40GB Root Partition has 2.3GB Free. Steal From The Next Partition?
pacman -Syu fails with:
error: Partition / too full: 1276293 blocks needed, 596310 blocks free
error: not enough free disk space
lsblk shows this:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 931.5G 0 disk
├─sda1 8:1 0 512M 0 part /boot
├─sda2 8:2 0 40.8G 0 part /
└─sda4 8:4 0 890.3G 0 part /home
My downloaded packages are sent to /home/pkgcache, and emptying that folder did not help.
If 40GB is not enough for a root partition, can I just use parted?
Parted's print:
Number Start End Size File system Name Flags
1 1049kB 538MB 537MB fat32 boot, esp
2 538MB 44.3GB 43.8GB ext4
4 44.3GB 1000GB 956GB ext4 Linux /home linux-home
I would shrink the ext4 home partition, sda4, and move the now-available space to sda2.
SDA4 has over 300GB available. If stealing from it is the way to go, how much to take?
If 40GB should be enough space for a root partition - especially since pacman's packages don't land there - any suggestions on a likely spot to find files filling it up?

Also - when analyzing your disk usage, make sure to think in terms of "blocks", not GiB. Pacman takes into account blocksize when calculating the needed free "space". For example, a 100 files of only 1-byte size still take up 100 blocks.
