Just make sure you leave a few unallocated blocks at the end of the disk (for gmirror metadata). In most cases, this happens automatically, because the size of the disk is not a multiple of the (fake) cylinder size. To pick one at random, I have a Maxtor 6B300S0 here with 586112591 LBA sectors where the fake c/h/s geometry only adds up to 586111680 sectors, leaving 911 sectors at the end. > We don't want to mirror the whole drive, just the OS partitions.

Mirroring the entire slice is far simpler. If you mirror individual partitions, you have to label them *before* you newfs them. I would mirror the whole drive, though - and I would use ZFS, with which you can easily transition to larger drives (just replace them one by one and resilver in between - you can even do it online if your disks are hot-swappable) DES -- Dag-Erling Smørgrav - [EMAIL PROTECTED] _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
