@jsafrane and @qinpingli PTAL - links to docs for AWS EBS and Manila CSI Operators will be added in their related Release Notes entries when those Operator PRs are approved/merged for 4.5. Thanks!

@bobfuru For External provisioner for AWS EFS feature, I can confirm this feature is dropped from 4.4. But there is a user story in 4.2, so I don't know if we should move this feature to "Table 1".

@qinpingli By "dropped", do you mean "deprecated" (not "removed")? Also, which user story are you referring to in 4.2?

Based on your suggestion, I moved it from Table 2 to Table 1, indicating that it was still TP in 4.3 but deprecated in 4.4 and 4.5. If that is correct, we should probably also update 4.4 Release Notes.

Also, step 1 in the Persistent storage using AWS EFS -> Create the EFS provisioner procedure includes the quay.io/external_storage/efs-provisioner:latest container image in the spec. Based on this change for EFS external provisioner, is this sample still correct?

This is another PR to follow this. #22524 (comment)

@qinpingli Based on your comment in PR 22524, it sounds to me like EFS should be DEP in 4.2 and 4.3 because it wasn't tested, and - (Removed) in 4.4 and 4.5 because the image is not available for customers.
Two questions for you:

1. Is this a correct assessment? If so, I'll work with Cody to accurately reflect this info in 4.2+ Release Notes tables.
2. What does this mean for the 4.x EFS documentation (https://docs.openshift.com/container-platform/4.4/storage/persistent_storage/persistent-storage-efs.html)? Should all of it be removed starting from 4.4?

@bobfuru I synced with @huffmanca on this today. There should be clarifications coming for this soon. As I understand it, QE didn't test the AWS EFS provisioner for 4.x; however, I've heard it was still included in several versions of 4.x. Since it is TP, I don't think we can deprecate it in 4.2/4.3 because it was never supported. It would just go from TP → dropped.

[bobfuru]

Thanks, @codyhoag! Makes sense to move it from TP -> REM... seems that should be starting in 4.3.

Thanks, Bob. the assessment lgtm.

2. What does this mean for the 4.x EFS documentation (https://docs.openshift.com/container-platform/4.4/storage/persistent_storage/persistent-storage-efs.html)? Should all of it be removed starting from 4.4?

I agree with remove it starting from 4.4.

@qinpingli
Based on feedback from PM/Dev (#22524 (comment)), I'm going to leave the docs in 4.4 and @codyhoag will keep EFS as TP in the Release Notes for 4.2+. We can revisit when EFS is included in a CSI driver.

I've grouped all storage-related features in the same part of the Tech Preview Tracker table 2.

Can you please give it a final review and let me know if it looks good to you?
