Hi, So if I were to want to stop the resync process on a very large array (1.4T), since it is in the middle of the day and makes work slower... How can I tell which drive is the one that is being used to check all the rest of the data? Or in other words, how can I stop the resync process and let it cont. later?

The data is distributed over all of the drives. There are also 'parity' blocks used for coping with missing devices. This 'resync' process is checking that the parity blocks are all correct and will correct any that are wrong.
