https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236179 Bug ID: 236179 Summary: Quota on FreeBSD 12.0 is not working with NetApp Product: Base System Version: 11.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: j.nethdd@gmail.com Created attachment 202519 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D202519&action= =3Dedit Our changes for `quota.c` to work around with NetApp mount point. We meet a quota problem with NetApp after upgraded system from FreeBSD-11.2= to FreeBSD-12.0. The quota command in FreeBSD-12.0 returned nothing on any NetApp mount point which works good in FreeBSD-11.2. So we trace the rpc.rquotad packet with tcpdump, and found that the difference is quota of FreeBSD-11.2 sent reques= t of rquota-v1 and FreeBSD-12.0 sent request of rquota-v2. Then we trace the cod= e of quota which is located in '/usr/src/usr.bin/quota/quota.c' to find is there= any way to send only rquota-v1 request or resend rquota-v1 request after failur= e of rquota-v2 request. We found that quota will try rquota-v1 if the v2 request return "Program Version Mismatch", but NetApp seems have a non-standard behavior that would response "Program Not Registered" and leads quota exit without re-trying v1 request. Link below is the issue of libtirpc on Linux caused by the same non-standard behavior: https://sourceforge.net/p/libtirpc/mailman/message/36337416/ We patch one line code and it works on our environment for temporary. The d= iff output of our patch is attached in the letter. We wonder if this patch can be merged into FreeBSD-12.0, or is there any solution can force quota to use rquota v1 (add an option for this, maybe?) Because NetApp does not want to fix this behavior since 2008, we want to fi= nd some solution from FreeBSD.
