Alrighty!! Finally got my server rebuilt. I was running out of drive space on several of my partitions (thanks to a horribly underinformed initial install of RedHat 7.2 oh-so-long ago), and I couldn't get PartitionMagic to work on the linux box. Looks like it might have a problem with ext3 partitions. Oh well. After six straight hours of work, I've backed up the system, scrapped all the partitions, and reinstalled Linux from scratch. Now everything looks to be working (fingers crossed), so I'm a happy camper, off to bed with me!!
