My setup is an amd k6/2 300 with 160mb ram, a 3 gig IDE drive, and two 34 gig IDE drives. The 3 gig drive is the primary master, with filesystems for /, swap, /usr, /var, /tmp, and /home. The two 34 gig drives each have a single 30 gig filesystem, the two of which are striped RAID-0 with vinum. Softupdates are running on all filesystems except for /. I had repeated problems getting the large IDE drives to work, and I've come to understand that FreeBSD has some bugs with regard to these drives, and my workaround was to use less than their full size and stripe them. They seem to be working fine, but I'm experiencing another problem that's approaching severe. After doing a cvsup and make world last week, I noticed a slew of messages on reboot saying "bad file descriptor: /dev/wd2" etc. There were about 20 of them and they were almost all in the /dev directory and they were all on the / filesystem. I rebooted in single user and ran fsck on the read only root system and restarted, and the number of error messages was reduced to three. I posted a query about it on -questions, but no one answered. Then, after a subsequent cvsup and make world, I rebooted to see 20 something bad file descriptor warnings again. This time, when I brought it down to single user and fsck'd it, one of the files it "corrected" was the system console device, and another was the character mode device for the /usr filesystem, resulting in kernel panics on startup. I attempted to fix it with a "fix it" disk, but apparently I wasn't up to the task. I ended up re-fdisk'ing the drive and doing a complete reinstall of BSD and all the filesystems on the 3 gig primary master drive. Incidentally the 3 gig drive formats with no bad sectors, as do the other two. The BIOS is set to normal mode for all three, and BSD seems to recognize them with the correct geometry. After doing my reinstall of 3.4-RELEASE, I did a quick kernel build to get my internet connection back up and running with ipfw, then cvsup'd and did a make world. When I finished make world, build a new kernel (just adding IPDIVERT, IPFIREWALL, IPFIREWALL_VERBOSE and SOFTUPDATES) and rebooted, a had twenty something bad file descriptor messages, just like before. I'm afraid to reboot the thing or do any more make worlds because I can't afford for this machine to be down any more than it has been. Can someone tell me what's going on? My first reaction was that maybe the FreeBSD bug about IDE drives was the problem, but all of my problems are on the / filesystem on a drive that's only 3 gig in size, a size that's extremely common. I'm really at a loss here, any help you could provide would be greatly appreciated.
