Of course if you need to troubshoot the system, and the vm is not
running, there is no problem to access the lv directly.
Even then, you should *not* activate all lvs in a vg using
vgchange -a y
But activate only the lv you want to access using
lvchange -a y
Thank you, did not know

You mean you activate the lv on the host?

This not the output of lvs, these are the symlinks to the active lvs.
Can you share the lvs output before and after the vm is stopped?
No, since the vm does not start!

I'm not sure what you mean. Can you share the output of lvdisplay before
and after the operation?
Already is not present, I have removed this problem disk

Did you update lvm cache using "pvscan --cache"?
No. I should after each operation with disks, do in the console "pvscan -
cache"?

What do you mean by that?
This is first problem! Second problem - don't start the vm.

Is the volume preallocated or thin provisioned?
All my disks - prelocated.
Preallocated volumes are extended when you modify the volume size in
engine ui (as you described). Thin provisioned volumes are extended
only when the available space is bellow a threshold, so the lv
size will not change after you modify the volume size.

Do you mean that now everything works?
The VM it has been removed, since for a week I could not start it!
Now all works on others VM. But there were 2 problems! My problem to
understand, that I have made not so or it is a problem oVirt.
I wish to use oVirt, but is not assured of it because of these problems!
