Subject: [PATCH 32/32] libparted: device mapper uses 512b sectors (#1188431)
|
|
|
9e7f5d |
|
|
|
9e7f5d |
device mapper doesn't use the device's sector size when creating a
|
|
|
9e7f5d |
table. It always uses 512b units. This causes partitions to be created
|
|
|
9e7f5d |
8x smaller than expected on devices with 4906b sectors.
|
|
|
9e7f5d |
|
|
|

Resolves: rhbz#1188431
