i've got a cwfs based on an old fs(4). it gets used infrequently; about a month and a haf ago it sufferend a power outage and i just left it off, since i'd not touched it for a few weeks before that.
today i brought the thing back up, and the active fs is unhappy. on boot, it reports it can't read /adm/users, which makes mounts fail. running newuser complains about /adm/users but adds the user to the table in memor, so i can mount, just to get "phase error -- cannot happen" on any file access attempt. accessing the dump file system works just fine. i'm entirely happy to replace the file system with the last dump. i think "recover" from the configuration mode is the way to do this, but i can't find a description of it and it's been years since i had to do it. in particular, how do i determine the superblock of the last dump? also, this seems like the right oportunity to start using cwfs's -c. any notes on the performance differences?
