Re: [Where are the snapshot file]

[Adrian Sender]

Hi Stravos,

A bit more info with ongoing snapshot issues with Xenserver.. your snapshots
may also be failing if your chain depth exceeds 30.

Assuming your using LVMoHBA (hardware hba), easiest way to check this is as
follows:

If the xenserver snapshot chain depth exceeds 30, you will not be able to take
any new snapshots.

You may see a similar error: (note exact error will depend on CCP / CS version..

2015-11-18 10:57:42,133 WARN  [c.c.h.x.r.XenServerStorageProcessor]
(DirectAgent-243:ctx-341ac146) (logid:65b51cbd) create snapshot operation
Failed for snapshotId: 36709, reason: SR_BACKEND_FAILURE_109The snapshot chain

Example
===
 [root@qh2-nsp04 ~]# vhd-util query -vsfd -n
/dev/VG_XenStorage-3965cb14-960e-d9d5-4ab9-608425f3ee20/VHD-7bf051ee-7762-4902-84be-4962e70a4e3e

 hidden: 0
 chain depth: 30

The best way to get the LVM path is as follows:

mysql> select * from volumes where name='ROOT-3230' \G

We are looking for the path, in this case "7bf051ee-7762-4902-84be-4962e70a4e3e"

Login to Xenserver console and do "lvscan | grep
7bf051ee-7762-4902-84be-4962e70a4e3e" This will give us VG and LV.

Then you can execute vhd-util query -vsfd -n
/dev/VG_XenStorage-3965cb14-960e-d9d5-4ab9-608425f3ee20/VHD-e00cd7a7-ae20-4b5d-a0e3-1c215d432ed4

Delete the broken snapshots from the primary storage in XenCenter.

Re: Unable to create a New VM - Error message: Unable to start instance due to Unable to get answer that is of class com.cloud.agent.api.StartAnswer

[Shweta Agarwal]

Hi Nezar,

You can find host name on detail view of SSVM in UI .
You can also use list api command listSystemVms to get the host details of 
system vms.

Thanks

Re: Unable to create a New VM - Error message: Unable to start instance due to Unable to get answer that is of class com.cloud.agent.api.StartAnswer

[Simon Weller]

Can you ssh into the Secondary Storage VM?

This can be done by getting the link-local-ip address from the infrastructure 
menu in the UI and then sshing into the host the SSVM is on and issuing this 
command as root: ssh -i /root/.ssh/id_rsa.cloud -p 3922 root@link-local-ip  
(replace link-local-ip with the link local ip).

Try  running the SSVM diangnostic script: usr/local/cloud/systemvm/ssvm-check.sh

- Si

Dell R910 - Windows 2012 R2 Cloudstack Xenserver 6.5 Dom0 Kernel Panic

[Adrian Sender]

Dear List,

In the lab I am experiencing full Dom0 host crashes on Cloudstack 4.5 and
Xenserver 6.5 using the Windows 2012 R2 VHD template from the Microsoft site.

Cannot reproduce in test on Dell R720 or Sun X4470, this appears to be
specific to Windows 2012 R2 on Dell R910 Hardware running older bios 2.10.0
(08/29/2013); this is the latest release bios for Dell R910. Note: issue also
happened with 2.5.0 Bios on Dell R910.

If you are running Dell R910 hardware in production I strongly recommend not
deploying 2012 R2 instance on the hardware.

Panic was result of CPU getting stuck (NMI), Dell does not provide BIOS
upgrade for R 910 but errata for Xeon E7-4800 family exists

Re: Unable to create a New VM - Error message: Unable to start instance due to Unable to get answer that is of class com.cloud.agent.api.StartAnswer

[Simon Weller]

Nezar,

ok, I just took a look at a pastebin you posted.

I see it complaining about the inability to find a volume prior to throwing the 
host exception.

Firstly, let's find out who host 5 is. Can you log into your MySQL server and 
run this:

use cloud;select id,name,status,type from host where id=5;

Can you post the results?

If it's a host, can you post the /var/log/cloudstack/agent/agent.log from that 
host?

And also run virsh pool-list on the host in question?

- Si

Hi Simon,

When you say "double check your routers tied to the network", do you mean
the physical routers or the virtual routers?

When I try to create a VM in Prod Environment it fails. I can't ping the
Prod virtual router from management server or Host.

But I can ping Dev virtual router from management server and Host and I was
able to create a VM in Dev Environment.

How can I troubleshoot the Prod Virtual router. I launched the console but
couldn't login.


Please note that we need to take into consideration that the affected
network is the Production network and we need to minimise service outage as
much as possible.

Your help is much appreciated,
Nezar

Re: [Where are the snapshot file]

[Adrian Sender]

Hi Stravos,

Jumping in a bit late on this thread...Can you share the exact management log
error.

We have ran CCP 4.3 with Xenserver, everything is generally ok; most common
snapshot issues are as follows:


Snapshot failing


The snapshotting on data volume DATA-3230 Failing. UI shows "Error"

2014-08-26 10:51:32,884 DEBUG [o.a.c.s.m.AncientDataMotionStrategy]

com.cloud.utils.exception.CloudRuntimeException: java.lang.NullPointerException

1. Show the details of the failing snapshot volume

mysql> select * from volumes where name=DATA-3230 \G


2. get the id of the volume from the above query and delete snapshots in the
'Ready' state.

delete from snapshot_store_ref where volume_id=3934 and state='Ready'

3. Snapshots will now succeed for volume DATA-3230.


Snapshot Failing


You may see the following in the logs:

2015-11-17 15:22:16,586 DEBUG [c.c.h.x.r.XenServerStorageProcessor]
(DirectAgent-339:ctx-6465ce91) (logid:9224bc6d) Failed to destroy pbd

'Db_exn.Uniqueness_constraint_violation("VDI", "uuid",
"e5318c7f-9434-4f1c-8695-3e82a69d2192")']]

http://support.citrix.com/article/CTX135230

Note in this example DATA-3701 snapshot is failing, but the screenshot shows
the NFS secondary storage mount for account 29, DATA-3701 belongs to account
113. So you can go through the tabs until you find
/var/cloud_mount//snapshots/113/3701 and unplug just that volume. 


In this example you will see many attached NFS secondary storage volumes on
the physical xenserver host.

1. Get the uuid of the SR from the "General" tab on the NFS storage mount.

xe sr-list uuid=84142bd7-c19c-4a39-850b-ddd30539d8ed

[root@qh2-nsp01 ~]# xe sr-list uuid=84142bd7-c19c-4a39-850b-ddd30539d8ed
uuid ( RO): 84142bd7-c19c-4a39-850b-ddd30539d8ed
 name-label ( RW):
14a68eb4-62aa-4beb-91d5-e5070ecd46a9/var/cloud_mount/b9d64979-0c47-31fe-a496-6943e9dfca63/snapshots/29/4469
   name-description ( RW):
14a68eb4-62aa-4beb-91d5-e5070ecd46a9/var/cloud_mount/b9d64979-0c47-31fe-a496-6943e9dfca63/snapshots/29/4469
   host ( RO): qh2-nsp01.nsp.nectar.org.au
   type ( RO): file
   content-type ( RO): file


2. Get the PBD UUID by using the sr-uuid from above

[root@qh2-nsp01 ~]# xe pbd-list sr-uuid=84142bd7-c19c-4a39-850b-ddd30539d8ed
uuid ( RO)  : c15627c7-a968-ac1f-9794-2e3d66c0cec4
host-uuid ( RO): 14a68eb4-62aa-4beb-91d5-e5070ecd46a9
  sr-uuid ( RO): 84142bd7-c19c-4a39-850b-ddd30539d8ed
device-config (MRO): location:
/var/cloud_mount/b9d64979-0c47-31fe-a496-6943e9dfca63/snapshots/29/4469
   currently-attached ( RO): true

3. Unplug the pdb using the uuid from above

xe pbd-unplug uuid=c15627c7-a968-ac1f-9794-2e3d66c0cec4

4. At this point you should notice the state change to broken and a red cross
through the secondary mount point in Xencenter.

5. Finally remove the sr from the host completely using the original sr uuid.

xe sr-forget uuid=84142bd7-c19c-4a39-850b-ddd30539d8ed

6 Repeat this procedure for any other attached NFS snapshot mounts, check all
xenservers.

Adrian Sender

Re: Unable to create a New VM - Error message: Unable to start instance due to Unable to get answer that is of class com.cloud.agent.api.StartAnswer

[Nezar Madbouh]

Hi Simon,

When you say "double check your routers tied to the network", do you mean
the physical routers or the virtual routers?

When I try to create a VM in Prod Environment it fails. I can't ping the
Prod virtual router from management server or Host.

But I can ping Dev virtual router from management server and Host and I was
able to create a VM in Dev Environment.

How can I troubleshoot the Prod Virtual router. I launched the console but
couldn't login.


Please note that we need to take into consideration that the affected
network is the Production network and we need to minimise service outage as
much as possible.

Your help is much appreciated,
Nezar

Re: Unable to create a New VM - Error message: Unable to start instance due to Unable to get answer that is of class com.cloud.agent.api.StartAnswer

[Simon Weller]

I've seen this before where a Virtual Router has crashed and the management 
server can't communicate with it.
Are you using an advanced network setup?

If so, double check your routers tied to the network where you are attempting 
to start an instance.

Hi Glenn,

We have 16 hosts, all KVM.

The error is not specific to Host 5. Every time I try to create a VM it
gives me the same error message but on different host.

How do I restart the agent on the host. Is it service affecting?

Thanks very much for your help.

RE: [Where are the snapshot file]

[Suresh Sadhu]

Hi Gian,

The reason might be if we delete any intermediate snapshot from  CloudStack, 
the file will not be physically removed from secondary storage(scenario 2 as 
specified in the  below article :),it will keep till  you removed the last 
snapshot. In case of xen, it maintain the snapshot chain ,once it reaches the 
limit, then it will perform full snapshot.

http://support.citrix.com/article/CTX135172

You will see intermittent issue if  the  snapshot chain lost the its chain info 
due to manually deleting of  files form secondary  or  corruption of  vdi file 
or due  to any corner cases where deleting one file instead of another 
file/restarting of ms while snapshot operation in the middle might result data 
inconsistence in between cloudstack data and Real data.


Regards
Sadhu

RE: Unable to create a New VM - Error message: Unable to start instance due to Unable to get answer that is of class com.cloud.agent.api.StartAnswer

[Suresh Sadhu]

HI Nezar,

I have checked the logs  and not finding enough information. As I requested 
earlier, please share the  host and agent state. In your logs. It shows host is 
not reachable[also not finding async job  details on this deployment].

For you ,all the vm deployments are failing on  your environment or only  few 
vmdeployment on specific host has problem.

Is it production environment or staging environment?.  It will be more helpful  
if you provide us  the agent logs to debug.

Re: IPs Getting Stuck on Multiple Routers

[Jeff Hair]

Don't think there's any real known workaround except a cron job to sync the
IPs on the router with what's in the database. This is how we solved it in
4.2. Every 3 minutes get a list of IPs from the routers, compare to DB,
then send an IpAssoc command to fix them if necessary.

But I'm looking for a better way to fix it this time. Maybe refactoring the
IP assignment in enableStaticNat to only associate/disassociate one IP at a
time would work.

RE: [Migrate from Citrix CloudPlatform 4.3 to CloudStack 4.8]

[Glenn Wagner]

Hi Gian,

Yes this can be done without breaking your environment,
I would suggest you test this in a Lab first with a copy of your production DB.

Have a look at the upgrade from 4.3 Doc with regard to the template you need to 
use for XenServer or VMware (Update System-VM templates)
http://docs.cloudstack.apache.org/projects/cloudstack-release-notes/en/4.8.0/upgrade/upgrade-4.3.html

Thanks

Re: [Migrate from Citrix CloudPlatform 4.3 to CloudStack 4.8]

[Daan Hoogland]

Yes Gian Paolo, it is possible but it will take a big effort, mostly in
planning. How big, depends on what your set-up is. The main issue is
networking. You need to ask yourself a couple of questions:
What type of networking do you use?
What type do you use and what services do your virtual routers provide?

try to construct a test environment that you can easily recreate to play
upgrades before the real thing.

Yes indeed. Currently I am fighting with the very well known "Unable to

Re: [Where are the snapshot file]

Can you post some logs from both the management server and the agent (on the 
host) when you try and delete a snapshot?

I just looked through Jira and there are quite a few issues related to 
snapshots.

Re: Certification info

[Dag Sonstebo]

Hi Venkatesh,

first of all keep in mind the exam is written against CloudStack 4.4 - so 
concentrate on the documentation for this.

You have probably already reviewed the information on the exam site:
https://www.accel-exam.jp/en/index.html

https://www.accel-exam.jp/en/objectives.html

https://www.accel-exam.jp/en/exam.html#about-accel

https://www.accel-exam.jp/en/downloads/ACCEL_brochure_en.pdf



With regards to what to study - you probably want to cover all CloudStack 
documentation as well as playing with this in the lab.

For starters:
http://docs.cloudstack.apache.org/en/master/concepts.html


http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.4/


http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/4.4/
