Hello,
We are attempting to move a hosted engine from an NFS to an iSCSI storage
domain, following the normal backup / restore procedure.
With a little intervention in the new hosted engine VM, everything seems to be
working with the new engine and the process gets to the point of trying to
create the new iSCSI hosted_storage domain. At this point, it fails with
"Storage domain cannot be reached. Please ensure it is accessible from the
host(s).”
The host itself does see the storage, and everything looks fine using iscsiadm
and multipath commands. However, if I look at the new hosted_storage domain in
the new engine, it’s stuck “unattached” and the “hosted-engine --deploy
--restore-from-file …” command loops at the "Please specify the storage you
would like to use” step.
Please see below for an excerpt of the output and logs, and let me know what
additional information I can provide.
Many thanks,
Devin
Here’s the output from the “hosted-engine --deploy --restore-from-file …”
command.
