Version-Release number of selected component (if applicable):glusterfs-3.4.0.45geo-1


How reproducible:Didn't try to reproduce, but it can be reproduced easily with steps given below


Steps to Reproduce:
1.create and start a geo-rep relationship between master and slave
2. run following command on master mount point, 
./crefi.py -n 100 --multi -b 10 -d 10 --random --max=2K --min=1K -t tar /mnt/master/test/
3.wait for it to complete

Actual results: the status detail shows negative values for files synced 


Expected results: It shouldn't show negative values in status detail. It is disastrous.

Comment 3 Aravinda VK 2015-08-06 14:31:08 UTC

files synced column is removed from status output in RHGS 3.1. If we introduce percistent store while working on RFE 988857, we can show number of Files synced. But with the existing limitation, this column is removed since it will mislead the user. Closing this bug for the same reason. Please reopen this bug if the issue is found again.
