I'm aware of the usual problem of having / as a ccd: the bootblocks won't be able to read the partition, etc... But I remember, on one setup using _mirroring_ (and only in that case of course) where one of the disks died, I just rebooted single user on the remaining disk, changed the ccdconfig line to remove the defective disk, and ran ccdconfig with the same options -- and I was up and running again, with a 1-sided mirror :-) My question is: is there no workaround/unspeakable hack that could be made, with CCD in the kernel, for the bootblocks to read from the first of an N-part mirror, just to get past the boot ? Yeah, I could of course have / = 2 MB and symlink everything somewhere else :-P -- -[ Philippe Regnauld / Sysadmin ]- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
