Right, that's my problem.

reassemble the array on boot.

Red Hat Bugzilla ? Bug 1451660

That's probably a mistake.? The bug isn't closed.

One of the suggested work-arounds in that bug report is to revert to an 
older version of dracut and rebuild your initrd.? You'd need to get:

dracut-033-535.el7.x86_64.rpm 
dracut-config-rescue-033-535.el7.x86_64.rpm 
dracut-network-033-535.el7.x86_64.rpm kexec-tools-2.0.15-13.el7.x86_64.rpm

...from the vault: http://vault.centos.org/7.5.1804/updates/x86_64/Packages/

Downgrade those packages, and then run "dracut -f" to rebuild the
initrd
for your kernel.

Hello?everybody!
I have good news, the problem is gone.

For everyone who has this problem, I did the following

I use rpm...

Get list of installed packages
# rpm -qa | grep "dracut"
dracut-033-554.el7.x86_64
dracut-network-033-554.el7.x86_64
dracut-config-rescue-033-554.el7.x86_64

Delete packages

# rpm -e --nodeps "dracut-config-rescue-033-554.el7.x86_64"
# rpm -e --nodeps "dracut-network-033-554.el7.x86_64"
# rpm -e --nodeps "dracut-033-554.el7.x86_64"
?I download old packages in local directory and install it
# rpm -ivh dracut-033-535.el7_5.1.x86_64.rpm
Preparation... ################################# [100%]
Update / install...
1:dracut-033-535.el7_5.1 ################################# [100%]
# rpm -ivh dracut-config-rescue-033-535.el7_5.1.x86_64.rpm

Preparation... ################################# [100%]
Update / install...
1:dracut-network-033-535.el7_5.1 ################################# [100%]

check installed...
# rpm -qa | grep "dracut"
dracut-033-535.el7_5.1.x86_64
dracut-network-033-535.el7_5.1.x86_64
dracut-config-rescue-033-535.el7_5.1.x86_64
After that, the system successfully booted with one disk disabled. The array?
was assembled at one disk . After connecting and booting with two attached disks
manually add? disconnected partitions array.?
?
# mdadm /dev/md124 --add /dev/sda1
mdadm: hot added /dev/sda1
# mdadm /dev/md125 --add /dev/sda2
mdadm: hot added /dev/sda2
# mdadm /dev/md126 --add /dev/sda3
mdadm: re-added /dev/sda3
# mdadm /dev/md127 --add /dev/sda4
mdadm: re-added /dev/sda4

And waiting for the end of the recovery process for all arrays
# cat /proc/mdstat

Thanks for your quick help!
