I have a vg (data) with four drives /dev/sd[b-e]1
I created a 2 stripes lv (data1) with sd[bc]1
Now I want to add the remaining two drives to the lv, but lvextend
complains about missing pes! I tried also with a very small number of
pes - without success:
lvextend -l +400 /dev/data/data1 /dev/sde1 /dev/sdd1
lvextend -- extending logical volume "/dev/data/data1" to 35.45 GB
lvextend -- not enough free/allocatable physical extents to extend
logical volume "/dev/data/data1"
It returns error code 12:
12 error setting up VGDA for logical volume extension
which is not very useful in this case.
Any idea?
kind regards,
Rainer
