By "cold disk" we mean that the pass-phrase and key-material is not available. A laptop which is only suspended does _not_ meet this criteria. > In the first barrier, the manual said that "metadata" is necessary to >locate the lock-sector, I want to know how we get "metadata". It is generated by gbde init. If you don't specify a location it will be stored in the first sector. >The 'da1s1f' partition exists, but I do not mount it. I first try to test >'da0s1f', but the box info:"gbde: /dev/da0s1f: Device busy". Yes, you want to newfs and mount /dev/da0s1f.bde I think the "-l" is a mistake in the usage, it should be "-L". -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
