Alter distkey for a table with 22 Billions rows never ends

Question

I have a table with 22560627453 rows, with Even diststyle. The sortkey is date

I'm trying to run

ALTER TABLE movements 
    ALTER DISTSTYLE KEY DISTKEY id;

but this never ends. In fact, the cluster is at 75% of disk usage 4,5 TB/ 6TB and when running this alter the disk usage reaches 100% and doesn't end.

I tried creating a new table with the correct distkey and sortkey and then insert from the old one to the new one, but happens the same it reaches 100% of disk usage.

The total table size is 768327 (blocks of 1mb) so its 770 GB, then I don't understand why it reaches 100%. Because despite copying the table it should be around 700 gb free.

All table statistics have been achieved using:

select *
from svv_table_info
where "table" = 'movements';

How can I alter the distkey without reaching 100%. Is there a trick, or a tip to do it faster?

Old developers didn't care about distkeys and big part of the is using EVEN...
