Hi,


please send us the following information:


$ onedatastore show -x <lvm_datastore_id>
$ oneimage show -x <image_id> (after creating the image and before deleting it)
$ cat /var/lib/one/remotes/datastore/lvm/lvm.conf


cheers,
Jaime

Hi everyone,I have found several problems when I use LVM datastore on OpenNebula3.8. 
First,when I delete the image which is registed in the LVM datastore, OpenNebula doesn't remove the lv.
Following is error record written in the oned.log:
