Update 2 VMWare HA Oddness... Not enough resources

Hello,

I have an issue that is quite bizarre. My cluster consists of 2 DL380G5s with 16GBs each and 2 quad core pCPUs. I have VMware HA enabled and I was trying to determine why failover did not occur when I lost one node. VMware HA is configured to allow up to 1 host failure and VMs can start if availability constraints are violated. Everything is the default settings otherwise.....

I can start several VMs after a reboot of the single node but after a bit of time I get 'Not Enough Resources'. Now this message occurs until I bring the 2nd node back into the cluster. This seems very odd to me. It is for this reason I have VMware HA capability so why is it telling me I have not enough resources? When I clearly have plenty of resources. Currently using about 1Ghz out of 8x2.333Ghz and 5.33GB out of 16GB of memory.

I thought perhaps it was an issue with the HA cluster so I rebuilt it per the KB Article (i.e. deleted the old cluster and created a new one, adding back in the host). I was able to boot VMs for a short while, then once more got into this state. I have also gone through and verified all the resources on all powered on and powered off VMs are set to the default and 'Normal' settings. One other item I have 6 Resource Pools all 'Normal & Expandable' plus 2 Resource Pools under one of them. All others have no child resource pools. It makes no difference in which resource pool I attempt to boot a VM even the parent pool of the cluster gives the same error 'Insufficient Resources'

I just fixed the other node, brought it in and all is now fine, but this is not proper. I should be able to still boot VMs anytime.... I used to be able to do so until I upgraded to Update 2. This is indeed a puzzler for me, everything looks just fine and works for a short period after boot, which is in itself peculiar.

I can reproduce this by placing the 2nd node in Maintenance mode as well.

Hi there,

Just browsing through the VMware patch and software lists (as you do on at 8:30 on a Sunday evening) and discovered this

This looks promising for at least some of our problems. Since I am not desperate enough to dial into work to test this, and we have a pesky thing called Change Control; it will be interesting to see what impact VC2.5 U3 has on HA.

If anybody beats me too it, let us know if HA has improved.

Kind regards,

Glen

VirtualCenter 2.5 Update 3 was designed to resolve the issues. There are no new features released in this build - it's all bug fixes.

Hello,

It did indead fix the problem I was seeing. I also installed the 10/3 ESX patch since it does have HA fixes in it as well.

Folks, as mentioned in a couple of the posts here, please check out VC 2.5 U3 for fixes to some of these problems. Please post your experiences here or open SRs and let VMware know if you have issues. Thanks! - VMware team
