[Dovecot] rquota RPC with netapp filer

Hello list,

with dovecot 1.2 on AIX rquota RPC calls fail with

quota-fs: remote ext rquota call failed: RPC: 1832-012 Program/version mismatch

when using a netapp filer.

This is what netapp says:

Bug ID 97288 Title Support requested for rquota version 2 Bug Severity 5 - Suggestion Bug Status Closed Product Data ONTAP Bug Type NFS Description Linux has implemented its own extensions to the rquota protocol as a version 2 of that protocol. ONTAP only supports v1 as that is the only version defined by Sun, the owner of that RPC program number. Workaround - Fixed-In This bug is not scheduled to be fixed, you may opt to Version open a technical support case if you would like to contact Network Appliance regarding the status of this bug. A complete list of releases where this bug is fixed is available here.

So this should be no AIX specific problem.

Using the attached rquota.x fixes the problem. In addition you have to disable group quota checking by adding "user" to your "quota" definition. Otherwise you'll see:

quota-fs: rquota not compiled with group support

Regards, Ralf
