I have only done two NFS commits within that range. 1 - A trivial one that adds two new arguments always specified as 0, which has no change in semantics. 2 - One that only affects NFSv4 during dismount, so it shouldn't affect an NFSv3 mount.
Some things to try: - get rid of rpc.statd and rpc.lockd and do the mount with the "nolockd" option - capture packets during the mount and look at them in wireshark, to see what is going on the wire. - see if there are any patches applied to your net interface driver during that commit rev. range - if you have any kind of firewall setup, get rid of that and see if that helps Good luck with it, rick ________________________________________ From: Michael Butler <i...@protected-networks.net> Sent: Friday, September 29, 2017 9:09:35 PM To: freebsd-current Cc: rmack...@freebsd.org Subject: Can't NFS mount ZFS volume Both client and server have been upgraded from SVN r324033 to r324089 Now I can't mount a ZFS dataset over NFS :-( imb@toshi:/home/imb> sudo /sbin/mount -t nfs vm01:/usr/local/exports/ /mnt imb@toshi:/home/imb> mount /dev/ada0s3a on / (ufs, local, soft-updates) devfs on /dev (devfs, local, multilabel) procfs on /proc (procfs, local) linprocfs on /usr/compat/linux/proc (linprocfs, local) linsysfs on /usr/compat/linux/sys (linsysfs, local) vm01:/usr/local/exports on /mnt (nfs) imb@toshi:/home/imb> sudo ls -l /mnt ls: /mnt: Input/output error The server shows the mount as being registered .. imb@vm01:/home/imb> showmount -a All mount points on localhost: toshi.auburn.protected-networks.net:/usr/local/exports It takes some time to complete an umount request but it does complete, Any thoughts? imb _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
