Asked by S Di
This is my fstab
LABEL=cloudimg-rootfs / ext4 discard,errors=remount-ro 0 1
LABEL=UEFI /boot/efi vfat umask=0077 0 1
/dev/sda /home/newfolder ext4 defaults 0 0
after a reboot /home/newfolder is replaced by
/dev/sda 50G 16K 47G 1% /mnt/volume_lon1_01
until I umount /dev/sda then df -h shows this
/dev/sda 50G 16K 47G 1% /home/newfolder
How do I get /dev/sda to mount on /home/newfolder on reboot?

Heya,
The issue you’re facing seems to be that another process or service is mounting your
/dev/sdapartition to/mnt/volume_lon1_01at startup before it can be mounted to/home/newfolderas specified in your/etc/fstab.A few things you could try to solve this:
Check for Cloud-Init or Other Mounting Services: If you’re on a cloud-based server, there might be a configuration in place (such as cloud-init) that mounts volumes at startup. You would need to change this configuration so that
/dev/sdais mounted to/home/newfolderinstead of/mnt/volume_lon1_01. If you’re using a service like DigitalOcean, you can configure this through the volumes settings.Use UUID Instead of Device Name: The device name
/dev/sdacan change based on the order the system detects your drives. Using the UUID of the drive is a more robust method. You can find the UUID by running the commandblkid /dev/sda. Replace/dev/sdawithUUID=your-uuidin/etc/fstab.Ensure Correct Syntax in
/etc/fstab: Make sure the syntax in your/etc/fstabfile is correct. Here’s an example of how your line could look/home/newfolderis a subdirectory of another mount point, ensure that it is mounted after that mount point. The order of entries in the/etc/fstabfile matters.Hi there,
Does this happen after every restart? Your
/etc/fstabfile appears to be set up correctly, but it seems like something else is mounting/dev/sdato/mnt/volume_lon1_01before thefstabentries are processed.Do you by any chance have any other services or configurations that are auto-mounting the drive, like
systemd,udev, orautomount?Also, does the
/home/newfolderexists before the system tries to mount/dev/sda? If the directory doesn’t exist when the system is trying to mount, it will fail.What I usually do is to run
sudo mount -amanually to check if myfstabfile has any syntax errors before actually rebooting the server.Let me know how it goes!
Best,
Bobby
