Hi, I read this article and found that we can expand the VM disk online but it doesn't expand the filesystem of the VM..... I tried the following but still it didn't work..all the below commands failed on the host.. I am using :- 1. Ovirt 3.4.3 2.

Which article? virt-resize can only be used for offline expansion of disks. If you used virt-resize, what precise commands did you type and what exact errors did you see?

Please answer the question I asked:

otherwise I cannot help you.
