Fix /proc/drbd parsing in presence of gaps

In case there are gaps in /proc/drbd related to the minors sequence,

we currently fail to parse the file correctly.

The patch fixes this by skipping empty lines in...

Convert ldisk_degraded to tri-state value

This allows us to report “uncertain” states (LDS_UNKNOWN) for cases

Use full-stripe size in LVM growth

LVM has issues when growing stripped volumes, so it's best to specify
the growth in exact multiples of the full stripe size (as precise as
possible). For this we need to do a couple of changes:
- in LVM Attach(), we query additionally the VG extent size and the LV...

Assemble DRBD using the known size

This patch changes DRBD disk attachment to force the wanted size, as opposed to
letting the device auto-discover its size.

This should make the disks more resilient with regard to small differences in
