Description Ram Raja 2018-04-23 15:36:37 UTC 
Created attachment 1425684 [details]
ganesha config file

Description of problem:
To disable Ganesha's attribute caching for all exports, you need to set
'Attr_Expiration_Time=0' as a EXPORT_DEFAULTS options. This is not working.
But we need this working for setting up NFS-Ganesha in OpenStack Manila deployments, where we want to turn off attribute caching.

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


How reproducible: Always


Steps to Reproduce:
1. Setup Ganesha over CephFS and use the attached ganesha.conf file.

2. Start the ganesha server.

3. Check out the ganesha log file for warnings or errors.

Actual results: See a warning in the ganesha log file,
[main] config_errs_to_log :CONFIG :WARN :Config File (/etc/ganesha/ganesha.conf:10): Unknown parameter (Attr_Expiration_Time)

Expected results: Shouldn't see the warning in the ganesha in the config file.

Comment 3 Ram Raja 2018-04-23 15:37:57 UTC 
The fix is in upstream nfs-ganesha project's next branch,
https://github.com/nfs-ganesha/nfs-ganesha/commit/e76c786d1f41d14b5bc3e4086136e11e93f04021

Shouldn't be hard to backport and it's easy to test.
