## NAMEI vs. inode based file server
There are two different flavours of the AFS file server (the fs process): One uses inodes to store AFS data (volumes, files, metadata), the other uses real files.
The inode-based server needs a file system which supports access by inode and usually a special fsck is required so that the AFS data is not corrupted (since the server does some behind-the-scenes stuff with the file system). The NAMEI file server does not pose any unusual constraints on the underlying filesystem - it's an ordinary userspace program working with (silly-named) files.
You can easily see that you are using an NAMEI file server if there is a directory named `AFSIDat` and with subdirectories like `+` and `+1` in your `/vicep*`.

## Recommended Partition Types for use with [[OpenAFS]]
namei Server |
Server vicexx Partition Types |
Any system type |
Basically any filesystem you like, as the new namei file server does not do any fancy stuff behind the scenes but only accesses normal files (their names are a bit strange though). |

- **Question:** Does this table imply that clients can't use the NAMEI backend and still need a specific filesystem? Will this ever change?

- **Another Question:** Does this mean that you can use an NFS mount point as a /vicexx if you use a NAMEI fileserver?
