--- Comment #2 from Nithya Balachandran <nbalacha at redhat.com> ---
xattr information for the volume brick roots were sent by Amudhan over email:

For DTS :


./hashcompute DTS
Name = DTS, hash = 3885892214, (hex = 0xe79e0276)

Looking at the xattrs set on the brick root on the newly added nodes, the
subvol whose range this falls into is qubevaultdr-disperse-97:

>From  qubevaultdrdn021:

qubevaultdrdn021

# file: media/disk26/brick26/
trusted.ec.version=0x00000000000000010000000000000020

trusted.glusterfs.volume-id=0x2b575b5cdf2e449cabb9c56cec27e609


As DTS does exist on this subvolume so readdirp never returned it. As this is
the hashed subvolume, this entry will not be listed until DTS is created on
this subvol by a directory heal operation.


This happens because the fix-layout is performed in a depth first manner. In a
volume with a very large number of directories, it can take a considerable
amount of time for some directories to be healed and hence be visible.
