Hi! The problem is that the BTRFS raid10 filesystem without any understandable cause refuses to mount.

Hi, I try to format a USB memory with a Btrfs. I can format it with mkfs.btrfs without problems. But; when I try to mount it, it fails to mount with the below error messages. But the USB memory works fine with other filesystems (ext4, XFS etc.). So, the hardware is not faulty. tarkane@tarkane:~$ sudo mkfs.btrfs -d single -n 4096 /dev/sdb1 WARNING! - Btrfs v0.18-26-g0030f1d IS EXPERIMENTAL

I have a couple computers running 2.6.38 (Ubuntu Natty 2.6.38-8-generic), and on both of them "btrfs device scan" comes back with nothing other than "failed to read /dev/sr0" One computer has a btrfs RAID-1 volume, and the other has two separate btrfs filesystems. The results are the same whether the filesystems are mounted or not. Why is "btrfs device scan" not

As far as I know, btrfs comes from "btree file system", but why does btrfs pronounce "butter-eff-ess"? -- Wang Shaoyan -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It is well documented that btrfs data recovery (after silent corruption) is dependent on the use of btrfs''s own RAID1. However, I''m curious about whether any hardware RAID vendors are contemplating ways to integrate more closely with btrfs, for example, such that when btrfs detects a bad checksum, it would be able to ask the hardware RAID controller to return all alternate
