[ceph pacific 16.2.9]
When creating a NFS export using "ceph nfs export apply ... -i export.json" for a subdirectory of /cephfs, does the subdir that you wish to export need to be pre-created or will ceph (or ganesha) create it for you?
I'm trying to create an "/shared" directory in a cephfs tree and export it using a JSON spec file, but the nfs-ganesha log file shows errors because it cannot mount or create the desired directory in cephfs. If I manually create the directory prior to applying the export spec, it does work. But it seems that ganesha is trying to create it for me so I'm wondering how to make that work.

The JSON spec used looks like:
{
"export_id": 2,
"transports": [ "TCP" ],
"cluster_id": "ceph",
"path": "/shared",
"pseudo": "/shared",
"protocols": [4],
"access_type": "RW",
"squash": "no_root_squash",
"fsal": {
"name": "CEPH",
"user_id": "nfs.ceph.2",
"fs_name": "cephfs"
}
}
thanks,
