Veeam Restore Issue #VEEAM #BACKUPS #vEXPERT #VMware #vSphere

March 29, 2018 Bilal Ahmed 0

So recently I came across an issue where Veeam would restore from a backup and it would be marked as successful, but when you went to power the VM on it would fail with a CID mismatch (of course you can fix this manually by messing around in the vmdk files, but you shouldn’t need to do this). On closer inspection of the restored VM, you would see that the VEEAM RESTORE SNAPSHOT was still in place. In the restore logs I noticed : Create snapshot, ref “vm-401631”, name “VEEAM RESTORE SNAPSHOT”, description “”, memory “False”, quiesce “False” [16.02.2018 16:01:37] <01> Info [Soap] Snapshot VM ‘vm-401631’ was created. Ref: ‘snapshot-401632’ [Soap] Reverting snapshot snapshot-401632 [16.02.2018 16:07:53] <01> Info [VimApi] RevertSnapshot, type “VirtualMachineSnapshot”, ref “snapshot-401632” [16.02.2018 16:07:53] <01> Error […]

RAVELLO: Troubleshooting VSAN Network connectivity issues

March 28, 2018 Kim Bottu 0

Yesterday night, I was setting up a new VSAN cluster on Ravello and got hit with a network issue: Apparently my network was partitioned! The network for all hosts has been setup similarly on all hosts, so the network partition issue didn’t make much sense. MGMT Kernel: MGMT and vMotion traffic vmk0 10.1.0.1x VSAN Kernel: VSAN traffic vmk1 10.1.0.2x Unfortunately esxi004.vmusketeers.local had been added to a separate partition! Rather than checking each host separately, I used the VSAN PowerCLI commands to figure out if my hosts were properly configured for VSAN networking. PS C:\Windows\system32> $vsanhealth.networkhealth HostResult : {VMware.VimAutomation.Storage.Impl.V1.Vsan.Health.VsanHostNetworkHealthResultImpl, VMware.VimAutomation.Storage.Impl.V1.Vsan.Health.VsanHostNetworkHealthResultImpl, VMware.VimAutomation.Storage.Impl.V1.Vsan.Health.VsanHostNetworkHealthResultImpl, VMware.VimAutomation.Storage.Impl.V1.Vsan.Health.VsanHostNetworkHealthResultImpl} HostCommunicationFailure : HostDisconnected : HostInEsxMaintenanceMode : HostInVsanMaintenanceMode : HostWithVsanDisabled : IssueFound : True LargePingTestSuccess : False MatchingIPSubnets : True MatchingMulticastConfig […]

VCAP6-DESIGN compute calculation

March 26, 2018 Kim Bottu 0

A few weeks ago Bilal pinged me a message and asked me if I could quickly calculate the resources for an attached VCAP compute resource question. After solving the question he told me that I had created this question on our VCAP-Design sim about a year ago and that most people get the answer wrong. So what is happening here and more importantly: why? The reason why most people are unable to solve this question is because of what is assumed and hasn’t been explicitely mentioned: overhead. I always treat overhead as a mandatory input: Workloads should be able to run without contention and there should be enough free resources to run ESXi and its tasks at all times. Unfortunately a lot of people who […]

Attending AWSome Day #AWSomeDay #AWS @AWS_UKI @AWScloud

March 26, 2018 Bilal Ahmed 0

So I had the opportunity to attend this event in Manchester. As someone who has been digging into AWS this year and planning to do the cert, I thought going to this event would be worthwhile. It was also a great chance to meet other people jumping into the cloud and AWS in general. It also gave me the chance to bombard the AWS techies with questions and scenarios that were running through my mind. I bombarded both @AWSTomWoodyer and @ric__harvey with questions and they were more than happy to answer them. It was split into two tracks Technical and Management. I kept in the technical until towards the end of the day, where I then jumped into management track as they were discussing […]

Time for a change .. employee numero uno!

March 15, 2018 Kim Bottu 1

For over eight years I have been working for the same employer . It’s been a wonderful eight years: I have met lots of wonderful colleagues, some of them will remain friends for my entire life and together we have travelled to places and have spend sometimes up to 14 hours a day working alongside friends to get work done. But we always found the time to end the day with a nice dinner and some drinks. Brussels, London, Paris, Madrid, Barcelona, New York, Frankfurt, Cologne, Hong Kong and Moscow, we have visited them all in the name of work. Magical times. Over the course of eight years I became more and more VMware minded, up to the point where they started calling me ‘VMware […]
