OK so on further investigation, I can see that btrfs-debug-tree is failing on: ret = find_and_setup_root(tree_root, fs_info, BTRFS_CSUM_TREE_OBJECTID, csum_root); (line 750 or so) But the same call with extent_root and dev_root as arguments are successful. Would this indicate that some branch on the tree holding the file checksums is what's broken? And if so, is there a way to mount the filesystem as read-only while ignoring the checksum tree altogether? Does this even make sense? -- 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
