Hi all, I've recently run into an issue with ext4 and delayed allocation where my system will silently hang just seconds into a dbench run. I first saw this using 2.6.30.9, but it still happens with 2.6.32-rc8. I've tried with an SMP x86_64 system, and a UP i386 system. The SMP x86_64 system hangs every time for me within 15 seconds, but the UP i386 system never hangs on me. If I remount with -o nodelalloc on the SMP system, the hang goes away. There are no messages printed out by the kernel; it just locks hard. Has anyone seen this before? I'm just running "dbench 500" to produce this behavior. -Justin -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
