Omega1: Am I missing storage space?



  • I booted up my Omega1 for the first time today and immediately connected to WiFi and then ran oupgrade. With my device running and logged in through a serial emulator, I ran df -k and was surprised at the result:

    # df -k
    Filesystem           1K-blocks      Used Available Use% Mounted on
    rootfs                    7552       500      7052   7% /
    /dev/root                 7680      7680         0 100% /rom
    tmpfs                    30576        96     30480   0% /tmp
    /dev/mtdblock3            7552       500      7052   7% /overlay
    overlayfs:/overlay        7552       500      7052   7% /
    tmpfs                      512         0       512   0% /dev
    
    

    This seems to show that my file system is less than 7.5MBytes in size. I had assumed that the filesystem would have been ~16MBytes. Is there a step I missed or some other recipe that I should have been performing.

  • There is some sort of overlay / merging going on..
    While the article is about extending storage the top part of the article may be helpful in the explanation of how the overlayfs works.

  • @None-None
    If you or someone else were to run df -k, what do you see as the disk areas on your system?



  • If I recall some documentation I've read, anything installed will reduce by that much the available storage. This is a reason why the Omega2 was created, and also why an optional SD Card connector also added.

  • @Neil-Kolban as "None None" mentioned, much memory the onion1 not has. The image will be loaded from the rom into ram ... so ... you can duplicate this value and it makes almost this 16MB you mentioned.
