Hi, I hope somebody can guide me as to where I have gone wrong. I have an Intel system with FreeBSD 5.3 installed. I have 1 system disk and 8 other drives connected to 2 Promice IDE controllers. The system disk is un-mirrored. The non-system disk are labled ad4 thru ad11. ad4 thru ad7 on controller 1 and ad8 thru ad11 on contoller 2. I have mirrored between controllers ad4 mirroed with ad8 ad5 '' ad9 ad6 '' ad10 ad7 '' ad11 I was having lots and lots of stability problems from the disk subsystems and was advised in an answer to a previous question to go to 5.4, so... I downloded the CD ISO images of FreeBSD 5. I did a completly new install of 5.4 on the system disk. When I ran the "gmirror load" to my shock and delight all the geom drives were recognised and made available. after a little time resyncing the mirrors all was working fine. Yahoooo. The document I used to set up the GEOM stuff can be found at http://people.freebsd.org/~rse/mirror/ I used the second set of instructions, obviously I did not do it on the system partions but pretty much massaged it to what I wanted to do on all my other disks. So like a prat that can't leave well alone I decided to set up a local copy of the source and rebuild the world and the kernel. This was done, and all appeard to work fine. Builds completed with out errors and the installed happend. I did a mergemaster and at this point I blated a locally edited copy of /boot/loader.conf and removed the 'geom_mirror_load="YES"' directive, I didn't notice at the time, and went ahead and did the reboot. The system started, but failed to complete when it came to the fsck of the disk as mentioned in /etc/fstab. Looked around and found that I had lost the directive from the loader.conf as detailed in the document mentiond above, so put it back in and went for a reboot. This time the system booted and the geom drives were all attached and the system then did it's 15 second wait for the SCSI stuff to settle, then disaster. The system complained with the follwoing message Mounting root from ufs:/dev/da0s1a setrootbyname failed ffs_mountroot: can't find rootvp Root mount failed: 6 Manual root filesystem specification: <fstype>:<device> Mount <device> using filesystem <fstype> eg. ufs:/dev/da0s1a ? List valid disk boot devices <empty line> Abort manual input mountroot> but any thing I type results in a error and the "Manual root filesystem specification" being reprinted. Now I can take the "geom_mirror_load" load directive out of the the loader.conf and the have the boot fail as it cannot fsck the geom disk and then I cna do a manual load of the geom_mirror, fsck the disk and do a control-D to finish the boot. This is fine but a little messy and not very automatic in the event of a system boot. Can anyone sudjest a suitable work rounf that it more automatic or a way to fix the problem permenantly. I was thinking of creating a single disk geom'ed root disk, but I cannot find an incantation to mirror the root disk partitons while preserving the data on them. Any assistance would be most apreciated. Regards David Dooley
