I have GPT partitioning for my drive:
$ sudo fdisk -l /dev/sda
Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

$ mount | grep /dev/sda
/dev/sda2 on / type ext4 (rw,relatime,errors=remount-ro,data=ordered)
/dev/sda4 on /home type ext4 (rw,relatime,data=ordered)
$ lsblk

The sda5 partition was meant to be /media/DATA partition, but I changed my mind, and I am using the /home to store my data. But, the /home is almost full, now.
How can I grow (+100GB) mounted /home partition without loss of data?

I haven't used fdisk in a long time. I use gdisk, and with gdisk you can delete /dev/sda5, and then delete /dev/sda4, and then create sda4 again with same beginning offset (be careful) as before, but with size set to what you want it to be. Once that's done, save, and exit. You may be required to run partprobe (from parted) to refresh the /proc/partitions. Once /proc/partitions is refreshed with updated size of /dev/sda4, and /dev/sda5 gone, then run resize2fs /dev/sda4 to resize it. Also in fdisk before making any changes, make sure to set display units to sectors (using u command).

Do you know whether size changes (orpartprobeupdates in general) affect mounted partitions?

the best to affect in-use partitions is to run partx: after having done the gdisk voodoo,partx -u /dev/sda4would update it (perhaps partx -d /dev/sda5 would be needed no idea)., it can be checked by looking at the content of/sys/class/block/sda4/sizebefore and after partx

@HaukeLaging --- IIRC, devices in use/mounted will not see these changes.
