I understand the '-o remount', not the '-rw'.

Assuming an ugly typo.

I think: That is strange.
And wonder: Why was /home not mounted?

Assuming something as "home was and is 400G"

Acknowledge
NOTE: Only the logical volume was resized. [1]

Think "have shot my self in the foot", "learnt much today".
Even on slow hardware is ten hour response time an indicator for
"something is wrong".
My guess is root filesystem mounted readonly being the culprit.

Oh, that is cheap. I do read it as:
You must spend time on my problem and report back to me!
Do not expect any follow-up from me, I have already said "Thanks"!!!
Input for follow-up:
* Powercycle the system.
* Continue with reaching the intended goal
* complete resizing of /home [1]
* resize / [1]

[1] Be aware of the command `resize2fs` and the flag `--resizefs` for
the command `lvresize`.
