I’ve installed Leap 42.2 on a new system with a 1T HD. I did as I always do, I specified Ext4 rather than BTRFS. The installation went through OK. When the system rebooted after the installation, I noticed that the root partition, /dev/sda2 is only 10G (well, 9.8G) in size. On my system, 500G HD, the root file system is 20G. When I went to resize the partition it in Yast, I would not let me, telling me that 10G was it. I’ve used already about 45% of the root partition. Is this, or will this be, a problem? Does the 1T drive have anything to do with this?
It may be a problem IMHO you should have 20+ gig min for root. But it depends on how you use it and how many application you may install
You can’t resize unless there is free space at then end of a partition. So you would need to resize and move other partition to allow expansion space
I suspect that when you changed to ext4 since you were no longer using default sizes and an absolute minimum was set and you did not adjust it. ALWAYS read and under stand the partition scheme shown before accepting it. NEVER assume that any installer can guess what you want.
When you first installed, the default layout assumed you might download and store an enormous amount of personal files, so likely created a very large /home partition.
If you intend to install a lot of applications and not store so many files in your /home partition, then you might end up with a /home partition that’s not used much while your root partition fills up quickly.
You can view your existing use of space on each of your mounted partitions by running the following command
df -H
If you want to change the allocation of space, for instance shrinking your /home partition and giving that space to your root partition, I recommend you use gparted live. Unlike the regular gparted application, gparted live is a LiveCD which enables you to make changes to your root partition immediately (because it’s not in use) without a reboot.
