Hi,

 

I am trying to mount a NFS share from a NAS, it work flawlessly on my pc (Arch) but on my odroid (Armbian), only NFSv3 works, not NFSv4.

$ sudo mount.nfs -vvv 10.10.0.131:/volume1/Owncloud data rw       
mount.nfs: timeout set for Wed Jun  1 12:01:19 2016
mount.nfs: trying text-based options 'vers=4,addr=10.10.0.131,clientaddr=10.10.0.130'
mount.nfs: mount(2): No such file or directory
mount.nfs: trying text-based options 'addr=10.10.0.131'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: trying 10.10.0.131 prog 100003 vers 3 prot TCP port 2049
mount.nfs: prog 100005, trying vers=3, prot=17
mount.nfs: trying 10.10.0.131 prog 100005 vers 3 prot UDP port 42889

Maybe a package is missing ? I have installed nfs-common, I think that's all I need but I have noticed I have 'gvfs-nfs' also installed on my Arch, I don't know what it is.

 

Another problem is that the owner of the mounted directory is set to 999, I don't know what user it is. It weird because on my pc it's just root or "me" if I add the 'user' option. How can I get the username that 999 refer to ? Is it a user of the NAS or of local system ?

no idea, but what do you get with

zcat /proc/config.gz | grep NFS

 

 

 

gr@bpi:~$ zcat /proc/config.gz | grep NFS
# CONFIG_USB_FUNCTIONFS is not set
CONFIG_KERNFS=y
CONFIG_NFS_FS=y
CONFIG_NFS_V2=y
CONFIG_NFS_V3=y
CONFIG_NFS_V3_ACL=y
CONFIG_NFS_V4=y
CONFIG_NFS_SWAP=y
CONFIG_NFS_V4_1=y
CONFIG_NFS_V4_2=y
CONFIG_PNFS_FILE_LAYOUT=y
CONFIG_PNFS_BLOCK=m
CONFIG_PNFS_FLEXFILE_LAYOUT=m
CONFIG_NFS_V4_1_IMPLEMENTATION_ID_DOMAIN="kernel.org"
# CONFIG_NFS_V4_1_MIGRATION is not set
CONFIG_ROOT_NFS=y
# CONFIG_NFS_USE_LEGACY_DNS is not set
CONFIG_NFS_USE_KERNEL_DNS=y
CONFIG_NFSD=y
CONFIG_NFSD_V2_ACL=y
CONFIG_NFSD_V3=y
CONFIG_NFSD_V3_ACL=y
CONFIG_NFSD_V4=y
# CONFIG_NFSD_PNFS is not set
# CONFIG_NFSD_FAULT_INJECTION is not set
CONFIG_NFS_ACL_SUPPORT=y
CONFIG_NFS_COMMON=y

 

 

The quick and dirty way to find the user id assigned to that number is to do the following as root

 

getent passwd "999" | cut -d: -f1

 

 

 

can you post the output of /etc/exports

 

the default for most nfs installs is v4, when i install nfs and configure it i do it the following way.

 

apt-get update ; apt-get upgrade ; apt-get install autofs nfs-kernel-server nfs-common --install-recomends -f -y ; sync ; reboot ;

 

 

BTW - im currently working on a howto around NFS over on the doozan forums so if you want to have a look there that may help as well
