[Bug 590929] Re: eucalyptus create and delete volumes sometimes fail on lvm commands

[Neil Soman]

Against 1.6.2, I tried a test which involved creating and deleting 50
volumes in a tight loop, which passed successfully. With 100 volumes, I
was able to trigger a failure to clean up volumes. In addition, once the
max volume limit is reached and exceeded, occasionally, volumes are not
cleaned up properly. I have seen the "Volume: Error while communicating
with Storage Controller: CreateStorageVolume:Internal Error." message on
occasion, when this happens.

None of these issues can be reproduced against 2.0. Version 2.0 has a
number of fixes that have to deal with failure recovery and CLC/SC
communication that helps scale. At this point, backporting these to
1.6.2 does not make a lot of sense (they are non trivial), since 2.0
will be released shortly, but the upstream is willing to discuss a
possible backport effort if this is critical and upgrading to 2.0 is not
an option.
