Description Soumya Koduri 2015-06-25 06:52:40 UTC

+++ This bug was initially created as a clone of Bug #1235542 +++

Description of problem:
Any directory or file creation should result in cache-invalidation requests sent to parent directory. However that is not the case currently due to a bug while processing these requests in the upcall xlator. We need to do invalidation checks on parent inode.

Comment 2 Soumya Koduri 2015-06-25 06:53:27 UTC

Fix is under review in upstream.

Comment 3 Soumya Koduri 2015-06-25 06:54:30 UTC

Without the fix, in a multi-headed ganesha, directory/file creations via one NFS-ganesha head will not get reflected on mounts connected to other server.

Comment 7 Saurabh 2015-07-14 05:50:22 UTC

The tests that I did were related to creating/removing files, directories and appending data to a file, while trying to access the same from different client where mount is done from a different server. 

The data modification was seen accordingly.
