The md filter can operate in two native modes: - normal: reads only the start of each device - full: reads both the start and end of each device md 1.0 devices place the superblock at the end of the device, so components of this version will only be identified and excluded when lvm uses the full md filter. Previously, the full md filter was only used in commands that could write to the device. Now, the full md filter is also applied when there is an md 1.0 device present on the system. This means the 'pvs' command can avoid displaying md 1.0 components (at the cost of doubling the i/o to every device on the system.) (The md filter can operate in a third mode, using udev, but this is disabled by default because there have been problems with reliability of the info returned from udev.) |
