[linux-lvm] lvextend problem

[Jens Berlips]

Hello

I have two partitions on a 80gb harddrive.

/dev/hdb1
/dev/hdb2

I have created a VG called store_vg.
$vgcreate store_vg /dev/hdb2
then
$lvcreate -lXXX -nstore_lv store_vg
creating an LV using all space left on hdb2

What I wanted to do next was adding the hdb1
without loosing the data on hdb2.

So I did.
vgextend store_vg /dev/hdb1
then
lvextend -lXXX /dev/store_vg/store_lv /dev/hdb1

But I noticed that this didnt work and when doing a
$ df. I got the same results as before. I guess this has
to do with hdb1 not being formatted (using mkfs.xfs) correctly. When
reformatting the entire LV (extended with hdb1) I got everything to work.
But all data lost.

This was more of a test, so I didn't loose any critical data. But how
should this proceedure be done correctly?

Thanks in advance
