Does a softraid(4) crypto volume require metadata backup? (I am running amd64 OpenBSD 6.9 if it is relevant, will probably upgrade in the next few months.)
I understand FreeBSD GELI (e.g.) requires such a backup to protect against crypto-related metadata corruption rendering the encrypted volume inaccessible. Neither the OpenBSD disk FAQ nor the man pages for softraid(4) or bioctl(8) have anything to say about the matter. Web searches also turn up no relevant information. Thanks, Nathan Carruth
