6391d03f54 Fix backward compatibility for major:minor query. 
Is an application uses query and set major:minor
to device, it should not fallback to default major by default.

Add new function whoich allows that (and use it in lvm2).

c1fdeec999 Fix readahead calculation problems. 
During vgreduce is failed mirror image replaced with error segment,
this segmant type has always area_count == 0.
Current code expects that there is at least one area with device,
patch fixes it by additional check (fixes segfault during vgreduce).

Also do not calculate readahead in every lv_info call, we only need
to cache PV readahead before activation calls which locks memory.

ca51e5d9ec Remove /dev/vgname/lvname symlink automatically if LV is no longer visible. 2009-05-28 01:11:29 +00:00

d396100278 Use readahead of underlying device and not default (smaller) one. 
When we are stacking LV over device, which has for some reason
increased read_ahead (e.g. MD RAID), the read_ahead hint
for libdevmapper is wrong (it is zero).

If the calculated read_ahead hint is zero, patch uses read_ahead of underlying device
(if first segment is PV) when setting DM_READ_AHEAD_MINIMUM_FLAG.

Because we are using dev-cache, it also store this value to cache for future use
(if several LVs are over one PV, BLKRAGET is called only once for underlying device.)

This should fix all the reamining problems with readahead mismatch reported
for DM over MD configurations (and similar cases).

eb91c4eee3 Use suspend with flush when device size was changed during table preload. 
This allows online mirror resize, also removes condition to preventing
code to do this.

0c8bdaf33c Fail add tree node when requested major/minor is used. 
Check for major/minor collision is added in _add_dev_to_dtree()
where we already read info by uuid,
so in the case of requesting major/minor it queries device-mapper
by major/minor for device availability.
