Hey folks, I just upgraded my system from a ~200GB mirror to a ~1TB RAID5, but all has not transitioned well. I really don't know how to debug this issue, though I have tried. I gave up this morning before work, but I was going to try the magickey next (something I don't really know how to use, but anything for a clue) followed by upgrading to 2.4.21. The lock up is typical to a system with a failing drive; the system is responsive to input, but nothing happens. Keyboard works fine, but programs become idle (not really crashing.) I tried keeping "top" up, hoping I would see something obvious, like raid5syncd doing something strange, but if it does, top doesn't update after the problem. The lockups happen even if the system is doing nothing (other than raid5syncd, which is awfully busy since my RAID won't stay up) If I unmount the RAID5 and RAIDSTOP it, my system will work fine, but I'm out 1TB of disk. Right now, I have it running the bare essentials (all services on, but my /home directory has only public_html and mail stuff for each user.) Anything I can do to get more information out of this problem? I don't really know where to look. System Infro ======================================================================= My kernel is 2.4.20, my raid tools is raidtools-0.90, no patches on anything, home built distro (linux from scratch.) Had been running on a mirror for nearly a year. Each drive on my system is connected to promise UltraATA 100 controllers. I have 6 drives and 3 controllers. Each drive is a 200GB WD drive, set to "Single/Master" on their channel. No device has a slave.
