These are rough notes from whatever I was working on, interested in or thinking about at the time. They vary greatly in quality and length, but prove useful to me, and hopefully to you too!

The Important Files: Part 6

Trying to fix operation not permitted when trying to write to NFS share.

Using SMB and NFS together is perhaps not safe:

Let’s get rid of the NFS share and just use SMB.

Install the Samba client package:

pacman -S smbclient

Remove entry for NFS share.

vi /etc/fstab

Create empty Samba configuration file. It is necessary in order to use smbclient.

sudo touch /etc/samba/smb.conf

Try and manually list which SMB shares are available.

[marbs@cpe1704tks ~ ]$ smbclient -L
Enter WORKGROUP\marbs's password:

        Sharename       Type      Comment
        ---------       ----      -------
        media           Disk
        IPC$            IPC       IPC Service (FreeNAS Server)
Reconnecting with SMB1 for workgroup listing.

        Server               Comment
        ---------            -------

        Workgroup            Master
        ---------            -------
        WORKGROUP            FREENAS

In the FreeNAS UI, select the SMB share, selected advanced, and enable “Allow Guest Access”.

modprobe -c | grep cifs
sudo mount -t cifs // /mnt/media -o guest,vers=3.0


mount error : cifs filesystem not supported by the system mount

Then after reboot:

[marbs@cpe1704tks ~ ]$ modprobe -c | grep cifs
softdep cifs pre: ccm
softdep cifs pre: aead2
softdep cifs pre: sha512
softdep cifs pre: sha256
softdep cifs pre: cmac
softdep cifs pre: aes
softdep cifs pre: nls
softdep cifs pre: md5
softdep cifs pre: md4
softdep cifs pre: hmac
softdep cifs pre: ecb
softdep cifs pre: des
softdep cifs pre: arc4
alias fs_cifs cifs

Try mounting again:

sudo mount -t cifs // /mnt/media -o guest,vers=3.0

It works!

But I can only read, not write…

sudo umount /mnt/media

Remount as a user rather than as guest:

sudo mount -t cifs // /mnt/media -o username=marbs,vers=3.0

Now update /etc/fstab to automatically mount the disk:

# /mnt/media
#   /mnt/media  nfs  noauto,x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0
//  /mnt/media  cifs  noauto,x-systemd.automount,x-systemd.device-timeout=10,x-systemd.idle-timeout=1mind,username=marbs,password=mypassword,vers=3.0 0 0

For more information on the x-systemd options see here.

Now reboot for the changes to take effect.

Can re-mount manually now with:

systemctl restart mnt-media.automount
