Originally a seed FS becomes a writeable sprout FS after a device is added to it, however as at 4.6 I don't see this behavior anymore. This, the above feature is quite unique to btrfs, and there are some good future solutions on top it. So please preserve this feature and here is a test case [1] which is to make sure we would. On the point of fixing regression, I am trying, traced until 3.8 looks like it failed beyond that. Will continue after my vacation. Further, while digging this out, found another bug in btrfs_init_new_device() which [2] will fix it. (again [2] is not a fix for the regression). ---- [1] [PATCH] btrfs: failed to create sprout should set back to rdonly [2] [PATCH] fstests: btrfs: test case to make sure seed FS is writable after device add -- 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
