I'm running a modified WD MyCloud (Gen 1) NAS with Debian 8 (Jessie) installed on it.
Due to the nuances of the device, I can't resize the root partition, and am struggling with space on it.
To remedy this, I've rsynced the
/usr directories on to the main data partition.
I've then added the following lines to the
/data/rootfs/var /var none defaults,bind 0 0 /data/rootfs/usr /usr none defaults,bind 0 0
Upon rebooting, I find that the
/var directory has successfully been mounted, but that the
/usr directory has not.
If I then run
mount -a, I get no errors, and the
/usr directory is correctly mounted.
What's going wrong?
