I've performed a full re-installation of the frontend as requested.
Before any tests or registration, I've updated all eucalyptus packages to
1.6.2-0ubuntu30.4.
I've also adjusted cluster1.storage.maxtotalvolumesizeingb in the web front end
(set to 250).
I did 10 test loops (as usual creating 40 volumes).
+ No Internal Errors were reported.
+ Space available and # of volumes correctly reported in sc-stats.log
+ Deletion worked perfectly
But I found one (just one) failure reported by euca-describe-volumes, 10
seconds after the creation loop :
VOLUME vol-526005D5 1 cluster1 failed
2010-09-15T17:00:32.7Z
A few seconds later, euca-describe-volumes didn't report anything about
this failure, weird. But I had only 39 volumes created.
This is what was reported in cloud-error.log:
