Re: Can I delete a unused VHD in a chain?

[Vadim Kimlaychuk]

Dear France,

 It is more than 6 months I have used vhd-util, and xe to clean-up 
manually, but I remember that if you try to destroy VDI that has a child 
- you'll get an error. Since you have all the chain from the parent you 
should start from the last child and move to the top. You shouldn't be 
able to destroy VDI in the middle of the chain, since it will definitely 
corrupt data.


 I didn't understand how exactly did you check existing VHD files?  
How do you know it is corrupted? Does vhd-util query shows that? What 
does it mean - "corrupted and not found". If it is not found, how do you 
know it is corrupted?


 Try to work with vhd-util -- it is great. I think you can resolve 
all the issues with it.

I guess coalesce will not work, if one VHD in chain is corrupted.
I guess I will have to try and repair it first.
We will see. :-)

I vageuly remember that thin provisioning was not possible with CLVM 
over ISCSI at the time of cluster setup, so I guess we do not have it.

destroy image that is a part of the chain. Of course it is more safe to

VR assigned incorrect static NAT IP

[Matthew M. Gamble]

I’m running into an odd issues with a virtual router for an isolated guest 
network on a new 4.6 installation.

The router is created successfully, however, when we assign a new static NAT IP 
the IP isn’t being added to the VR – the source NAT IP is used instead.  Right 
now I have a VR that has the source nat IP assigned to eth2, eth3, and eth4, 
and the static nat IP isn’t assigned to any interfaces.  As a result, none of 
the static nat mappings / rules are working.

I’m fairly new to debugging virtual router issues – what logs should I be 
collecting to start figuring out why the system isn’t assigning the correct IP 
to the interface in the VR?

Thanks!

Re: How to vhd-util check VHD on cLVM?

[France]

One just has to be careful if the CloudStack runs sr scan, it means the lv will 
get open and closed during your operation and might lead to problems.
In my case it closed lv before i could run repair on it. I might want to stop 
CS management servers, but because I have an idea to which chain it belongs to, 
i might just delete the template and recreate it. Hopefully this will delete 
whole chain. Noone is using it anyways.

Will make a new post about it. Hopefully next time I wont be just replying to 
myself. :-) Let’s see.

Refards,
F.

I guess i need to activate it first ‘cause it’s CLVM. :-)

lvchange -ay and then deactivate it with lvchange -an.

Will try now. Hopefully someone somewhere sometime might find this post useful.

Hello,

I did a basic setup of cloudstack and i have a problem when i add additional IP 
class to Guest -> POD

For example i added my first class /29 when i did the build of the environment 
after that i added another /29 but second one is not working. the IP appear 
like is allocated if i check the details for VM on cloudstack management but 
when i take a look on the VM I don't see IP assigned on the network card.

I want to mention that i have a 4.6 cloudstack with KVM on centOS and i tested 
the same thing on a 4.5 without any issue.

I'm not sure if this is a issue on 4.6 or i omitted something on my 
configuration.

Can i get some info why is not working ? from my understand looks like the 
additional class was not assigned on default router.


Thank you !



Regards,
Cristian

I generally do something that involves the network, you could restart it
for instance, that should notice that the VR is missing and deploy a new
one.

Re: ACS + XenServer + DAS ?

[Pierre-Luc Dion]

Nux,

You can make your DAS work if it's connected to a single XenServer and is
presented as Local Storage. That is good for a single xenserver using
localstorage, if you don't have a RAID card you might have hard time doing
software raid on xenserver to present all disks as a single storage repo.
Seams that the compute part is not specify in your bill of meterial, the
DAS need to be connected to a server, so event if you want to use this JBOD
to provide shared storage via NFS or iSCSI, you would need to connect it on
one or two servers running something like freenas.

How to vhd-util check VHD on cLVM?

[France]

Hi guys,

I want to check corrupted VHD on a XenServer cluster with LVM over ISCSI.

This is the VHD I want to check:
[root@x3 ~]# lvs | grep 1a240d45-ee0a-4c30-809b-3114dfaf85ba
  VHD-1a240d45-ee0a-4c30-809b-3114dfaf85ba
VG_XenStorage-3b6e386d-8736-6b6b-7006-f3f4df9bd586 -ri--- 136.00M 

How can I run vhd-util uppon it? 
I tried on cluster master like so, but failed:
[root@x3 ~]# vhd-util check --debug -n 
/dev/VG_XenStorage-3b6e386d-8736-6b6b-7006-f3f4df9bd586/VHD-1a240d45-ee0a-4c30-809b-3114dfaf85ba
cannot stat 
/dev/VG_XenStorage-3b6e386d-8736-6b6b-7006-f3f4df9bd586/VHD-1a240d45-ee0a-4c30-809b-3114dfaf85ba:

Please help.

RE: Router issue

[Cristian Ciobanu]

Please see the following information, i also attached some screenshots from VR 
details, i see only one Guest shared NIC.


CentOS release 6.7 (Final)
2.6.32-573.8.1.el6.x86_64


149.xxx.xx.160/29

158.xxx.xx.160/29 

  I tested the same thing on cloudstack 4.5 with the same class, without any 
issue.


Thank you

Subject: Router issue

Hello,

I did a basic setup of cloudstack and i have a problem when i add additional IP 
class to Guest -> POD

For example i added my first class /29 when i did the build of the environment 
after that i added another /29 but second one is not working. the IP appear 
like is allocated if i check the details for VM on cloudstack management but 
when i take a look on the VM I don't see IP assigned on the network card.

I want to mention that i have a 4.6 cloudstack with KVM on centOS and i tested 
the same thing on a 4.5 without any issue.

I'm not sure if this is a issue on 4.6 or i omitted something on my 
configuration.

Can i get some info why is not working ? from my understand looks like the 
additional class was not assigned on default router.


Thank you !



Regards,
Cristian

Run Windows on top of KVM+virtio? Watch out for Windows updates, system unbootable!

[Nux!]

Hi,

Just a quick heads-up! 
Someone on the CentOS ML reported his Windows 2008r2 VM on top of KVM+VirtIO PV 
ended up unbootable after he installed the SUSE Network and Storage drivers 
from the Optional Updates channel.
I've just checked now and it's the case, the system blue screens after reboot. 
Will test 2012r2 shortly.


It'd be best if you don't install those updates/drivers for now, looks like 
someone in Redmond didn't do his homework.

Hey Nux,

Something like ScaleIO might fit your use case (there is a community version as 
well the commercial version owned by EMC now)
We've had a couple of customers who swear by it for awesome performance.

Hi Lucian,

What is your use case for this project, and what are your concerns around 
network limiting your storage speed? If you put a storage front end server 
(NFS, iSCSI) on top of the DAS and link up with 10gig networking you should get 
decent performance - there’s plenty of large scale production environments 
using IP based storage. Personally I’ve ran XenServer with an iSCSI backend 
over 10gig in the past and even during ACS boot storms never managed to push 
the network links past 20-30% utilisation.

Re: Dynamic Primary Storage for VMware and KVM

[christian.kirmse]

Hi,

I was referring to the cloudstack documentation (working with storage -> best 
practices for primary storage).
According to this topic dynamic primary storage is a model where a ccp disk has 
a one to one matching to a volume in the primary storage.

Here is is the abstract from the documentation:
"Dynamic: This is a newer way for CloudStack to manage storage. In this model, 
a storage system (rather than a preallocated amount of storage) is given to 
CloudStack. CloudStack, working in concert with a storage plug-in, dynamically 
creates volumes on the storage system and each volume on the storage system 
maps to a single CloudStack volume. This is highly useful for features such as 
storage Quality of Service. Currently this feature is supported for data disks 
(Disk Offerings).”

Regards
Christian
