In addition, I do not like the execution of the SQL statements in the script. There is a SP called DeleteVds(v_vds_id UUID) and you should use that since it encapsulates all details. For example, your script does not handle permission clean-up as the SP does and therefore leaves garbage in the database. In addition, a failure in your script may leave database in inconsistent state while the SP is executed in one transaction and will leave DB consistent. So, in short I would prefer in this case that the relevant SP will do the clean-up since this is the one that is used by the code and that insures (at least I hope so) , that all related entities are removed as well. > > Thanks > > -- > Cheers > Douglas > > ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- @jasonbrooks ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

what happens to the status of the host when you right click on the

I'm having this same issue. Confirming the host is shut down doesn't
make a difference.
I'm seeing lots of "Failed to GlusterHostRemoveVDS, error =
Unexpected
exception" errors in my engine log that seem to correspond w/ the
failed
remove host attempts.
is cluster defined as gluster as well?
what is the status of the host after you confirm shutdown?
any error on log on this specific command?
shireesh - not sure if relevant to this flow, but need to make sure
removing a host from the engine isn't blocked on gluster needing to
remove it from the gluster cluster if the host is not available any
more, or last host in gluster cluster?
Yes, currently the system tries the 'gluster peer detach '
command when trying to remove a server, which fails if the server is
unavailable. This can be enhanced to show the error to user and then
allow 'force remove' which can use the 'gluster peer detach
*force*' command that forcefully removes the server from the cluster,
even if it is not available or has bricks on it.
what if it is the last server in the cluster?
what if there is another server in the cluster but no communication to
it as well?
A quick look at code tells me that in case of virt, we don't allow
removing a host if it has VM(s) in it (even if the host is currently
not available) i.e. vdsDynamic.getvm_count() > 0. Please correct me if
I'm wrong. If that's correct, and if we want to keep it consistent for
gluster as well, then we should not allow removing a host if it has
gluster volume(s) in it. This is how it behaves in case of 'last server
in cluster' today.
true, but user can fence the host or confirm shutdown manually, which
will release all resources on it, then it can be removed.
I see. In that case, we can just remove the validation and allow
removing the host irrespective of whether it contains volume(s) or not.
Since it's the only host in the cluster, this won't cause any harm.
In case of no up server available in the cluster, we can show the error
and provide a 'force' option that will just remove it from the engine DB
and will not attempt gluster peer detach.
something like that.
i assume the gluster storage will handle this somehow?
What would you expect gluster storage to do in such a case? If all
servers are not accessible to a gluster client, the client can't
read/write from/to volumes of the cluster. Cluster management operations
in gluster (like removing a server from the cluster) are always done
from one of the servers of the cluster. So if no servers are available,
nothing can be done. Vijay can shed more light on this if required.
Assuming that some of the servers come up at a later point in time, they
would continue to consider this (removed from engine) server as one of
the peers. This would create an inconsistency between actual gluster
configuration and the engine DB. This, however can be handled once we
have a feature to sync configuration with gluster (this is WIP). This
feature will automatically identify such servers, and allow the user to
either import them to engine, or remove (peer detach) from the gluster
cluster.
why is that an issue though - worst case the server wouldn't appear in
the admin console[1] if it is alive, and if it is dead, it is something
the gluster cluster is supposed to deal with?
[1] though i assume the admin will continue to alert on its presence for
being out-of-sync on list of servers in cluster.

So, in short I would prefer in this case that the relevant SP will do the clean-up since this is the one that is used by the code and that insures (at least I hope so) , that all related entities are removed as well. > > Thanks > > -- > Cheers > Douglas > > ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- @jasonbrooks ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Yes Gluster Service is enabled. And I can not remove hosts from that
cluster.
shireesh - please take a look at this.
dominic - move the host to a virt only cluster and delete the host.

I'm having this same issue. Confirming the host is shut

make a difference.
I'm seeing lots of "Failed to GlusterHostRemoveVDS,
error = Unexpected

correspond w/ the failed
remove host attempts.

Yes, it is.
that's a very important piece of information...
is there a more detailed exception in the log on the error?
can you uncheck gluster and try to remove it again?
Dominic - are you also using a cluster with gluster service enabled?
what is the status of the host after you confirm shutdown?
any error on log on this specific command?
I have two hosts I want to remove -- one, a failed add that never
completed, and the other, an F17 machine that I subsequently
updated to
F18. So neither of those hosts are actually connected to my engine.
Their status is either non-responsive or maintenance, if I activate,
it's the former, if I set it to maintenance, it's the latter. I
can only
attempt to remove in maintenance mode, so that's where I have them.
There don't appear to be any errors confirming manual reboot.
shireesh - not sure if relevant to this flow, but need to
make sure
removing a host from the engine isn't blocked on gluster
needing to
remove it from the gluster cluster if the host is not
available any
more, or last host in gluster cluster?

OK. Interestingly, I could not check or uncheck anything in my default cluster. The boxes were greyed out. But, I was able to remove the hosts by adding a new cluster w/o gluster enabled, moving the hosts there, and removing them. It does seem that gluster is unwilling to let hosts go, even if they aren't hosting any bricks... > > Dominic - are you also using a cluster with gluster service enabled? > > > > > >> what is the status of the host after you confirm shutdown? > >> any error on log on this specific command? > > > > I have two hosts I want to remove -- one, a failed add that never > > completed, and the other, an F17 machine that I subsequently > > updated to > > F18.

Hi , had looked in the Python script you had provided:
First, I must say that handling the database directly may leave DB
in inconsistent state, therefore, if there is no other option, the
database should be backed up prior to this operation.
In addition, I do not like the execution of the SQL statements in
the script.
There is a SP called DeleteVds(v_vds_id UUID) and you should use
that since it encapsulates all details.
For example, your script does not handle permission clean-up as
the
SP does and therefore leaves garbage in the database.
In addition, a failure in your script may leave database in
inconsistent state while the SP is executed in one transaction and
will leave DB consistent.
So, in short I would prefer in this case that the relevant SP will
do the clean-up since this is the one that is used by the code and
that insures (at least I hope so) , that all related entities are
removed as well.

In addition, a failure in your script may leave database in
inconsistent state while the SP is executed in one transaction and
will leave DB consistent.
So, in short I would prefer in this case that the relevant SP will
do the clean-up since this is the one that is used by the code and
that insures (at least I hope so) , that all related entities are
removed as well.

what happens to the status of the host when you right click on the host
and specify you confirm it was shutdown?

Hi , had looked in the Python script you had provided:
First, I must say that handling the database directly may leave DB
in inconsistent state, therefore, if there is no other option, the
database should be backed up prior to this operation.
In addition, I do not like the execution of the SQL statements in
the script.
There is a SP called DeleteVds(v_vds_id UUID) and you should use
that since it encapsulates all details.
For example, your script does not handle permission clean-up as the
SP does and therefore leaves garbage in the database.
In addition, a failure in your script may leave database in
inconsistent state while the SP is executed in one transaction and
will leave DB consistent.
So, in short I would prefer in this case that the relevant SP will
do the clean-up since this is the one that is used by the code and
that insures (at least I hope so) , that all related entities are
removed as well.
