What I want to know is whether this is such an incredibly bad idea I shouldn't even consider it --or-- it seems like a good way to get familiar with gmirror, so go for it. Besides slowing down your I/O, it shouldn't be a huge deal. I don't know that there's a whole lot to learn about gmirror, but in the interest of furthering debate, I've done more than a little bit of learning in those areas thanks to the joys of qemu. It does have the advantage of not trashing your desktop if you should do something horribly silly, as I would admit to being wont. -- -- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

If you want to do this for the sake of practice, by all means, feel free. However, mirroring onto the same device is going to result in almost no benefit to reliability and will cause a very large performance hit, as well as reducing the usable amount of disk space in half. (In other words, actually leaving the machine set up that way would be an incredibly bad idea.) -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

(In other words, actually leaving the machine set up that way would be an incredibly bad idea.) Mr. Swiger; I agree, except that I had anticipated absolutely *no* benefit to reliability. If the disk goes bad, then having a mirror on the same disk, different slice, would still give me...no disk. I simply wanted to get the practice by actually doing, instead of just reading about it. I'll probably re-install Slackware on the other slice when I get done playing around.
