Previous setup: Oracle Linux 7.9, RAID1 with 2 SSDs.
Current setup: Oracle Linux 9.4 installation, only one SSD detected as a partition.
Attempted to use the documentation link provided (https://docs.oracle.com/en/learn/ol-mdadm/index.html#create-a-raid-device).
‘lsblk’ shows all partitions.
I previously set up a RAID1 on Oracle Linux 7.9 using this Oracle documentation (https://docs.oracle.com/en/learn/ol-mdadm/index.html#create-a-raid-device), specifically the “Create a RAID Device” section, I set up a RAID1 array using two SSDs. Now, I have installed Oracle Linux 9.4 on the host, and during the installation, it only detects one of the two SSDs as a single partition, instead of recognizing them separately.
How can I resolve this issue without wiping the drives? Why did this happen? I created a standard RAID1 without using the “spareDevice” function. Running lsblk shows all the partitions.
