Hi,
I just started some btrfs stress testing on latest linux kernel 3.19-rc4:
A few hours later, filesystem stopped working - the kernel bug report
can be found below.
The test consists of one massive IO thread (writing 100GB files with dd),
and 2 tar instances extracting kernel sources and deleting them afterwards
(I can provide the simple bash script doing this, if needed).
System information (Ubuntu 14.04.1, latest kernel):

Tests are done on 14 SCSI disks, using raid6 for data and metadata:

Maybe this helps to locate the error. If I can do more tests, or
provide more necessary information to diagnose this, please let me
know.

Hi,
your "kernel BUG at fs/btrfs/inode.c:3142!" from 3.19-rc4 corresponds to
http://marc.info/?l=linux-btrfs&m=141903172106342&w=2 - it was "kernel
BUG at /home/apw/COD/linux/fs/btrfs/inode.c:3123!" in 3.18.1, and is
exactly the same code in both cases:
/* grab metadata reservation from transaction handle */
if (reserve) {
ret = btrfs_orphan_reserve_metadata(trans, inode);
BUG_ON(ret); /* -ENOSPC in reservation; Logic error? JDM
*/
}

Year, it's the same.
BTW, I've tried to reproduce this problem by using the way
you told me. However, it hasn't reproduced yet.

Could you give me this script?
