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

# rpm -ivh dracut-network-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!
Best Regards
