Issue

• Using the following partitioning information for installation, but the installer fails while checking storage.

bootloader --location=mbr --driveorder=sda,sdb --append="crashkernel=auto rhgb quiet"
clearpart --drives=sda,sdb --all --initlabel
part raid.01 --size 500 --asprimary --ondrive=sda
