I have got my OMV 4 up and running but the system disk (24Gb out of 60gb occupied) is quite full and I'd like to do some maintenance and clear some space.
I did run Apt-get clear and recovered 1Gb but I think there is something huge to delete.
I'm not an expert of linux, just a user of OMV.
One more problem is that I lost my password for root user, but I still have access via ssh with my admin user/password (not sure if it is enough or if i should try and reset the root password, if yes how to?)
Thanks for any help
