Hi there,

I am dealing with this issue for a while, but could not figure out what is
going on.

After a reboot in the openstack server, I am not able to restart ANY
instance that had a nova-volume attached.
I tried the DR procedure here without any improvement:
http://docs.openstack.org/trunk/openstack-compute/admin/content/nova-disaster-recovery-process.html

The error in compute.log is:
ERROR nova.compute.manager [req-adacca25-ede8-4c6d-be92-9e8bd8578469
cb302c58bb4245cebc61e132c79c1111 768bd68a0ac149eb8e300665eb3d3950]
[instance: 3cd109e4-addf-4aa8-bf66-b69df6573cea] Cannot reboot instance:
iSCSI device not found at
/dev/disk/by-path/ip-10.100.200.120:3260-iscsi-iqn.2010-10.org.openstack:volume-20db45cc-c97f-4589-9c9f-ed283b0bc16e-lun-1

This is a very restrictive issue, because I can not simply attach volumes
to instances knowing that in a power failure or reboot for maintenance I
will have my instances unavailable.

Below there is some info about my setup.
Any idea? Anything!
:)
