Description Rahul Hinduja 2014-06-16 07:18:45 UTC
Description of problem:
=======================

In a scenario where auto-delete is set to disable and snapshot creation reaches to its snap-max-soft-limit, with subsequent snapshot creation we create a snap and put a warning as follows:

[root@snapshot13 ~]# gluster snapshot create snap27 vol0
snapshot create: success: Snap snap27 created successfully
Warning: Soft-limit of volume (vol0) is reached. Snapshot creation is not possible once hard-limit is reached.
[root@snapshot13 ~]# 

The warning ideally should also be logged into the log messages which is not logging currently

Current log messages, upon reaching the snap-max-soft-limit and subsequent creation:

[2014-06-16 07:05:37.829227] I [rpc-clnt.c:969:rpc_clnt_connection_init] 0-management: setting frame-timeout to 600

Version-Release number of selected component (if applicable):
=============================================================

glusterfs-3.6.0.17-1.el6rhs.x86_64


How reproducible:
=================
1/1


Steps to Reproduce:
===================
1. Set the auto-delete to disable
2. Start creating snapshot until it reaches snap-max-soft-limit
3. Create another snapshot, which is successful and warning should be logged successfully on the console

Actual results:
===============

Snapshot creation is successful and warning is logged on console, but it didn't log any warning in the logs.

Expected results:
=================
Snapshot creation is successful and warning is logged on console, it should also log warning in the logs.
