Yes, the on-disk format changes (and the feature property changes to `active`) when `zpool remove` is used to remove a top-level device (which is only allowed if the feature flag is `enabled`) > can the feature be shipped also separate as a zdb feature for an exported > pool, without needing to upgrade the pool, so a production non-patched pool > can benefit the feature without having to touch the production zfs code and > existing pool on-disk format? No, software that doesn't understand device removal has no hope of ever reading a pool with removed devices. This applies regardless of whether you were to use zdb, zhack, or the kernel to change the on-disk format. -- You are receiving this because you are subscribed to this thread.
