So I recently moved most of my docker storage to a second hard drive, called “storage.” After a system restart, docker is creating a folder called “storage,” forcing the physical drive to be renamed “storage1.” How do I prevent this from happening?
I am using Xubuntu.
Edit: As suggested, it was indeed my system spinning up Docker before mounting the internal disk. The solution (should work on most Unix-like systems) was to manually add a line to /etc/fstab as follows: First get the UUID for the problem drive
~$ sudo blkid -s UUID
The output will show your drives and the UUID of each. Then edit the following file:
~$ sudo mousepad /etc/fstab #{or use your choice of editor, i.e. nano}
Add the following line:
/dev/disk/by-uuid/{UUID number copied from blkid output} /destination/of/your/drive ext4 defaults 0 0
Of course replace {UUID number copied from blkid output}
and /destination/of/your/drive
and set defaults & parameters as needed. These worked for me.
Restart the system and the drive should be forced to mount before docker starts. This seems to be a known issue with certain docker setups.
It looks like you’re relying on media automounting to access the drive, but this is happening too late for Docker.
I would suggest creating the empty folder and explicitly adding the mount to
/etc/fstab
instead. This should mount early enough, and even if it doesn’t it needs an empty folder for the mount point anyway.Edit: Make sure you reference the partition by UUID, because the device name of USB devices sometimes change after a reboot.
Thanks - this was the solution. I’ve updated the post to reflect the solution I used.
Agreed. Needs to be a required mount in fstab. System won’t even start then if the mount fails, docker always has access
