Well, darn. I think I'm in trouble. And I've only myself to blame. Here's the skinny: Laptop running 9.1Pro, with a / partition that was obviously, in hindsight, too small. I actually got started on trying to fix it before it hit critical, using my Knoppix CD and QTParted, but QTP wouldn't touch any hda partitions except the swap (/ and home are both reiserfs) -- the 'resize' option was greyed out. Then I was going to take it to my local LUG meeting this AM, but I had to work instead... and when I booted up, KDE refused to go past the graphical login screen, complaining about insufficient space on /. I'd quote the exact error message, but now KDE won't even give me that -- when I try to logon, I just get the 'waiting' icon for a moment, then I'm back at the login screen. So I figure, okay, I deserve this for procrastinating. I boot back to Knoppix, run parted on my USB backup drive to create an ext2 filesystem, and start trying to do a plain cp * of everything from my hda2 and hda3 into backup directories on the USB drive... and keep getting "read-only filesystem" errors. Say what? Well, I got past that, kind of, I think, and I've got backup copies of all my files (and from now on, I'm going to to full drive backups more regularly). But before I take the plunge, I thought I'd poll the list. From the looks of it, I'd guess I'm probably going to have to destructively re-part the hd, with a bigger / this time, and then copy everything back. Probably have to reinstall some stuff, too. Chalk it up to one more Linux learning experience. But if anyone knows any obvious pitfalls I should avoid while I'm doing this, I'd appreciate any advice offered.
