Question

How to set permissions on boot for a Volume

Hi,

I’ve managed to set up a volume and attached it to my droplet in the storage folder of my project. On boot this is done by fstab by the following line.

/dev/disk/by-id/scsi-0DO_Volume_volume-ams3-01 /path/to/mount-point ext4 defaults,nofail,discard 0 0

However after every reboot I need to set the permissions by performing:

sudo chown -R forge:forge /path/to/mount-point

Otherwise the forge user has no permissions on the volume. Can this be automated and is there a best practice for this?

Thanks in advance.

Hey There,

What I can suggest is the following:

  • Create a scriptfile with touch scriptfile
  • Add the following to it:
#!/bin/bash
sudo chown -R forge:forge /path/to/mount-point
  • Execute the following commands:
chmod +x scriptfile
chmod 755 scriptfile
mv *scriptfile* /etc/init.d/
touch /etc/rc3.d/S01scriptfile
update-rc.d scriptfile defaults
  • You just added your script to your boot sequence and should be good to go!

As an alternate solution, you can use crontab and set a @reboot line in there - https://www.cyberciti.biz/faq/linux-execute-cron-job-after-system-reboot/

Hope this helps and make sure to let me know if it did!
