Hi,

That bug seems to be private :(

I'm interested also to hear about this feature, as with 3.3.2 I had my gluster vms go into paused state quite a few times and they actually couldn't be resumed at all, they needed to be forced off and back on.

interesting... :) so this is now configurable...
what happens if qemu fails to start the vm (this happens sometimes - mostly on file type storage). do we have a re-try or a specific error telling the use that the activation failed and manual intervention is required?

1.hosted-engine --vm-start should start engine vm. There was no problem with it when I tested it.
2.hosted-engine --vm-start-paused was added for the case when something is wrong with engine vm and it can't start and requires user intervention. For example in case of kernel panic.
User can start engine vm in paused mode ,connect to it and try to fix the problem by booting in single user mode ,etc.
3.When the connectivity to shared storage is lost engine vm becomes paused. VM should be automatically unpaused after connectivity resumes (we introduced this feature in 3.3) but in case of NFS it could take quite time.so may be we should add something like --vm-resume in order to resume
Are we talking only on the hosted engine vm or all other vm's? if I have
other vm's they will also stop, will they be auto started as well?
the engine vm manually.

Thanks,
Leonid.

It was paused due to the connection loss to the NFS server, I would assume
once the connection is restored it could attempt to restore it? But I can
try dig up the vdsm logs if you want, they would only be a few hours old

I think having an option like --vm-resume would at least hide the reason of
having to dig into virsh and messing with authentication at the very least.

the question is what was the vm paused on... this can be found in the qemu
vm log.
if the vm is paused it will not be auto started - so I am not sure what
you expect to change? virsh requires authentication regardless to hosted
engine :)
Leonid, did you do any testing there?

I have opened this BZ 1055461 anyway just in case

      I was more interested in how the score process would be

      I left it for a few minutes and nothing seemed to have changed, I
      think it relates to hosted engine as virsh requires
      authentication. Should I still open a bz?

          I am not sure this is a hosted engine question as much as a
          qemu question.
          qemu-kvm will not support auto start of vm's after EIO because
          of remote possibility of corruption.

              Hi,

              Quick question, in the scenario eg. the NFS server becomes
              unreachable and the hosted-engine goes into a paused
              state. Will other hosts attempt to bring it back up?
              Should there be a command eg.  hosted-engine --vm-resume ?

              When this happened, I manually forced it to resume using virsh

                              Hi,

                              With the great help from sbonazzo, I
              managed to step
                              past the initial bug with the
              hosted-engine-setup but
                              appear to have run into another show stopper.

                              I ran through the install process
              successfully up to
                              the stage where it completed and the
              engine VM was to
                              be shutdown. (The engine has already been
              installed on
                              the VM and the host has been connected to
              the engine).

                              The issue starts here that the host finds
              itself not
                              able to start the VM up again.

                              VDSM Logs:
              http://www.fpaste.org/69592/00427141/
                              ovirt-hosted-engine-ha agent.log
              http://www.fpaste.org/69595/43609139/

                              It seems to keep failing to start the VM..
              when I
                              restart the agent I can see the score drop
              to 0 after
                              3 boot attempts.  The interesting thing
              seems to be in
                              the VDSM Logs "'Virtual machine does not
              exist',
                              'code': 1}}"

                              I'm not sure where else to look. Suggestions?

                              Cheers,

                              Andrew
