Hello! I have a /home partition that is almost full, and there is another partition nearby with a lot of free space. I would like to reduce the size of this neighboring partition and add the freed space to /home. I would like to do this safely, without using a Live USB or bootable flash drive. Is this possible?
! thank you, but maybe you can tell me, how can I do it on a live system, please?
Don’t do it on a live system.
Use a live image with gparted (most normal distros come with it) start it and the gui should be pretty self explanatory.
Use cfdisk and just edit the partitions.
Please note that if you do this without first resizing the filesystems on the partitions, you are very likely to lose data. You cannot safely shrink a mounted partition.
