I just updated linux-image-5.15.0-18-generic to today's new version linux-image-5.15.0-22-generic.
Now with enabling "udp=y" in /etc/nfs.conf and the new kernel version I can mount the nfs-share on the jammy server from the koppix pxe initdrd (busybox mount) with nfs version 3 and udp. Only mounting jammy server from jammy client is still not possible with nfs3+udp. The diff of /boot/config-5.15.0-18-generic and /boot/config-5.15.0-22-generic shows no hints of NFS related changes in the kernel config. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1964093 Title: nfsver=3,udp not working anymore Status in linux package in Ubuntu: Confirmed Bug description: Package: nfs-kernel-server Architecture: amd64 Version: 1:2.6.1-1~exp1ubuntu1 nfsversion 3 with proto udp seems not to be supported by the nfs- kernel-server anymore. In Ubuntu 18.04 (nfs-kernel-server 1:1.3.4-2.1ubuntu5) it was still possible. I could mount with either tcp or udp: 1. tcp mount -o nfsvers=3 192.168.0.1:/srv/nfs/testshare /mnt mount|grep mnt: 192.168.0.1:/srv/nfs/testshare on /mnt type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.0.1,mountvers=3,mountport=59808,mountproto=udp,local_lock=none,addr=192.168.0.1) 2. udp mount -o nfsvers=3,udp 192.168.0.1:/srv/nfs/testshare /mnt mount|grep mnt: 192.168.0.1:/srv/nfs/testshare on /mnt type nfs (rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,proto=udp,timeo=11,retrans=3,sec=sys,mountaddr=192.168.0.1,mountvers=3,mountport=59808,mountproto=udp,local_lock=none,addr=192.168.0.1) Now in Ubuntu 22.04 I get the message: mount.nfs: an incorrect mount option was specified I tried to enable upd in /etc/nfs.conf in section [nfsd]: [nfsd] # debug=0 # threads=8 # host= # port=0 # grace-time=90 # lease-time=90 # udp=n udp=y # tcp=y # vers2=n # vers3=y But there was no effect. nfs3 with udp is needed by several busybox mount binaries in initrds of Knoppix and other live distributions used via PXE boot.
