Subject: [PATCH 323/335] cli: display detailed rebalance info
|
|
|
14f8ab |
|
|
|
14f8ab |
Problem: When one of the node is down in cluster,
|
|
|
14f8ab |
rebalance status is not displaying detailed
|
|
|
14f8ab |
information.
|
|
|
14f8ab |
|
|
|
14f8ab |
Cause: In glusterd_volume_rebalance_use_rsp_dict()
|
|
|
14f8ab |
we are aggregating rsp from all the nodes into a
|
|
|
14f8ab |
dictionary and sending it to cli for printing. While
|
|
|
14f8ab |
assigning a index to keys we are considering all the
|
|
|
14f8ab |
peers instead of considering only the peers which are
|
|
|
14f8ab |
up. Because of which, index is not reaching till 1.
|
|
|
14f8ab |
while parsing the rsp cli unable to find status-1
|
|
|
14f8ab |
key in dictionary and going out without printing
|
|
|
14f8ab |
any information.
|
|
|
14f8ab |
|
|
|
14f8ab |
Solution: The simplest fix for this without much
|
|
|
14f8ab |
code change is to continue to look for other keys
|
|
|
14f8ab |
when status-1 key is not found.
