--- Comment #5 from Ravishankar N <ravishankar at redhat.com> ---
Changing the component to replicate as it occurs on distribute replicate also.
(Karan, feel free to correct me if I am wrong). Also assigning it to Pranith as
he said he'd work on the fix:

Relevant technical discussions on IRC:
<itisravi>        pranithk1: are you free to talk about the bug Karan raised?
<itisravi>        its a day one issue IMO and not specific to afr.
<itisravi>        s/afr/arbiter   
<pranithk1>       itisravi: He said the bug is not recreatable in 3-way
replication?
<itisravi>        pranithk1: It is..I've requested him to check again.
<itisravi>        pranithk1: so if mkdir fails on one replica subvol due to
quorum not met etc , dht has no roll back
<itisravi>        thats the issue.
<pranithk1>       itisravi: Does it happen on plain replicate?
<itisravi>        pranithk1: no   
<itisravi>        pranithk1: its dht renamedir thing..
<pranithk1>       itisravi: okay, assign the bug to DHT giving the reason
<itisravi>        pranithk1: nithya was saying  if afr_inodelk can also have
quorum checks, then renamedir will not happen
<itisravi>        so we will be good.
<itisravi>        instead of partially creating it on the up subvols of DHT 
<pranithk1>       itisravi: That is not a bad idea, send out a patch. Please
tell her it only prevents the odds, won't fix the problem completely
<itisravi>        pranithk1: we can do it for afr_entrylk also then no?
<pranithk1>       itisravi: Actually the inodelk/finodelk needs to be reworked.
I will send the patch
<pranithk1>       itisravi: yeah, that too
<itisravi>        pranithk1: I see , okay.
