If you turn of the write-cache of the underlying disks, btrfs should survive it. I have btrfs on top of dm-crypt and no write-cache, and it has survived all crashes so far. But you never know, so I backupp regularly. Fsck is not ready yet.

Why not use LVM? If you do not have a partition table (or only one partition) you can only have one file system on the disk, so why not use the entire disk in the first place? // Maria > Thank You for all suggestions and answers. -- 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
