I'm using 4.10 on various sytems, and getting the same problems on SCSI, ATA (direct and via a Promise TX2) with ufs or vinum and it's driving me nuts! After installing a base OS disk (no problems there), I add other disks and partitions. Now, to be lazy, I usually cheat by using /stand/sysinstall, first fdisk, then label, no boot manager. Usually, it works 100% and I keep my lazy factor high. As of 4.10, it started to complain about invalid argument when I would create a parition, and attempt to newfs/mount it. So, I got "un"-lazy and attempted to do it manually. I do (using ar0 as the example device): fdisk -I ar0 disklabel -r -w ar0 auto disklabel -e ar0 I muck around in disklabel and make my partitions, expending *far* too much energy as compared to /stand/sysinstall. Save and exit. Then I do the nice newfs. newfs -N -b 16384 -f 2048 -i 32768 -c 102 /dev/ar0s1e It newfs's wonderfully, showing me all the superblock locations and such as I yawn at this unnecessary work. Then I attempt to mount the partition: mount /dev/ar0s1e /mnt And I get: sh1# mount /usr/home mount: /dev/ar0s1e on /usr/home: incorrect super block /var/log/messages shows: dscheck(#ar/0x20002): fixlabel: invalid magic fixlabel: invalid magic WHAT GIVES? I have attempted obliterating the info on disk with a dd to the c partition and the raw device itself. As mentioned, I have this problem with all sorts of devices, so a number of scenarios present themselves: 1. FreeBSD 4.10 disklabel/fdisk has some form of regression 2. I am the one suffering from the regression and being too lazy for too long forget what to do As another note, I attempted the same thing under FreeBSD 4.8 and had no problem!!! Any help would be appreciated. I've tried everything except taking the disks to dinner to get them to take a fileystem! -- Tony Holmes Ph: (416) 993-1219 Founder and Senior Systems Architect Crosswinds Internet Communications Inc.
