Script to disable time synchronization in VM… and more!

Script to disable time synchronization in VM… and more!

Time synchronization of Guest OS-es running vmware virtual machines is a very important topic that has been extensively covered in VMware documentation. General recommendation for all types of OS-es is to use external (NTP) time source and not to use VMware Tools time synchronization (with vSphere host) whenever possible. There are many good reasons for that, including but not limited to reduction of CPU overhead when using external time...

How to manage PSA claimrules and SATP rules with esxcli

How to manage PSA claimrules and SATP rules with esxcli

I will not try to explain PSA here, there is enough resources to read about it (if you asked me for recommendation I’d suggest Cormac Hogan’s excellent blog) and I don’t feel expert enough to “increase entropy” on that subject. Instead I’d like to focus on what used to be particularly confusing to me: the claimrules, SATP rules and how to manage them with esxcli. PSA behaviour can be controlled with two...

PowerCLI script to report Guest OS disk usage

PowerCLI script to report Guest OS disk usage

Anybody can have a bad day, some people claim it is best to clean one’s desk on a day like that, but I personally prefer to chase customers of my virtual infrastructure for resources they are ab-using. On many occasions projects request a lot of disk space for their virtual machines and then under-utilize these disks which is just “not cool”, especially if they require thick provisioned vmdks (which I always prefer for...

How to use partedUtil to recover damaged VMFS5 (GPT) partition table

How to use partedUtil to recover damaged VMFS5 (GPT) partition table

Personally I’m a big fan of using NFS (over 10GbE of course) storage with vSphere, I believe the performance gain that FC solutions offer is not worth the burden of dealing with block storage. In the real world however I work a lot with FC and iSCSI storage of course, so I’d like to share my experience on how to recover damaged VMFS5 (so vSphere 5.0 and above) partition using partedUtil tool, There is official KB on that matter...
