Comment 7 Manisha Saini 2023-09-20 09:50:45 UTC 
Hi Frank,

Could you let me know the test scenarios that QE should run to verify this fix?
Comment 8 Frank Filz 2023-09-20 16:02:41 UTC 
This change impacts the primary data path, so any I/O workload will exercise these changes.
Comment 9 Manisha Saini 2023-09-25 19:17:27 UTC 
Verified this BZ with

# rpm -qa | grep nfs
libnfsidmap-2.5.4-18.el9.x86_64
nfs-utils-2.5.4-18.el9.x86_64
nfs-ganesha-selinux-5.5-1.el9cp.noarch

nfs-ganesha-rados-grace-5.5-1.el9cp.x86_64
nfs-ganesha-rados-urls-5.5-1.el9cp.x86_64

[ceph: root@argo016 /]# ceph --version
ceph version 18.2.0-43.el9cp (1aeeec9f1ff5ae66acacb620ef975527114c8f6e) reef (stable)

Performed sanity testing with nfs v5.5 build. I/O worklods are getting completed without any failures.Moving this BZ to verified state.
Comment 12 Frank Filz 2023-10-27 23:47:20 UTC 
Also, doc type and doc text have already been provided. I think all of this takes care of the needinfo.
Comment 13 Manisha Saini 2023-12-04 06:50:12 UTC 
Hi Venky, Frank

The target release is set to 7.1 and the bz doc text is added in 7.0 release notes.
Could you please confirm if the fix is there in RHCS 7.0 or not?
If not, should we remove the doc text from 7.0 release notes?
Comment 16 Frank Filz 2023-12-04 14:36:37 UTC 
The feature was tested as working, however, it exposed a serious memory growth issue that needs to be addressed, so we withdrew the feature for 7.0 and moved it to 7.1.
Comment 18 Greg Farnum 2024-03-27 14:48:20 UTC 
This has been rescheduled for 8. Dhairya's been working on testing and bug fixes in async.
