Then ran "hpacucli ctrl sl=0 ld=1 modify size=max", rebooted into linux (small partition on the server) to use the fdisk there, rebooted back into FreeBSD, it saw the larger drive, larger partition. Then I edited "disklabel -e /dev/da0s4" to edit slice c: and f:. Ran growfs, fsck. and voila I had more space for my logs. -- Regards, Ulf. --------------------------------------------------------------------- Ulf Zimmermann, 1525 Pacific Ave., Alameda, CA-94501, #: 510-865-0204 You can find my resume at: http://www.Alameda.net/~ulf/resume.html
