Ah, damn! I found the issue. On the storage server, the storage2 IP
address was wrong, I inversed two digits in the /etc/hosts file,
sorry for that :(
I was able to add the brick now, I started the heal, but still no
data transfer visible.
@Ravi/Pranith - can you help here?
By doing gluster volume status, I have
Status of volume: storage
Gluster process TCP Port RDMA Port Online Pid
------------------------------------------------------------------------------
Brick storage2:/data/data-cluster 49152 0 Y 23101
Brick storage:/data/data-cluster 49152 0 Y 30773
Self-heal Daemon on localhost N/A N/A Y 30050
Self-heal Daemon on storage N/A N/A Y 30792
Any idea?
On storage I have:
Number of Peers: 1
Hostname: 195.65.194.217
Uuid: 7c988af2-9f76-4843-8e6f-d94866d57bb0

Can you resend the attachment as zip? I am unable to extract the
content? We shouldn't have 0 info file. What does gluster peer
status
output say?

0-management:
The last log entry indicates that we hit the
code path in
gd_addbr_validate_replica_count ()
if (replica_count ==
volinfo->replica_count) {
if (!(total_bricks %
volinfo->dist_leaf_count)) {
ret = 1;
goto out;
}
}
It seems unlikely that this snippet was hit because
we print
the E
[MSGID: 106291] in the above message only if ret==-1.
gd_addbr_validate_replica_count() returns -1 and yet not
populates
err_str only when in volinfo->type doesn't match any
of the
known
volume types, so volinfo->type is corrupted perhaps?
You are right, I missed that ret is set to 1 here in the
above
snippet.
@Milos - Can you please provide us the volume info file from
/var/lib/glusterd/vols/<volname>/ from all the three
nodes to
continue
the analysis?
-Ravi
@Pranith, Ravi - Milos was trying to convert a
dist (1 X 1)
volume to a replicate (1 X 2) using add brick
and hit
this issue
where add-brick failed. The cluster is operating
with 3.7.6.
Could you help on what scenario this code path
can be
hit? One
straight forward issue I see here is missing
err_str in
this path.
