I've just been playing around with my hard disk partitions (resized the primary DOS partition on my first hard drive using partition magic and changed the cluster size), which is the only thing I can think of that was actually changed in the meantime. I added another FreeBSD partition on a second drive and moved around some directories, but I can't think how that could have caused the problem below: The FreeBSD swap space on my first hard drive seems to be corrupt: this is what disklabel -r /wd0s2a makes of it: [morden] 11:55 ~ disklabel -r /dev/wd0s2a # /dev/wd0s2a: type: ESDI disk: wd0s2 label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 64 sectors/cylinder: 4032 cylinders: 354 sectors/unit: 1427328 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 65536 0 4.2BSD 0 0 0 # (Cyl. 0 - 16*) b: 88256 65536 swap # (Cyl. 16*- 38*) c: 1427328 0 unused 0 0 # (Cyl. 0 - 353) e: 61440 153792 4.2BSD 0 0 0 # (Cyl. 38*- 53*) f: 1212096 215232 4.2BSD 0 0 0 # (Cyl. 53*- 353*) [morden] 11:57 ~ disklabel -r /dev/wd0s2b Bad pack magic number (label is damaged, or pack is unlabeled) By contrast, disklabel -r on my other swap partition on the second hard drive correctly gives me the disklabel summary for the drive. By rights, I should have 88M total swap with these two partitions, but top was reporting it as 133M total. Presumably as a consequence, my processes kept on dying with signal 10 and 11 (I'm assuming this is what hapened when they tried to enter the phantom swap-space). I've removed the first swapon entry from fstab and it seems to be working fine so far. My questions are these: a) How did this happen? b) What can I do to fix it?
