This is for defect https://bugzilla.redhat.com/show_bug.cgi?id=761278 This is for a system that is connected to a SAS (Serial Attached SCSI) multipath array. When I choose "Use All Space" and verify that "Use LVM" is enabled, I see 2 drives available. When I pick the first drive to install on, I get the following failure message: "Error Partitioning Could not find enough free space for automatic partitioning, please use another partition method." --- pyanaconda/storage/devicetree.py | 12 ++++++++++++ 1 files changed, 12 insertions(+), 0 deletions(-) diff --git a/pyanaconda/storage/devicetree.py b/pyanaconda/storage/devicetree.py index 7b411e6..f545ba8 100644 --- a/pyanaconda/storage/devicetree.py +++ b/pyanaconda/storage/devicetree.py @@ -1876,6 +1876,18 @@ class DeviceTree(object): [d['name'] for d in self.topology.devices_iter()]) old_devices = {} for dev in self.topology.devices_iter(): + # 761278 + # The basic problem is that the code in the devicetree to handle scanning and + # activating multipath devices does not work if the mpaths are already active + # when the devicetree scans the system.
