[ovirt-users] move disk and lv not removed

Tue Oct 24 05:29:28 UTC 2017

Hi Gianluca,

Can you try to reproduce it with FC? Maybe it's somehow related to that.
Did you try to lvremove the old lv's, or are they still in use?
Trying to do this from the SPM should be ok. What do you mean synchronize
the information at the other node side?
In any case, this is a disk that you don't need anymore, isn't it? You said
that the copy part of the move operation went well.

Regards,
Idan
