Red Hat Bugzilla – Bug 974703
Installation process detaches part of Software RAID array when installing from USB drive
Last modified: 2013-06-15 06:25:13 EDT
Description of problem:
sda - 512GB SSD (new, replaced older 128GB)
sdb - 1TB HDD, part of raid array
sdc - 1TB HDD, part of raid array
sdd - 1TB HDD, part of raid array
sde - 1TB HDD, part of raid array
During installation (from USB drive) disk utility mounts:
usb drive as sda
sda as sdb
and so on...
after installation is completed, when I've checked my raid array, it displayed "DEGRADED" and sdb drive was detached from the array.
Version-Release number of selected component (if applicable):
Fedora-19BETA installation dvd
Tried two times, same issue happened
Steps to Reproduce:
1. Start fresh installation on system with software raid array attached
2. Go to partitioning
installation drive shows up as /dev/sda... while it shouldn't be there
installation usb drive not to shop up on the available devices list

What you have is an mdarray comprised of a partition on each of sdb,sdc,sdd,sde named Stefan:3.
What you did during disk selection was de-select sdb,sdc,sdd,sde, which means your raid array will not be visible since you've excluded the disks it resides on from the installation.
The only disk modified in any way by the installer is sda (your SSD) since it is the only disk you selected to be used during installation. It does not appear to be the source of the installation media.
It looks to me like sdf is the source for the installation media. Did it appear in the disk list?
Actually, it's my fault - I've just attempted to recreate the process.
I've used CentOS CD to partition the SSD before installation with usb drive attached - this is where my disk got detached.
Sorry for the bug report, my fault, should have not installed os late in the night :)
