[Krutika Dhananjay <kdhananj@xxxxxxxxxx>]

I posted a patch for fixing this problem @ http://review.gluster.org/#/c/9267/

Emmanuel,

Could you apply this patch on NetBSD and see if the test passes now?

Emmanuel/Pranith,

Could you please review this patch?

Hmmm.. thanks for the info, Emmanuel.

I'm waiting on a NetBSD machine for debugging this issue.

I will let you know what I find, when I'm done.

Tracing further:

afr_selfheal_find_direction() get the matrix:
0 1
1 0

As a result, witness[] is all zero, there is no source.

Could it be otherwise? The offending node is obtained this way (I
stripped other operations), I do not see how it could be healed, after
all:

TEST mkdir spb_me_heal

TEST kill_brick $V0 $H0 $B0/${V0}0
TEST touch spb_me_heal/0

$CLI volume stop $V0
$CLI volume start $V0 force
EXPECT_WITHIN $PROCESS_UP_TIMEOUT "1" afr_child_up_status $V0 0
EXPECT_WITHIN $PROCESS_UP_TIMEOUT "1" afr_child_up_status $V0 1
TEST kill_brick $V0 $H0 $B0/${V0}1

TEST touch spb_me_heal/1

$CLI volume stop $V0

$CLI volume start $V0 force
EXPECT_WITHIN $PROCESS_UP_TIMEOUT "1" afr_child_up_status $V0 1
EXPECT_WITHIN $PROCESS_UP_TIMEOUT "1" afr_child_up_status $V0 0
