Description Kotresh HR 2019-11-18 11:23:22 UTC
This bug was initially created as a copy of Bug #1761932

I am copying this bug because: 

Description of problem:
with ctime feature, ctime/mtime/atime must be consistent on a file create.

However the ctime is slightly different from mtime/atime

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

How reproducible:

Steps to Reproduce:
1.create 1x3 volume , enable features.ctime, mount volume
2. touch a file say "f1"
3. do a stat of "f1"

[root@dhcp47-105 atime]# stat ctime
  File: ‘ctime’
  Size: 0         	Blocks: 0          IO Block: 131072 regular empty file

Change: 2019-10-15 21:27:49.740912036 +0530 -----> ctime different from a/mtime
 Birth: -

Addition info:
While, I don't see any implication of the above, however this was to be fixed with ctime feature. 
Don't know if there could be any implication or race conditions or a minute window of causing unexpected issues.
