Four needed things: - kernel version - btrfs-progs version - complete dmesg for the failed mount - complete btrfs check output (you mostly have this but since the version isn't included, it's not clear this is the entire output) The last two can be included as attachments in a bugzilla.kernel.org bug report and the URL posted in this thread. Typically MUA wrapping nerfs the dmesg making it hard to read, so attachments to a bug report are better. Bugs get reported both in bugzilla and on the list. https://btrfs.wiki.kernel.org/index.php/Problem_FAQ#How_do_I_report_bugs_and_issues.3F Sometimes it takes a while for devs to respond, they also get worked on even without responses just because there's so many improvements each release. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
