There have been lots of fixes between 3.8 and 3.10.

This isn't specific to your question, but in general... In the "Question: How can I recover this partition?

I'd try that. http://permalink.gmane.org/gmane.comp.file-systems.btrfs/27999 (I have it marked to possibly add the info to the wiki as I don't remember seeing such a concise list there, but I haven't gotten around to it yet.)

Unmountable BTRFS with parent transid verify failed
Hi, I have a 9 disk raid1 filesystem that is no longer mountable. I am using ubuntu 13.04 with kernel 3.8.0-26-generic What happened was that I was removing a device using btrfs device delete and this was running for quite a while (I was removing a 3T device) but eventually this failed with the btrfs command segfaulting. Now when I have rebooted but the filesystem does not mount. When I run "btrfsck /dev/sde" I get a lot of parent transid verify failed on 3539986560 wanted 301481 found 301495 parent transid verify failed on 3539986560 wanted 301481 found 301495 parent transid verify failed on 3539986560 wanted 301481 found 301495 parent transid verify failed on 3539986560 wanted 301481 found 301495 Ignoring transid failure leaf parent key incorrect 3539986560 leaf parent key incorrect 3536398464 bad block 3536398464 And while btrfsck eventually does complete the filesystem remains unmountable. Any advice ? regards ronnie sahlberg -- 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
