@RL_Dane I'm doing the hokey pokey with partitions on an HDD tonight and I feel your pain, the system is completely bogged down under heavy I/O load.
Requirement is to grant an external host access to an HDD which holds various large files. It's fairly full at 8TB and the files are in the hundreds-of-megabytes range. Problem is, it's been formatted ext4 all its life and the external host speaks only NTFS and can't be taught anything else (pretty locked down system). So the workflow is:
Shrink the ext4 partition to leave as much free space as possible trailing it
Grow the NTFS partition to fill the free space
Copy as many files as will fit in the expanded partition
Verify copy integrity
Delete copied files from the ext4 partition to free up space
Repeat
"You put some NTFS in, you take some ext4 out, you copy some files over and you shake em all about"
Luckily my largest file is smaller than the available free space so it's *possible* at least, it just takes ages and makes everything run like molasses
@tek_dmn no, the other host is some embedded thing which might be Linux-based, actually (there's a copy of the GPL in the printed manual, but no indication what it applies to). It can read files as a USB host, but not as a network client. Even so, per manufacturer support, it can only read NTFS and FAT.
It probably would've been worth buying another external disk so I could just copy everything once and be done with it, but it seems like a waste to buy a whole 'nother 8TB to only use it one time.

Ahh, I know this torment as well.
It's the great grandchild of trying to do anything with an early Classic Mac with only one floppy drive and no HDD.
@khird @RL_Dane Okay, the other host is Windows.
Samba? Would have been easier to set it up ad-hoc to export a share than to do the reformatting hokey-pokey.
