I recently got a CRS328-24P-4S+ and am having an issue going from 6-42-5 to 6-42-6. The device came with 6-41 on it and I was able to upgrade it via Winbox to 6-42-5. I went to system-packages and had it download and install. Everything worked fine and I even updated the firmware.
The issue now is that the device only has 16.0 MB of drive space and 12.7 MB is used. When I try to upgrade the device now it tells me that it doesn't have anymore space. When I look at "files" I don't see anything under "flash" so not sure what to do. Could the issue be something to do with the SWOS as I am running the device in RouterOS.
