I had to recently go from a 10TB to an 18TB. Cloning process took forever, but now works perfectly.
However, when the inevitable time comes, and the drive is eventually full (hopefully that takes a long time) I am unsure what steps to take then.
Currently the max hard drive space, commercially available (unless I am mistaken) is 22TB, I did see a post online stating 24TB is available but don’t know when, and just guessing, it will be super expensive.
I know the thought of going from 10TB to 18TB was amazing, (Yay free 8TB, that will keep me going for awhile) but then it won’t and I’ll have to do this all over again, but my options will (at least currently be) 20TB, 22TB or 24TB, which only provides another 2-4-6TB free.
Is it possible to link an existing drive, to another one? or anything like that.
If you’re not going to get into proper raid/zfs storage pool type solutions, you could potential use lvm to span drives. You don’t mention what platform you’re doing this on.
