1. Can you still log in to the terminal for OMV (not the GUI).
2. Can you still access the storage from other computers?
good morning and merry christmas.
I turned off all HDDs from the power, I left only the SSD with OMV4 active.
So I used the USB stick with the G-Parted software.
I found that all 20GB of the SDD was full.
I had left 35GB unallocated, so I created a single 55GB partition.
I rebooted, and from the WebGUI I put the username and password back, and by magic everything works.
Thanks to the help of gderf
it remains for me to find, the reason for the data overload on an SSD that I don't insert any files
