I have 2 disks, sda (which is SSD with ~110GiB) and sdb (an HDD with ~930GiB). My sdb disk used to be partitioned into 2 parts for dual booting reasons, but I have completely migrated to Arch since then and removed sdb2 and resized sdb1 into the full disk. I did the resizing from the live usb, and sdb1 is where my home partition is. I was expecting home partition to break, but it works perfectly fine. I didn't need to re-generate fstab or anything like that for the system to boot or to access my personal files. However, when I open dolphin, it strangely tells me sdb1 has the old size. However, the output of lsblk is as expected:
[felipe@H87M-D3H ~] lsblk -l
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 111,8G 0 disk
sda1 8:1 0 512M 0 part /efi
sda2 8:2 0 109,3G 0 part /
sda3 8:3 0 2G 0 part [SWAP]
sdb 8:16 0 931,5G 0 disk
sdb1 8:17 0 931,5G 0 part /home
sr0 11:0 1 1024M 0 rom This is my dolphin screen cap: https://imgur.com/a/3RBsYmZ
I checked df -h and the output is consistent with dolphin instead of lsblk:
Filesystem Size Used Avail Use% Mounted on
dev 3,9G 0 3,9G 0% /dev
run 3,9G 1,3M 3,9G 1% /run
/dev/sda2 110G 14G 96G 13% /
tmpfs 3,9G 429M 3,5G 11% /dev/shm
tmpfs 3,9G 0 3,9G 0% /sys/fs/cgroup
tmpfs 3,9G 80K 3,9G 1% /tmp
/dev/sda1 511M 280K 511M 1% /efi
/dev/sdb1 485G 193G 268G 42% /home
tmpfs 789M 12K 789M 1% /run/user/1000Is there something I should have done after resizing the partition? It works just fine, however I'm afraid that something could go wrong if I extrapolate the free space, like it overrides existing files or just tells me I don't have space when I actually do.

Nevermind this post, I solved it with a little research. Appearently, I didn't know I should resize the file system after resizing a partition - I thought they were resized together. I used cfdisk to resize, so I was clearly wrong - AFAIK (c)fdisk only handles partitions.
I fixed it by running:
# resize2fs /dev/sdb1Offline
