--0000000000004fe8ff0582dbe695 Content-Type: text/plain; charset="UTF-8" Hi all, 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 request of rquota-v1 and FreeBSD-12.0 sent request of rquota-v2. Then we trace the code 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 failure 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 diff 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 find some solution from FreeBSD.
