[Xen-users] Detach specific partition LVM of XEN

["Souza Anderson" <souzalix@xxxxxxxxx>]

Hi...

 

I have had a problem when I am going to detach one specific LVM partitions of Xen, so I have been trying xm destroy <domain>, lvchange -an <lvm_partition>, lvremove -f.... So I haven't had sucess. I restarted the server with init 1 yet and nothing... I have seem two specific process started xenwatch and xenbus, but I am not sure if this processes have some action over LVM partitions + XEN. 

I need to know how can I remove this partition to build another xen VM, an if  I need to stop the xend and xendomais services to do the detachment.

 

Thanks so much!!!!
