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?

Hi there,
Does this happen after every restart? Your /etc/fstab file appears to be set up correctly, but it seems like something else is mounting /dev/sda to /mnt/volume_lon1_01 before the fstab entries are processed.
Do you by any chance have any other services or configurations that are auto-mounting the drive, like systemd, udev, or automount?
Also, does the /home/newfolder exists 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 -a manually to check if my fstab file has any syntax errors before actually rebooting the server.
Let me know how it goes!
Best,
Bobby
Heya,
The issue you’re facing seems to be that another process or service is mounting your /dev/sda partition to /mnt/volume_lon1_01 at startup before it can be mounted to /home/newfolder as 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
UUID=your-uuid /home/newfolder ext4 defaults 0 2
- Reorder Mounting Points: If
/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.
