If so, one should probably give them a notice.
That was disabled temporarily because changing the fs UUID meant that every piece of checksummed metadata with an embedded UUID would then mismatch. It was fixed (re-allowed) with ce748ea xfs: create new metadata UUID field and incompat flag in the kernel and 9c4e12f xfsprogs: Add new sb_meta_uuid field, update userspace tools to manipulate it in xfsprogs. -Eric -- 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
