Mounting an SMB volume with autofs

filemaker_server_smb_mount.md

Our demo share

Windows server	demoserver
Share	demoshare
Mount path on the FileMaker server	/mnt/demoserver

Install the Ubuntu packages

apt-get install autofs cifs-utils

Create the mount point

sudo mkdir /mnt/demoserver
sudo chmod 700 /mnt/demoserver
sudo chown fmserver:fmsadmin /mnt/demoserver

Get the fmserver user uid / gid

We need this for the automount file in the next step

id -u fmserver
id -g fmserver

For this demo, I assume the user id is 1001 and the group id is 1002.

Configure the mount

Add this line to /etc/auto.master

/mnt/demoserver /etc/auto.demoserver --timeout=600 --ghost

Create the automount file

Create the file /etc/auto.demoserver

# Automatically mount the demoserver share
# autofs uses the ticket cache in /tmp/krb5cc_0

demoshare -fstype=cifs,vers=3.0,sec=krb5,cruid=0,uid=1001,gid=1002 ://demoserver/demoshare

Start autofs and make it start automatically on reboot

sudo systemctl enable autofs
sudo systemctl start autofs

Use the file share

cd /mnt/demoserver/demoshare
