At the moment i'm not able to create a VM. The logs:

Changing TM_MAD to lvm instead of shared i got this error:

It tells me that lv-one-4 isnt active but it is on both nodes:

lv-one-4 vg-one -wi-a---   8,00g


Any ideas? i followed the documenation of LVM but there are no hints to solve this problem.



Best regards,
Tobias
