I have  removed  disks  from  linux  software arrays dozens of times (a lot
of this was with testing) and even hot added new ones  back never loosing
any data or having any difficulty at all getting the array back up. If you
need help with that please post the error messages and exactly what commands
you have tried.

After that I built new array, with --force, (I noticed, that mdadm

This is not by default but it can if you specify so. I mean if you say 4
disks and add 3 drives + 1 missing it will add a failed drive.
