hey i have been using Fedora for several years, but so far i don’t know how to troubleshooting for increase more disk in Linux/Fedora , i always re install if there is new Fedora coming, i always do this for years, really that is true ! because there is few tutorial about how to increase more free this into file system, and sometimes i dont understand follow by their guide but always failed, so than i spend much times for few days to debug it better i re install.
when i install Fedora 31 now in my Laptop, and i have increate more space on /usr, but unfortunately the space i put is not enough and i think i have to make more free disk on /usr , here is the ss of my disk with df -h -T
i was having problem on /tmp because not make big space disk on there before so i increase it and now it only use for 1%, i want take 2.5GB on /tmp and move it to /usr, is that possible ? is that any command line to make this magic easier ? or there is a tool for make this happen ?
Firstoff, if you’re updating by reinstalling anyways, you might want to simply wait for Fedora 33 to come out in a few weeks (or try the beta release right now), backup your /home elsewhere, wipe the disk and reinstall Fedora with it’s default partitioning. That will let Fedora use btrfs as the root filesystem, which means you will no longer have to care about the sizes of different partitions (look up btrfs subvolumes for details on how this works). I think that will be of great benefit, especially given your relatively small hard disk.
Now, to your question:
/tmp is normally a tmpfs, i.e. mounted into RAM - you can simply revert to that. Can you post the content of /etc/fstab?
Anyway, your partition layout is rather funky
you have a large / partition, but its main space consumers (/usr and /var) are on separate partitions, leaving / fairly empty
you have a large /var partition but don’t use it
so you could use your harddisk space way more efficiently by doing some fundamental repartitioning, which is why I’d advise to go the Fedora-33-with-btrfs route.
