Comment 2 for bug 1190779

The details of XFS filesystem where this happened (for those reproducing this):

xfs_info /dev/sda7
==========================

meta-data=/dev/sda7 isize=256 agcount=4, agsize=1387072 blks
         = sectsz=512 attr=2
data = bsize=4096 blocks=5548288, imaxpct=25
         = sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=2709, version=2
         = sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0

Pretty much standard settings.
