The feature can be enabled on the pool, but as soon as you use it on any dataset the feature goes from "enabled" to "active" and the boot loader will not be able to read the pool, even if you switch encryption back off. At least that's how it was when the ZoF page was written, if it's different now someone may correct me. > As a follow-up, if it is not currently not possible, are there any > long/short term plans to add the missing bits to our boot loader?ยต > >> The change should be transparent unless you want to use new features. >> I caution against 'zpool upgrade' for the next few weeks. >> >> https://svnweb.freebsd.org/base?view=revision&revision=364746 >> >> If you encounter problems please report them to me, Ryan Moeller, and - >> current. >> _______________________________________________ >> freebsd-fs@freebsd.org mailing list >> https://lists.freebsd.org/mailman/listinfo/freebsd-fs >> To unsubscribe, send any mail to "freebsd-fs-unsubscribe@freebsd.org" > _______________________________________________ > freebsd-current@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
