But we double check our volume,all nodes has the size
it had all 1.5TB.See below the xfs_info of both nodes.
We can only encountered this problem if volume is more than 1TB. ^
But my guts tell me that there is something wrong so
We carry out anothere fs test. We test EXT3
with the same size and everything is the same.
the result is what we expect, its okey..
Is this something to do with compatibility issue of xfs & lvm?

ok. then, your lower level devices on the two nodes are not of the same
size, and you created the file system on the larger one.
now they connect, and DRBD can only "export" the minimum of the device
sizes to user space.
let me quote from the log below:
first creation of state block:
> drbd0: 1536032768 KB now marked out-of-sync by on disk bit-map.
after handshake:
> drbd0: 1535508480 KB now marked out-of-sync by on disk bit-map.
these are 3071016960 sectors, which is later the "limit"
in the "attempt ..." messages.
> drbd0: rw=0, want=3072065536, limit=3071016960
whereas XFS still thinks it has 3072065536 sectors,
and tries to use them.
does that make sense to you?
