the default mkfs.xfs osd with -i size 2048
xfs=[ # xfs insists on not overwriting previous fs; even if we wipe # partition table, we often recreate it exactly the same way, # so we'll see ghosts of filesystems past
'-f',
'-i', 'size=2048,
],
)

and the just run to write too many data

rados -p rbd bench -b 100K 600000000 write --no-cleanup

and the osd not full and can not write data, so when data is abount 100K ,the inode size 2048 is big? the isize 256 will not has this problem

and i recode it in my blog in chinese:
