Need vinum info/advice, fast.
A client has hired me to do some work, part of which is replacing Red Hat 9, which is end-of-lifed at the end of this month. I'd convinced him to let me install FreeBSD, right up until I told him that - to my knowledge - you cannot trivially set up software raid on FreeBSD, during install, as you can with Red Hat Linux. I'm supposed to build the new server tomorrow. *Is* there any way I can set up software raid of two ide disks, during install, and for all partitions? This is just to mirror the system disk, so that we can avoid downtime, and going to backups in case of a disk failure. If it can be done, how do I do it? I've never used vinum before, and only know what it is, but nothing about it. I wish I had more than one night to figure this out, but I don't. If it isn't FreeBSD, he going to likely want me to install Fedora Core 2 Linux, instead.

I just read that chapter, and, while it makes some sense, it didn't tell me anything about how to do mirroring during install, or how to mirror an existing drive after installation of the OS. I don't see anything incorrect in it. You may find the description at http://www.vinumvm.org/cfbsd/vinum.pdf easier to understand. Thanks. Will read that now, and then post any questions I have. I appreciate the rapid responses, guys. :) -ste ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/vinum-root.html http://www.vinumvm.org/cfbsd/vinum.pdf Ok. I've read both documents, which were quite educational. Thanks. :) It seems that what I want to do is install to the first system disk, as normally, and then convert that disk to a vinum disk, using the method described starting on page 237 of the above vinum.pdf. The steps aren't entirely clear to me, after that, as to how to make the second disk a vinum drive that is a mirror of the first. Do I just partition it as normally, but saying that the partition types are type vinum? Then do I format those new partitions, and then describe the volume, plexes and subdisks in the configuration file, adding each subdisk to the existing setup so it will mirror? Do I ever even have to format thos partitions, or does vinum just recreate the filesystems bit by bit? I'm not sure I'm asking the right questions. Pointers are most welcome. :) -ste ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
