I'm not going to lose any sleep over it. But I thought I had it confined to V4 with the entry in /etc/nfs.conf. [root@meimei ~]# mount -t nfs -o nfsvers=3 f30k:/home /mnt mount.nfs: requested NFS version or transport protocol is not supported But of course [root@meimei ~]# mount -t nfs -o nfsvers=4 f30k:/home /mnt [root@meimei ~]# df | grep mnt f30k:/home 29110528 10145024 17463808 37% /mnt And....

Maybe I'll track down tomorrow why that is. -- If simple questions can be answered with a simple google query then why are there so many of them? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
