[Jfs-discussion] System hangs: JFS on IDE drives

[Jacob Herbold]

Hello,

I've looked around and can't seem to find a solution to this problem.

I'm upgrading an existing system with additional storage capacity and will be reinstalling linux, however I was checking things out first and ran into this problem.

First off I'm not sure this is a JFS problem at all, but I haven't had probelms with these disks until I tried JFS on them. I hope someone might suggest how I can shine some light on what's going on.

Using redhat 7.0, 2.4.17 kernel with JFS 2.4-1.0.15-patch, used kgcc to compile the kernel with JFS as a module. System is a dual pentium 233 MMX with a Promise 100TX2 ATA-100 (PDC202658 chip) card on the PCI bus. I boot from the IDE drive attached to the 430HX chipset's ATA controller on the motherboard. I'm not using the ATA-100 disks for anything but testing right now.

Here's what happens: when the benchmark, bonnie++, deletes many files from the partition, it hangs and I am unable to kill it. If I am quick I can halt the system and reboot. Otherwise it freezes completely (no echo on consoles) and I'm forced to do a hardware reset.

While I recompiled with JFS debugging on, and changed /etc/syslog.conf to see debug info in the logs I haven't seen
anything. I've run the same test on the disks using ext2 and ext3 partitions and seen no problems. At first I was using software raid 0. However, even without raid, the same test on a JFS formated partition caused the same problem. The only messages I have seen are a waring about an old MD ioctl:
"md: fsck.jfs(pid 1045) used obsolete MD ioctl, upgrade your software to use new ictls."

Please, what can I do to find out where the problem is?

Thanks,

-Jake
