One thing not in any of the documentation I have found are the extra options required for the export. I followed all the docs and it was still failing.

I had to add, “sync,no_subtree_check,all_squash,anonuid=36,anongid=36”, to my export in order to get it to work.

This is invalid configuration. See RHV docs for proper configuration:

https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html/administration_guide/sect-preparing_and_adding_nfs_storage#Preparing_NFS_Storage_storage_admin

But, why this issue starting from updating  4.30.32-1 to  4.30.33-1? Withowt any another changes.

I guess you had wrong permissions and ownership on the storage before, but vdsm was not detecting

the issue because it was missing validations in older versions. Current version is validating that creating

and deleting files and using direct I/O works with the storage when creating and activating a storage

domain.
