It is as if
they were assigned the same UUID *because* they were in a raid. [snip]
That is normal for linux raid. Here is a sample of an MD raid1:
blkid | grep -E "sda1|sdb1|md1"
/dev/sdb1: UUID="deb9b913-0a73-90d8-6b37-12e5156fce03"
UUID_SUB="50b1ecf9-a7bd-6ba5-131e-4bbde91735c8"
LABEL="wombat.wombatz.com:boot" TYPE="linux_raid_member"
PARTUUID="28f4447c-01"
/dev/sda1: UUID="deb9b913-0a73-90d8-6b37-12e5156fce03"
UUID_SUB="8efb2a67-f08a-4ba9-186f-11f7afec25c7"
LABEL="wombat.wombatz.com:boot" TYPE="linux_raid_member"
PARTUUID="87e58b90-01"
/dev/md1: UUID="72f36fca-b84e-45f4-8621-d85b14a32ff3"
BLOCK_SIZE="4096" TYPE="ext4"
Note that the "UUID" is the same, but they can be differentiated by the
"UUID_SUB".
