dangerous thing. I didn't know about that change and I could lose all files if the live USB had 4.6 kernel)) -- Ivan Sizov (SIvan) -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
