Suitable solution for HW
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? Regards, Pekka Pääkkönen

Re: Suitable solution for HW
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.

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.

Re: ALARM - ACS reboots host servers!!!
Koushik, I understand that and I will put the storage into the maintenance mode next time. However, things happen and servers crash from time to time, which is not the reason to reboot all host servers, even those which do not have any running vms with volumes on the nfs storage. The bloody agent just rebooted every single host server regardless if they were running vms with volumes on the rebooted nfs server. 95% of my vms are running from ceph and those should have never been effected in the first place. - Original Message - From: Koushik Das koushik@citrix.com To: users@cloudstack.apache.org users@cloudstack.apache.org Cc: d...@cloudstack.apache.org Sent: Monday, 3 March, 2014 5:55:34 AM Subject: Re: ALARM - ACS reboots host servers!!!

Re: ALARM - ACS reboots host servers!!!
On 03.03.2014 12:24, Andrei Mikhailovsky wrote: I am using HA for about 30% of the guest vms, but my testing showed that HA is not working reliably with KVM. It works pretty well if you initiate a vm shutdown inside a guest without using the ACS GUI. However, when the host goes down for whatever reason (power failure, init 6/0, network failure, etc.) the HA fails to kick in and restart the vms. 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. Andrei -- Sent from the Delta quadrant using Borg technology!

That should be correct.

Happens when vlan is passed in to the createNetwork call, so its immutable for the network for its entire lifecycle. Happens for Shared networks. *Remark - the difference between Implemented and Setup state. When vlanId is passed in to createNetwork call, the newly created network is marked with Setup state - meaning that its never gonna release the vlan till the network is destroyed.* *-- * *Erik* On Mon, Mar 3, 2014 at 2:17 PM, Vladimir Melnik v.mel...@uplink.ua wrote: Dear colleagues, I'm trying to add a shared network, but it doesn't become Implemented, it remains in the Setup state.

Re: CS 4.2.1 VPN connection failed
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.

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? 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). -- Sent from the Delta quadrant using Borg technology!
