This was first disabled on groovy, the first ubuntu release after focal: root@g1:~# grep NFS /boot/config-5.8.0-59-generic |grep UDP CONFIG_NFS_DISABLE_UDP_SUPPORT=y

NFS over UDP on modern networks (1Gb+) can lead to data corruption caused by fragmentation during high loads. """ I'll leave it to the kernel team to comment further. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1964093 Title: nfsver=3,udp not working anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1964093/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
