======================This is the IOzone test bug (can be reliably
reproduced)==================================
Btrfs falls into hang when I ran iozone test with the following configuration:
./iozone -s 8g -i 0 -i 2 -i 1 -t 4 -r 4k -+w 50 -+y 20 -+C 60 -F
/mnt/btrfs/test1 /mnt/btrfs/test2 /mnt/btrfs/test3 /mnt/btrfs/test
The bug can be very easily triggered when running this test in my PC.
My PC equipped with 4-core intel I5 cpu, 8G memory and a SSD. dmesg
result is as below, hoping to help you guys:
Oh goody one I can answer! That is fixed by this
Btrfs: fix deadlock with nested trans handles
I'll look into the postmark thing. Thanks,
Josef
