If the space was already in a slice and you just wanted to expand a partition in to the unused space, then you could use growfs(8), but I don't think that will work to expand a slice. Really, the easiest thing is to use dump(8) to back up the existing 6 GB. It will be necessary to do a dump for each file system (partition) you have in the slice other than swap or /tmp. Then build the 40 GB disk as needed. You can best do this from a fixit CD. You will need to make a slice with fdisk, then divide that slice into partitions with bsdlabel. Then for each partition except for swap, use newfs to build a file system in them. When that is done, make temporary mount points, mount the partitions and restore the dumps. This sounds long and drawn out telling it, but it is actually quite easy and works well. If it is your boot disk, then the fdisk should write the MBR and the bsdlabel needs to write the boot sector for the slice. There is a good example of fdisk and bsddlabel use for creating a brand new bootable disk with one FreeBSD slice in the bsdlabel man page near the bottom. Also, in the last few days I have posted several replies to questions that would cover this process and included extensive examples. The only difference is that they weren't for mirrored disks. But, it sounds like you got rid of the mirror anyway. The dump/rebuild/restore is the way to go even if you do it to a new mirror of the 40GB drives. Or you could write the dumps to one of the rather than tape and restore from that. ////jerry > > > Thank You. > Peter Clark > > _______________________________________________ > email@example.com mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
