thx, ed. this is a case where I am wondering whether EVERYONE, including all the commercial contributors to btrfs, would be better off with another additional license that also allowed kernel integration for companies like Apple. the decision-making (and rights) for btrfs are so dispersed, howev

Telling someone (that has a ~2 week stale backup) that they should have kept backups is hardly constructive. We're all aware there's no official btrfs repair tool. But it appears there has been been some hard, dedicated work towards this that has resulted in many commits and patches. I'm here to

"Soon" seems a bit subjective given that the devs have been touting this since the beginning of time. /Helpful/ advice would be nice. This blog posting (http://stujordan.wordpress.com/2011/06/20/churning-the-butter/) sounded promising, but none of the superblock copies on my btrfs volume are ok,

Fajar, Thank you for the suggestion. Unfortunately, running "sudo ./btrfs-zero-log /dev/mapper/home" results in the same "parent transid verify failed on 647363842048 wanted 210333 found 210302" errors, repeated 3 times. I am running Arch Linux with the latest 3.0.1 kernel on a x86_64 machine.

Hello, trying out btrfs on my linux installation. I am running Funtoo with Linux 3.0 kernel. After a reboot kernel panicked (no access to error log since it is my root volume that failed). I get this using a rescue cd (2.6.38, btrfs v 0.19) and then trying to mount : [  752.129118] btrfs bad tree

Not in all cases you can plan and predict where there will be need for deleting large number of files. Also subvolumes are difficult to maintain, not to mention still quite buggy. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.ke
