mount. helper program.

Hi, I would like to get some help. I’m pretty confused, of what is going on, because I’ve never had any issues with NFS shares. I created 2 vms to test some stuff.

VM A is a share source and /etc/exports looks like this

tstadmin@luks-tst1:~$ cat /etc/exports

/etc/exports: the access control list for filesystems which may be exported

to NFS clients. See exports(5).

Example for NFSv2 and NFSv3:

/srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)

Example for NFSv4:

/srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)

/srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check)

# /mnt/lv00/ 192.168.1.168(rw,sync,no_subtree_check) sudo exportfs -a gives no output so I guess everything works correctly

VM B is a receiving side and it is making problems, please review this command:

tstadmin@luks-tst2:/mnt/share$ sudo mount -t nfs 192.168.1.168:/mnt/lv00 /mnt/share/lv00 mount: /mnt/share/lv00: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program.

tstadmin@luks-tst2:/mnt/share$ sudo mount -o nolock -t nfs 192.168.1.168:/mnt/lv00 /mnt/share/lv00 mount: /mnt/share/lv00: bad option; for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount. helper program. I have no idea, what is wrong, ip address is correct - I use the same address to ssh. Could you please help me figure out this problem? I don't understand what this output tells me to do.

2 lord_EarlGray OP • 4y ago I have installed nfs-utils (both servers are Ubuntu Server 18). Now it changed to:

tstadmin@luks-tst2:/mnt/share$ sudo mount.nfs 192.168.1.168:/mnt/lv00 /mnt/share/lv00 mount.nfs: requested NFS version or transport protocol is not supported How is that possible? Both server have the same os version, how is that possible that they have different nfs versions?

Do you have a /sbin/mount. helper program?

1 u/OkPrune711 avatar OkPrune711 • 9mo ago You have to update NFS package on server where you are going to share NFS (tstadmin@luks-tst2), and Install NFS utilities dnf install nfs-utils. lastly, enable NFS services on server systemctl enable –now nfs-server.
