Checked with my ASCII installation on the same PC. Had to update Veracrypt to run the same version first. There I do not see the shutdown delay I have with Beowulf. Something is different here.

Not sure how to make encryption faster on veracrypt for your specific use sorry rolfie. My experience is with lower physical drive space of a 64 GB usb that i use to backup docs that is encrypted with aes/serpent using a password and key file, unmounting usually takes around 3 - 5 seconds. Maybe you need some kind of enhanced entropy solution for the amount of space you are encrypting, maybe haveged or rng-tools?

If Caja is correct, 1.7TB. About half of a 4T drive.

Seems you have a lot going on there, the wait time is probably good only being 15 seconds, how big is the space veracrypt is dealing with ?

Beowulf amd64, openrc as init, shares from file server mounted with nfs4. Veracrypt is used to open a NTFS container as data drive for a Win7 VM. This is done via a script in the user startup folder.

Shutting down this container seems to cause a about 15s long delay past the line "Asking all remaining processes to terminate".

The complete output looks like this:

[ok] Asking all remaining processes to terminate ... done.
Currently running processes (pstree):
init-+-rc---openrc---openrc-run---sendsigs---pstree
     |-rpc.statd
     |-rpcbind
     |-veracrypt---dmsetup
     '-veracrypt---18*[{veracrypt}]
[FAIL] Killing all remaining processes ... failed

On another PC with a similar setup, just without Veracrypt, the shutdown has normal speed.

How can I speedup closing the Veracrypt volume?
