Well Pekka,

:) Do you find an answer to your question in here?
My answer(s) would have been;
no
and yes it is unnecessary. Cloudstack will orchestrate, provision and leave the 
stuff alone from there on in.

Re: CS 4.2.1 VPN connection failed

[motty cruz]

Thanks Geoff,
the problem was in CS I had to create a VPC with /16 mask and once that was
created I created network with mask /24 - to connect to client I was using
/24 but once we used mask 16, connection was successful.

thanks for your help!

Re: CS 4.2.1 VPN connection failed

[Geoff Higginbottom]

Celso,

You should be able to create new ACL lists and also change which one is applied 
to the Tier.

For the VPN return traffic you need to ensure that you have an ACL rule 
allowing the traffic.

You could simply add an allow all rule for the CIDR of the remote network in 
the appropriate ACL List.

Re: no VM statistics

[Geoff Higginbottom]

Hollman,

The usage server is an extra service which collects all of the usage data such 
as storage, bandwidth, no of VMs, Public IPs etc etc

You need to install this service on one of your management servers, and then 
configure via Global settings.

Re: ALARM - ACS reboots host servers!!!

[Marcus]

It's the standard clustering problem. Any software that does any sort
of avtive clustering is going to fence nodes that have problems, or
should if it cares about your data. If the risk of losing a host due
to a storage pool outage is too great, you could perhaps look at
rearranging your pool-to-host correlations (certain hosts run vms from
certain pools) via clusters. Note that if you register a storage pool
with a cluster, it will register the pool with libvirt when the pool
is not in maintenance, which, when the storage pool goes down will
cause problems for the host even if no VMs from that storage are
running (fetching storage stats for example will cause agent threads
to hang if its NFS), so you'd need to put ceph in its own cluster and
NFS in its own cluster.

It's far more dangerous to leave a host in an unknown/bad state. If a
host loses contact with one of your storage nodes, with HA, cloudstack
will want to start the affected VMs elsewhere. If it does so, and your
original host wakes up from it's NFS hang, you suddenly have a VM
running in two locations, corruption ensues. You might think we could
just stop the affected VMs, but NFS tends to make things that touch it
go into D state, even with 'intr' and other parameters, which affects
libvirt and the agent.

We could perhaps open a feature request to disable all HA and just
leave things as-is, disallowing operations when there are outages. If
that sounds useful you can create the feature request on
https://issues.apache.org/jira.

A shared network: State = Setup :(

Dear colleagues,

I'm trying to add a shared network, but it doesn't become "Implemented", it
remains in the "Setup" state. I tried to "restart" it, the virtual router
has started, it works, I can ping it from the Internet, but it doesn't

Can you help me to realize, where did it go wrong? What should I check?

This shuld be submitted as a bug. Which version are you on?




Regarding the nfs storage, I did not put the nfs server in the
maintenance mode. Would this solve the problem with reboots? I will
try it next time when I am doing maintenance on the nfs, but I do
recall that i've previously restarted the nfs server in the past and
I've not seen the hosts rebooting themselves. Is there a timeout which
causes the hosts to reboot?


Not sure what the timeout is, I'd be interested in finding out as well.

To the best of my knowledge, when you put primary storage in m-mode ACS 
will shut down the VMs on it.
Otherwise the shared storage is used by ACS to maintain HA (so your HA 
is as good as your shared storage ...), if link to the shared storage is 
down the host assumes something is wrong and shuts down (fences itself), 
this is the correct and expected behaviour. Maybe your network has 
segmented etc.






In any case, I think it is not safe to do an automated host server
reboot and if it was up to me I would disable this feature from the
agent. IMHO this should be down to system administrator and acs agent
should send an alert email if something goes wrong instead of
rebooting the host servers.


Not sure what to tell you, HA is a sensitive and complex subject. For 
now I'm ok with this behaviour and I see it implemented similarly in 
Xenserver, too.





I am using ceph for my primary storage for guest vms data and root
disks. The NFS is used as a backup disk offering for the guest.

 Hi Andrei, 
 
 Do you have HA enabled and did you put that primary storage in maintenance 
 mode before rebooting it? 
 It's my understanding that ACS relies on the shared storage to perform HA 
 so 
 if the storage goes it's expected to go berserk. I've noticed similar 
 behaviour in Xenserver pools without ACS. 
 I'd imagine a "cure" for this would be to use network distributed 
 "filesystems" like GlusterFS or CEPH.

Re: ALARM - ACS reboots host servers!!!

Pretty poor, I agree. 


IMHO the ACS agent should not be allowed to reboot the host server. This is not 
the type of things you would like to automate as you will eventually end up 
with broken volumes and data loss. 


And you are right of course, like what happened in my case. I currently have 
two vms which used that NFS server for volumes and the rest 50+ vms use ceph. 
As a result of the nfs server reboot all host servers have rebooted causing 50+ 
vms to reset without being properly shutdown. 


I am using ACS 4.2.1 with KVM, so this issue seems to be present on KVM + 
XenServer.

Regarding the nfs storage, I did not put the nfs server in the maintenance 
mode. Would this solve the problem with reboots? I will try it next time when I 
am doing maintenance on the nfs, but I do recall that i've previously restarted 
the nfs server in the past and I've not seen the hosts rebooting themselves. Is 
there a timeout which causes the hosts to reboot? 


In any case, I think it is not safe to do an automated host server reboot and 
if it was up to me I would disable this feature from the agent. IMHO this 
should be down to system administrator and acs agent should send an alert email 
if something goes wrong instead of rebooting the host servers. 


I am using ceph for my primary storage for guest vms data and root disks. The 
NFS is used as a backup disk offering for the guest.

Hi Andrei, 

Do you have HA enabled and did you put that primary storage in 
maintenance mode before rebooting it? 
It's my understanding that ACS relies on the shared storage to perform 
HA so if the storage goes it's expected to go berserk. I've noticed 
similar behaviour in Xenserver pools without ACS. 
I'd imagine a "cure" for this would be to use network distributed 
"filesystems" like GlusterFS or CEPH.

Re: Suitable solution for HW

[Geoff Higginbottom]

Hi Daan.

As Nux has already highlighted, disk IO is the critical factor for high 
performance database applications.

Using local storage within the Hypervisor will only provide very limited IOPS, 
even with 15k SAS disks.

We have been doing a lot of work with SolidFire storage recently. In my opinion 
they are simply the best storage option available for CloudStack, and have a 
plugin which integrates it directly with CloudStack.

Cloudstack can grow from 1 to many servers.
Re hypervisor, if you want to run databases then IO will be your main concern. 
At some point the hypervisor will not matter, your disks will matter. I'd look 
at investing in SSDs.
You can also look at conainer technology such as openvz and LXC which usually 
have better IO (since they access the hardware directly).

Hi Pääkkönen.

Cloudstack is the management/ochestration tool that lives above the
Hypervisor.

So Cloudstack manages your Xen/KVM/Hyper-V/VMWare virtualized environment.

Cloudstack is designed to manage from very few hosts to many many hundreds
of hosts.

Ronald

Hi Daan,

Maybe I should have been clearer.
I was wondering about the implications for performance. 
Would performance in a database clustering use case be better with plain Xen 
(or other virtualization solution), when compared to CloudStack with Xen?
Or is this an unnecessary concern?

Also, is CloudStack aimed for clusters consisting of tens/hundreds of such rack 
servers, or is it suitable also for smaller deployments?

I don't understand your question or you don't understand cloudstack, Pekka. 
Using cloudstack you would still need a virtualization server like Xen. If you 
are on;ly using one and don't foresee any migration of running VMs go with 
that. If you have uptime requirements that span beyond the livetime of your 
hardware, use cloudstack.

Suitable solution for HW

[Pääkkönen Pekka]

Hi,

I am planning to install virtualization or cloud solution to a rack server with 
the following spec:

Dell PowerEdge R820
+ 4 processors (Intel Xeon E5-4620), 8 cores/processor
+ 512 GB RAM
+ 8 HDD, 1 TB/disk
+ 2*1Gb, 2*10Gb network cards

A similar server would also be available.

One use case for the rack server would be serve as a cluster of database nodes 
with write-intensive workloads.

Would CloudStack be an appropriate solution for this kind of HW?
Or would a virtualization solution (for example Xen) be a better choice?

Re: ALARM - ACS reboots host servers!!!

[France]

I believe this is a bug too, because VMs not running on the storage, get 
destroyed too:


Issue has been around for a long time, like with all others I reported. 
They do not get fixed:

https://issues.apache.org/jira/browse/CLOUDSTACK-3367

We even lost assignee today.
