Thanks Neil..Yes, that will be a great add to Ceph’s feature list.. For now, probably I should use the tool that Ben pointed out. Regards Somnath From: Neil Levine [mailto:nlevine@xxxxxxxxxx]
There is an initial prototype of the NFS layer to RGW using Ganesha. Yehuda can probably give an update on its status. The use case for it is exactly as you describe: to allow you to migrate data of NFS shares to the S3-object store. It's
not going to be high performance or be feature rich but hopefully will do enough to allow data migration.

We have PB level of data in NFS share which needs to be moved to the Ceph cluster and that’s
why I need your valuable input on how to efficiently do that. I am sure this is a common problem that RGW users in Ceph community have faced and resolved
J . I can think of the following approach. Since the data needs to be accessed later with RGW/S3 , we have to write an application that can PUT the existing files as objects over RGW+S3 interface to the cluster. Is there any alternative approach ?
There are existing RADOS tools that can take files as input and store it in a cluster , but, unfortunately RGW probably will not be able to understand those.
IMO, there should be a channel where we can use these rados utility to store the objects in .rgw.data pool and RGW should be able to read the objects. This will solve lot of data
migration problem (?). Also, probably this blueprint (https://wiki.ceph.com/Planning/Blueprints/Infernalis/RGW%3A_NFS)
of Yehuda’s trying to solve similar problem… Anyways, Please share your thoughts and let me know if anybody already has a workaround for this. Thanks & Regards Somnath
