Description of problem:

under some conditions, RHEL 8.6 anaconda refuse to recognize previous RHEL LVM LV volumes.

I tried simple layout (boot + lvm) at virtual machine and it works fine. but it failed with more complicated layout at physical machines.I remember years ago I met the same problem but it was fixed.

I tried to install RHEL 8.6 with mdadm+LVM (2 ssd + 6 harddisk). and when I reboot/reinstall, anaconda didn't recognize the previous result.
the same disk layout is recognized by RHEL 7.9 and 9.0.

I need to manauly create mdadm arrary to set correct chunk size. so it's a problem if anaconda can not recognize the current layout.
attach the screenshot of RHEL 7.9,8.6,9.0 and anaconda log for RHEL 8.6 and 9.0.
