Red Hat Bugzilla – Bug 1235544
Upcall: Directory or file creation should send cache invalidation requests to parent directories
Last modified: 2016-01-19 01:14:38 EST
+++ 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.
Fix is under review in upstream.
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.
Below patches are submitted to address this issue - https://code.engineering.redhat.com/gerrit/#/c/51717/ https://code.engineering.redhat.com/gerrit/#/c/51718/
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.
