--- Comment #1 from Ravishankar N <ravishankar at redhat.com> ---
This is expected behaviour. I was not able to re-create the issue only when
when there were pending heals like so:
1. Create arbiter volume and fuse mount it.
2. Kill brick 2.
3. Create files from the mount:
for (( i=1;i<=5000;i++ )) 
do 
dd if=/dev/urandom of=file$i bs=1024 count=1
done
4. Bring down brick 1, then brick up brick 2
5. Trigger index heal, let entry+mdata selfheal complete from b3 to b2.
6. rm -rf * from mount
7. Bring back b1, trigger index heal.

On the brick log of b1:

RCA: This is basically a race between entry heal and data heal. When b1 comes
back up, entry selfheal expunges all files in it. In the mean time, the gfid
indices inside brick1/.glusterfs/indices/xattrop also get processed. If the
entry heal had already expunged the file, the stale index is removed,
Otherwise, it will proceed to self-heal code-path, which tries to lookup, open
(data self-heal) etc, which will fail at various points depending on when the
entry self-heal purges



Closing the BZ as NOTABUG. Karan, if you are able to hit the issue when doing
rm -rf when there are no pending heals, feel free to re-open the BZ.
