Bug ID: 1224076
Summary: [Backup]: Glusterfind not working with change-detector
as 'changelog'
Product: Red Hat Gluster Storage
Version: 3.1
Component: glusterfs
Sub Component: glusterfind
Severity: medium
Assignee: rhs-bugs at redhat.com
Reporter: sanandpa at redhat.com

Depends On: 1208520
Blocks: 1186580 (qe_tracker_everglades)
+++ This bug was initially created as a clone of Bug #1208520 +++
Description of problem:
When the glusterfind pre command is run with change-detector as 'brickfind' it
works fine. When it is run with 'changelog' it errors out saying change
detection failed.
Version-Release number of selected component (if applicable):
Gluster 3.7 upstream nightly glusterfs-3.7dev-0.852.git3feaf16.el6.x86_64
How reproducible: Always
Steps to Reproduce:
1. Have a gluster volume, say 'ozone' and create a glusterfind session
glusterfind create <sessionName> <volumeName>
2. Run the glusterfind pre command with change-detector as 'changelog'
glusterfind pre <sessionName> <volumeName> /tmp/outfile.txt
--change-detector=changelog
Actual results:
Step2 should succeed. The specified output file 'outfile.txt' should get
updated with the list of changed files, from the last change
Expected results:
Step 2 errors out saying: Change detection failed
Additional info:
Could not get much info from the logs as well. It just says: Change detection
failed.

Issue is due to BZ 1207643. We don't need any patch for glusterfind to fix this
apart from patches sent for 1207643
--- Additional comment from Aravinda VK on 2015-04-06 04:21:31 EDT ---
Addition to the patch sent for BZ 1207643, we need to install "pyxattr"
package.
yum install pyxattr
or
pip install pyxattr
--- Additional comment from Sweta Anandpara on 2015-04-06 08:14:25 EDT ---
After installing the pyxattr package, the 'glusterfind pre' command still fails
with the error: Change detection failed.
However, I do see the changelog log files now. This is the error snippet:

The setup is 10.70.43.140 is in the same state, if you would want to have a
look.
