Is there a way, I can delete everything in cloudstack at once and start afresh?

I was just trying to delete the primary storage but management UI shows me an error message showing me the following Cannot delete image store with active templates backup! Please note that I have deleted all the instances that were using storage. Furthermore, I was working to set up new primary and secondary storage on kvm host. I did directory setup and put the right info in /etc/hosts file but I was unable to download the system vm template using following command /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt \ -m /secondary \ -u http://cloudstack.apt-get.eu/systemvm/4.6/systemvm64template-4.6.0-kvm.qcow2.bz2 \ -h kvm -F The reason of failure, obviously, is that I don't have mysql on hypervisor machine How can I resolve these problems?

It could be you use autofs for your home folder? Either way the error is fairly standard – the file system thinks you have a file open on the NFS share, it therefore doesn’t allow you to unmount it cleanly, leading to the shutdown hang. To troubleshoot just do a “mount” and see what share/folder is mounted to your NFS server. If this was on your KVM host it would make more sense – since you will be using NFS for your secondary storage the KVM host will have this mounted at some point, and it may not unmount this cleanly if it thinks there are still files in use. If so you need to shut down the KVM cloudstack agent and libvirt before unmounting the share.

When I try to shut down this machine, it hangs. It fails to stop the cloudstack-management but it surpasses this point. Furthermore, during shutdown, machine hangs with this message Unmounting NFS filesystem: unmount.nfs: /mnt/some-long-uuid: device is busy After showing above message, it hangs and I have to power off the system. How can I get around this problem. Regards Adeel dag.sonst...@shapeblue.com www.shapeblue.com<http://www.shapeblue.com> 53 Chandos Place, Covent Garden, London WC2N 4HSUK @shapeblue
