Description Prasad Desala 2017-04-27 11:24:02 UTC 
Description of problem:
=======================
Seeing error "Failed to get the total number of files. Unable to estimate time to complete rebalance" in rebalance logs

Version-Release number of selected component (if applicable):
3.8.4-24.el7rhgs.x86_64

How reproducible:
1/1

Steps to Reproduce:
===================
1) Create a distributed-replicate volume and start it.
2) FUSE mount on a client.
3) Add few bricks and start rebalance. (This error is seen during remove-brick as well)

Note: This error says it is unable to estimate the time to complete rebalance but we are able to see the rebalance estimate time during add-brick or remove-brick rebalance.

Actual results:
===============
Seeing error "Failed to get the total number of files. Unable to estimate time to complete rebalance" in rebalance logs

Expected results:
=================
We should not see error "Failed to get the total number of files. Unable to estimate time to complete rebalance" in rebalance logs.
Comment 3 Nithya Balachandran 2017-05-03 03:49:08 UTC 
This is a bug:


In dht-rebalance.c:


ret = gf_defrag_total_file_cnt (this, &loc);                    
if (!ret) {                                                     
        gf_msg (this->name, GF_LOG_ERROR, 0, 0, "Failed to get "
                "the total number of files. Unable to estimate "
                "time to complete rebalance.");                 
}   

This should be 

if (ret) {
 ...

}
