So it's data single *and* metadata single? > btrfs check will lead to "Couldn't open file system" Try btrfs-progs all the most recent btrfs-progs to see if it's any different: 4.5.3, 4.6.1, 4.7 (or 4.7.1 if you can get it, it's days old). > > > [ 98.534830] BTRFS error (device sde): parent transid verify failed on > 22168481054720 wanted 1826943 found 1828546 That's pretty weird. It wants a LOWER generation number than what it found? By quite a bit. It's nearly 1500 generations different. I don't know what can cause this kind of confusion or how to fix it. Maybe take advantage of the fact it does read only and recreate it. You could take a btrfs-image and btrfs-debug-tree first, because there's some bug somewhere: somehow it became inconsistent, and can't be fixed at mount time or even with btrfs check. -- Chris Murphy -- 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
