Description Rahul Hinduja 2014-11-03 04:54:51 UTC

Description of problem:
=======================

For USS we have 1 snapd log per volume and as many snap logs for volume. For example if there are 4 volumes having 256 snaps each and USS is enabled than total number of logs under /var/log/glusterfs for USS would be  1028 logs.

Total logs = (4(snapd per volume) + 4(volumes)*256(snaps)) = 1028

Hence, it makes sense to move into into sub-folder structure like

/var/log/glusterfs/snaps/<vol-name>/<snapd + snaps logs>


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

glusterfs-3.6.0.30-1.el6rhs.x86_64


How reproducible:
=================

always


Steps to Reproduce:
===================
1. Create 4 node cluster 
2. Create 4 volumes
3. Enable USS
4. Create 256 snaps of each volume

Actual results:
===============
Total 1028 log entries are created under /var/log/glusterfs

Expected results:
=================

It is good to separate these logs and put it under some subdirectory like 

/var/log/glusterfs/snaps/<vol-name>/<snapd + snaps logs>
