Fix allocation code to allow replacement of single RAID 4/5/6 device.

The code fail to account for the case where we just need a single device
in a RAID 4/5/6 array.  There is no good way to tell the allocation functions
that we don't need parity devices when we are allocating just a single device.
So, I've used a bit of a hack.  If we are allocating an area_count that is <=
the parity count, then we can assume we are simply allocating a replacement
device (i.e. no need to include parity devices in the calculations).  This
should make sense in most cases.  If we need to allocate replacement devices
due to failure (or moving), we will never allocate more than the parity count;
or we would cause the array to become unusable.  If we are creating a new device,
we should always create more stripes than parity devices.

12 years agoFix possible NULL pointer dereferences when updating mirror log.

Fix possible NULL pointer dereferences when updating mirror log.

'_lv_update_log_type' takes a lvconvert_params argument so that it can pass
down the user's preference of 'region_size' and allocation_policy.  When
'mirror_remove_missing' was introduced (commit ID
95986e42a18ca98c9b1d777346978b7297c85558) it didn't make sense to pass down
user preferences - so NULL was given instead.  While it may never happen in
practice, static analysis reveals that this argument could be dereferenced.
So, if the user preferences were not passed in, glean the necessary fields
from what is already set in the LV.

Fix bug that caused RAID devices to be unable to activate if sub-LV was missing.

Commit 02f6f4902fd90709f55e2e97e969ee28c2945c81 introduced a bug that caused
RAID devices to fail to activate if the device for a single sub-LV failed.
The special case of LVM mirror was handled, but not LVM RAID.
