Hi, Mitch I think you can config ftrace to just trace function calls of btrfs.ko which will save a lot of trace buffer space. See below command: #echo ':mod:btrfs' > /sys/kernel/debug/tracing/set_ftrace_filterAnd please send out the full ftrace log again. Another helpful information might be the strace log of the wmldbcreate process. It will show us the io pattern of this command. Thanks a lot for your help! -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
