Hi,
Since its working on your test machine, most likely could be NFS
client-side issue. Please check if there are any kernel fixes between
those versions which may have caused this.
I see similar issue reported in below threads [1] [2]. As suggested
there, could you try disabling kerberos module and specify "sec=sys"
during mount. If the issue persists, please use "-vvv" option during
mount to get more verbose output.
Thanks,
Soumya

Hi community,
Maybe someone could help me with this one: half the time, mounting
nfs-ganesha NFS4 exports failed at boot. I’ve seach a lot about this
problem but because it doesn’t happen at every boot it’s difficult to
pinpoint the exact problem. It mount perfectly after boot is completed.
-------------------------
-Debian 9 (uptodate) on all Gluster servers and clients (4 apache2 web
servers).
-Gluster version 6.7
-NFS-Ganesha version 2.8.3
-NFS 4.2
-fstab exemple: 192.168.11.90:/dev /data nfs4
noatime,nodiratime,vers=4.2,_netdev 0 0
-NFS-Ganesha export exemple:
EXPORT {
Export_Id = 2;
Path = "/dev";
Pseudo = "/dev";
Access_Type = RW;
Squash = No_root_squash;
Disable_ACL = true;
Protocols = "4";
Transports = "UDP","TCP";
SecType = "sys";
FSAL {
Name = "GLUSTER";
Hostname = localhost;
Volume = "dev";
}
}
-Dmesg log: NFS: nfs4_discover_server_trunking unhandled error -512.
Exiting with error EIO
-Systemd log:
systemd[1]: Failed to mount /data.
systemd[1]: Dependency failed for Remote File Systems.
systemd[1]: remote-fs.target: Job remote-fs.target/start failed
with result 'dependency'.
systemd[1]: data.mount: Unit entered failed state.
---------------------------
I tried to reproduce the same problem with a test machine but it mount
perfectly at every reboot. Then, I’m pretty sure the problem is on my
clients. Also, no problem with fuse mount.
Any help or direction to follow will be greatly appreciated.
Thank you
Renaud Fortier
