(I'm not sure if this feature has hit production yet, but it's been available in at least alpha for a year and a half.)

This looks like a one-liner to me (add to the validation function in resource_kubernetes_persistent_volume.go:90), but I don't have an environment I can test it in.
Hello! Thank you for opening this issue @joey-squid, based on the current state of ReadOnceWritePod on the feature gate list, we will not be adding it just yet due to it still being in alpha.
This is also mentioned in our FAQ, in order to prevent any breaking changes we refrain from using features that are not in the beta stage
Makes sense and thanks. I didn't know about that list, and thought it was already past alpha for some reason. Would you like me to close out this issue or leave it open for when it does hit beta?
@pbecotte I just checked the feature gates and you're right. They've moved it into beta with the release of 1.27 back in april!

Hi all and happy new year!
My company isn't using Terraform for k8s anymore, so I don't see myself making this PR. As I mentioned earlier, it's probably a very simple change, but I'll leave it to people who would actually use (and therefore test) it.

k8s 1.29 (released December 13, 2023) has ReadWriteOncePod as GA.
It's at the top of their graduations to stable list.
I just tried to use it and was surprised it wasn't recognized. Google brought me here.
Just bumping this, would be good to see this implemented. Is it on the radar/roadmap?
