[Bug]: 6 TB Drive Only Shows 85.2 GB Upon Connection #143

Closed iJasonWade closed 1 year ago

iJasonWade commented 1 year ago

Describe the Bug

I have a 6 TB hard drive I am using for timemachine, but when I connect to it from my Mac it only shows 85.2 GB available.

What is the backing filesystem that is used on /dev/sdb? Are there really not any partitions? The only thing I can immediately think of is that samba is incorrectly interpreting the free space due to the filesystem but it's hard to say.

iJasonWade commented 1 year ago

There is only one partition, it is an ext4 format, maybe I should format it again and create a partition?

mbentley commented 1 year ago

Ah! I missed a small but very important detail. You're setting TM_USERNAME=jason which means that your persistent data path is actually /opt/jason in the container. Update your volume from:

- '/home/jason/mnt/timemachine:/opt/timemachine'

to:

- '/home/jason/mnt/timemachine:/opt/jason

Otherwise, it's detecting the amount of free space on the disk where Docker is and it will be storing data inside the container, not on a persistent volume.

mbentley commented 1 year ago

144 from earlier this morning added detection for what filesystems are found in the subdirectories under /opt. I also just added a check in #145 to output a warning message if the detected filesystem is overlay, which it would in most cases where the volume isn't mounted outside.

mbentley commented 1 year ago

Example output:

$ docker run -it --rm -e TM_USERNAME=jason mbentley/timemachine:test
