Increasing vCenter Operations Analytics vmdk size (Resizing)

[Christopher_Kus]

Hey everybody! I'm gonna start this off with a disclaimer that either I'm overly complicating the process to do this, or apparently I'm an IDIOT! Either way, a working outcome is the ideal outcome here!

Here's the situation...  I deployed vCenter Ops off of the OVA/OVF, looking good so far... And well, the environment has a need, no, a DEMAND for more storage space! So much so... that vCenter Ops itself is detecting that IT is going to run out of disk space! Perfect, right?

So, I pop into vCenter, increase the size of the disk and we should be set, right? Err, no.

For whatever the reason, again... possibly missing a particular command set...

When I try to increase the size of the disk, it keeps denynig that there is any space available, yet an fdisk -l seems to show that /dev/sdb seems to have adequate space..   Albeit, there is a KB article which 'addresses' the problem of resizing vCenter Ops, and by 'addresses' I mean, it doesn't work at all.

With me so far?  Interestingly, vCenter Ops likes to kick the Analytics part of the data into a logical volume by the name of data_vg

So, I have no ego, no commitment to this, other than trying to ensure we find the answer... and we have a source to address this for all time, instead of KB articles with no answers, or steps which end up destroying my logical volume and all of the data contained within. (Hell, if I wanted to do that, I'd just deploy the OVA again with the 'large' size)  Any help, greatly appreciated.

To add more disk space all you need to do is add an additional disk and restart the VM, it will detect and add that space to the VM.

Here is the KB

You my friend are a rockstar, thank you for that!

Now to try to 'resize' the disk which was expanded as it doesn't want to accept being smaller.. but that's a different bridge to cross.

Thank you!

Resizing a disk instead of adding a disk is NOT supported. The only way this might be solved without reinstall is by opening a VMware Support Ticket, depending on the scenario they might be able to help you get the additional space used.

Another note on your initial post. Deploying vC Ops in other then Small setup types will only give it more RAM and CPU. Disk Space always needs to be added via additional disks afterwards.
