Fail migration from CentOS 8 to Rocky on baremetal

[zykov-as]

I try migrate from CentOS 8.5.2111 to Rocky 8. CentOS installed on bare metal server and disks added from storage with multipath. When I try run migration script, I get error

./migrate2rocky.sh: line 562: dm-2/partition: No such file or directory

Unable to gather EFI data: Can't find disk name or partition number for dm-2.

An error occurred while we were attempting to convert your system to Rocky Linux. Your system may be unstable. Script will now exit to prevent possible damage.

my disks:

What can I do for run this script?

[lilocruz]

It seems that the script is trying to access a partition on dm-2, which it cannot find. Probably the script expects a certain disk layout, or it might not be fully compatible with multipath devices. But I would suggest you check your multipath.conf for any misconfigurations or any issues, as the output you've provided indicates a duplicate keyword warning. You can also verify the disk and partition layout to make sure the EFI partition is present and correctly identified by the system. You can use lsblk or blkid for this.

Hello there'

I'm under impression I have very similar issue
