Public bug reported:
Description: Ubuntu 10.10
Release: 10.10
UEC suite : 2.0+bzr1241-0ubuntu4.1
Description :
After doing tests of custom EMI's instancitation, the Node Controller went
unstable. I was then unable to instanciate anymore instances. For the running
instances with EBS attached, I was then unable to detach them, and for new
instances, unable to attach a new EBS volume :
Detaching :
[Wed May 4 11:01:23 2011][020884][EUCAERROR ] ERROR: DetachVolume returned an
error
[Wed May 4 11:01:23 2011] ERROR: doDetachVolume() returned FAIL
Attaching :
[Wed May 4 09:26:04 2011][013319][EUCAERROR ] libvirt: internal error
'//,46.227.16.70,iqn.2009-06.com.eucalyptus.cluster1:store5,Itj/2Zbs1QNRlVzKROjF7k5nKBnck0NuFPlgm2hlf7F63sMKldO0W3vG4at6RE4PRe5gy6tKMPnkpZXAUQlymBOT+hAUmT4cBgvDYNdmAN98oLlUGXqkzZVI3SxBBfUeHwAi7v/tQHcZUg49ezVWpdXg4D55DUHT6BwsxLYmxXmbqRUH5RVeXw7r8Dhaplh1P5X5KWZHvdCrQDWbUF8zU37jxOsUANzzpTYUTfRl7VtHitvzQ2ebY06xRbABziBe6MY/p3r6qILyl8vDgot1MQ+OzWH3WizsDRu4g0uDWI3MVfKUh2UEz2mOA/IKSQF7Cfrv2zyIpUSGq+uDPhp/hg=='
does not exist (code=1)
In order to be able to instanciate, I manually restarted the iscsi part :
$ service open-iscsi restart
which cleaned all the running sessions, but lead to :
[Wed May 4 09:34:32 2011][013319][EUCAERROR ] libvirt: operation failed: disk
sde not found (code=9)
when I was trying to dettach disks.
Even by restarting all the services (NC, NC-publication, SC, SC-
publication), UEC wouldn't clean the missing volumes. UEC kept in memory
iscsi sessions and attachments (on the node controller (/dev/sdX and
when euca2ools-describe-volumes invoked, the volumes were still
present))
Expected behaviour :
- When all the components are restarted, the EBS sessions should be cleaned
What happened :
- Unable to get rid of "Attaching..." or "Dettaching..." status, due to missing
iscsi volumes
