Subject: [PATCH 1/2] Exclude unusable disks from PartitionFactory
|
|
|
585101 |
|
|
|
585101 |
We already remove disks that are too small or not partitionable
|
|
|
585101 |
in the PartitionSetFactory which allows us to create partitions
|
|
|
585101 |
on multipath devices where Anaconda tells us to use both the mpath
|
|
|
585101 |
device and the backing disks, we should do the same for the
|
|
|
585101 |
PartitionFactory.
|
|
|
585101 |
|
|
