Hai Bernd Bausch,
Thanks for your help.
As you said , I am not completely familiar with all the underlying
concepts. But I am trying to learn thanks for pointing me in the right
direction.
Now, I have achieved what I wanted. I have followed your second suggestion
with some more reading in to LVM
Maybe I should point out more clearly that there are several ways of
providing disk space for your instances.
If you choose file based storage for your instances (e.g. ephemeral
disks as qcow images), you'll need a lot of space in
/var/lib/nova/instances as ephemeral storage. If you delete
Your node uses logical volume /h020--vg-root/ as its root filesystem.
This logical volume has a size of 370GB:
# lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
NAME FSTYPE SIZE MOUNTPOINT LABEL
(...)
└─sdk5 LVM2_member 371.5G
* ├─h020--vg-root ext4 370.6G /
Hai Eugen,
Thanks for your suggestions and I went back to find more about adding the
new HD to VG. I think it was successful. (Logs are at the end of the mail)
Followed this link -

But still on the nova-compute log
Okay, I'm really not sure if I understand your setup correctly.
Server does not add them automatically, I tried to mount them. I tried they
way they discussed in the page with /dev/sdb only. Other hard disks I have
mounted them my self. Yes I can see them in lsblk output as below
What do you m
Hai,
Thanks for a quick response.
- what do you mean by "disks are not added"? Does the server recognize
them? Do you see them in the output of "lsblk"?

Hi,
there are a couple of questions rising up:
- what do you mean by "disks are not added"? Does the server recognize
them? Do you see them in the output of "lsblk"?
- Do you already have existing physical volumes for cinder (assuming
you deployed cinder with lvm as in the provided link)?
