Hi,
I'm running the 3.14 kernel with lvm 2.02.98 and I ran into something unexpected
with lvresize.
I created a sparse volume:
lvcreate -L 25M -V 50M -n sparsevol myvg
This gives output in lvdisplay like this:
LV Size 52.00 MiB
Current LE 13
COW-table size 28.00 MiB
COW-table LE 7
I then resized the volume with lvresize:
lvresize -L 200M myvg/sparsevol
This seems to resize the COW-table, but not the volume itself. Now lvdisplay shows:
LV Size 52.00 MiB
Current LE 13
COW-table size 200.00 MiB
COW-table LE 50
At this point I've got 200MiB of backing store and running "lvs" shows an LSize
of "200m" but I can only write 52MiB worth of data to the volume before it
complains.
Is there a way to expand the "LV Size" shown in lvdisplay so that I can write
the resized amount of data to the volume?
Thanks,
Chris
