If you have some room that is unused on your FreeBSD disk slice, you can just use disklabel to make sure it is identified as swap and then put it in /etc/fstab to be used as swap. If you are dual-booted, you could shrink that unworthy MS portion of the disk with something like Partition Magic and make another slice of the newly freed-up space and then use fdisk to make it into a FreeBSD slice (not bootable) and then disklabel to create a partition in it dedicated to swap. Then add it to /etc/fstab. You could add a disk to the machine and use some of it as swap. Make a FreeBSD slice on it with fdisk and then use disklabel to make partitions with one of them (normally 'b') designated swap and then put it in /etc/fstab. If neither of those can happen, then you will need to repartition your existing drive. Although it may be possible to use one of the available utilities to shrink existing partitions within a slice, I would suggest makeing backups of each partition using dump(8) to some media you can preserve. Then reslice/repartition the drive, boot from a rescue disk and restore(8) the dumps. Then in single user mode, fix up /etc/fstab and it should work. Of course, if you are a few versions behind 4.7, then this would be a good time to just do an new install of 4.7 and merge over only the stuff you need to keep from those backups. ////jerry > > - John Mills > > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
