My take on diagnostics is: FWIW, "others" have tried changing /home/egreshko 2001:b030:112f:2::0/64(rw,sync,insecure,no_root_squash,no_subtree_check) to /home/egreshko 2001:b030:112f:2::0/64(rw,sync,no_root_squash,no_subtree_check) And the mount from an F33 system still succeeds. The entry for "man exports": secure This option requires that requests not using gss originate on an Internet port less than IPPORT_RESERVED (1024). This option is on by default. To turn it off, specify insecure. (NOTE: older kernels (before upstream kernel version 4.17) enforced this re‐ quirement on gss requests as well.) /run/sysconfig/nfs-utils had: GSS_USE_PROXY="yes" -- wonder if GSS is somehow at play here?
On my centos7 system.... [root@cos7 ~]# uname -r 3.10.0-1160.15.2.el7.x86_64 [root@cos7 ~]# cat /run/sysconfig/nfs-utils RPCNFSDARGS=" " RPCMOUNTDARGS="" STATDARGS="" SMNOTIFYARGS="" RPCIDMAPDARGS="" GSSDARGS="" BLKMAPDARGS="" GSS_USE_PROXY="yes" nfs-utils-1.3.0-0.68.el7 And, since it is now 05:40, I modified the exports file to be simply /home/egreshko 2001:b030:112f:2::0/64(rw) And from an F33 client which is the host of the the centos7 VM. [root@meimei ~]# mount -v cos7:/home/egreshko /mnt mount.nfs: timeout set for Fri Feb 26 05:45:37 2021 mount.nfs: trying text-based options 'vers=4.2,addr=2001:b030:112f:2::41,clientaddr=2001:b030:112f:2::2' [root@meimei ~]# df -T | grep mnt cos7:/home/egreshko nfs4 29599744 5328128 24271616 19% /mnt So, I still can't find a way to duplicate the OP's problem without specifically changing a config file. I even when to far as to mount the file system with a F33 "located" in the USA and the centos7 system in Taiwan. [root@acer ~]# mount -v [2001:b030:112f:2::41]:/home/egreshko /mnt mount.nfs: timeout set for Fri Feb 26 06:03:52 2021 mount.nfs: trying text-based options 'vers=4.2,addr=2001:b030:112f:2::41,clientaddr=2001:440:66:cce::2' [root@acer ~]# df -T | grep mnt [2001:b030:112f:2::41]:/home/egreshko nfs4 29599744 5325056 24274688 18% /mnt -- People who believe they don't make mistakes have already made one. _______________________________________________ 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 Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
