Comment 2 for bug 517086

On Lucid, I don't get the Volume: Error communicating with Storage Controller: CreateStorageVolume:Internal Error. error anymore. However, not all volume groups are deleted:

$ sudo lvscan
  ACTIVE '/dev/vg-wsdyiQ../lv-K0hXfA..' [1.00 GiB] inherit
$ sudo vgscan
  Reading all physical volumes. This may take a while...
  Found volume group "vg-wsdyiQ.." using metadata type lvm2

Note that at times a volume is stuck in the 'creating' stage. It can be deleted via euca-delete-volume, but deletion does not seem to be complete.

The situation seems to get worse when doing the create/delete volume more often:

$ for i in $(seq 1 32); do euca-create-volume -s 1 -z torsten; done
$ euca-describe-volumes | grep avail | wc -l
29
$ euca-describe-volumes | grep creat | wc -l
3
$ for i in $(euca-describe-volumes | cut -c8-20 | xargs); do euca-delete-volume $i; done

$ for i in $(seq 1 32); do euca-create-volume -s 1 -z torsten; done
$ euca-describe-volumes | grep avail | wc -l
26
$ euca-describe-volumes | grep creat | wc -l
6
$ for i in $(euca-describe-volumes | cut -c8-20 | xargs); do euca-delete-volume $i; done

$ for i in $(seq 1 32); do euca-create-volume -s 1 -z torsten; done
$ euca-describe-volumes | grep avail | wc -l
24
$ euca-describe-volumes | grep creat | wc -l

$ for i in $(euca-describe-volumes | cut -c8-20 | xargs); do euca-delete-volume $i; done
