G'day all, This is an inconvenience that I would like to get to the bottom of. I have a PII 233MHz 512 MbRAM running FC6. All is fine until swap reaches about 25% used then the system hangs. It will run for days with the swap at 10-15%. My first thought was to run badblocks to see if that was the problem, since it is an old drive, but couldn't find the swap device with mount. My questions are: what would cause this system to hang when the swap file is used?; where is the swap file?; if in the VG, how do I umount it to run badblocks? Here is some output that may be useful. Thanks.
