In this video, learn about VMFS metadata errors and how you can use the VMware On-disk Metadata Analyzer to detect and resolve these errors.
- [Instructor] In this video, … I'll cover VMFS metadata errors and VOMA. … Now this is going to be a very short lesson, … and I want to just preface this by saying … this is something that has made appearances … on the VCP exam in the past, … so I want to cover it briefly, … but in real life if you run into this issue, … you're going to want to reference … a VMware knowledge base article. … And here's the KB article … that I want you to look at, 2036767. … You can see this is valid up to ESXI 6.5. … And so if you have some kind of metadata consistency problem … with a VMFS data store, … you may see errors that look like this. … Unable to commit to disk. … You may see log entries … that are indicating you have some kind of metadata problem, … like invalid metadata. … This isn't very common. … I don't expect most of you to run into this. … But if you do run into this, … the vSphere On-disk Metadata Analyzer or VOMA … can be used to check metadata consistency. … And it is a command line tool. …
