Can I select VSAN as my placeholder datastore with SRM?

· ·

I received a question today about SRM, vSphere Replication and VSAN. The current documentation for SRM says the following:

Do not select as placeholder datastores any datastores that you use as the replication target datastore for vSphere Replication.

The question was, what about when using VSAN? As with VSAN as the source and destination datastore I usually only have 1 datastore. What do I select as my placeholder datastore then? Well with VSAN the situation is different. When using VSAN the placeholder datastore selected can be the VSAN datastore where the VMs are also replicated to. This is a gap in our current documentation, and we will make sure to get this updated asap.

Getting a 404 error with the Host Client

· ·

Just a short post. I was getting a 404 error with the Host Client when hitting https://<ip of esxi host>/ui. No clue what it was caused by. I re-installed the latest version of the host client but that didn’t solve it. Then I noticed that my endpoints.conf had “/ local” missing. You can check that as follows when logged in through SSH:

cat /etc/vmware/rhttpproxy/endpoints.conf

I did the following (edit + restarted the HTTP reverse proxy) to get it working again:

Edit the config file:

vi /etc/vmware/rhttpproxy/endpoints.conf

add the following:

/ local 8309 redirect allow

Restart the service:

/etc/init.d/rhttpproxy restart

Can all VSAN Witness VMs for ROBO be in the same VLAN?

· ·

Yesterday I received the question if all VSAN Witness VMs for ROBO can be in the same VLAN? The excellent VSAN 2 node and Stretched Cluster guide for VSAN describes an example of how things can be implemented with different VLANs for the VSAN Witness, which would look like this:

Now the question came in from a customer implementing ROBO at scale if it was possible to have all VSAN Witness VMs for ROBO in the same VLAN. The answer in short is: yes. Keep in mind that the  ROBO locations access the Witness VM over L3 and there is no multicast needed between the ROBO location. Only thing you need to do is set up the routes from the ROBO location to the main site with the central Witness VMs. All of them can be in the same VLAN, fully supported!

My Personal Top 10 Albums of All Time

· ·

Yesterday on twitter someone asked me what my personal favourite rock album was, not something I had to think about for long, in that genre there are a couple of bands for me that really stand out. When I replied to the question Christian Mohn responded as well, he had a different album in mind and based on that he wrote an article with his top 10. (Recommended read for sure!) I figured I would go through the same exercise. Not easy considering I listen to many different types of music, and there are many many albums I really like. Just like Christian I looked at some of my play stats, but they don’t necessarily reveal how I feel about an album and partly are also the result of a phase and what is happening around me.

So I sat down and started listing albums, and then started removing albums from the list. I tried to include at least 1 album from every genre I listen to, but with a strong focus on rock / alternative music. Ow, if the youtube link isn’t working in the country you live in there’s not much I can do about it… Also, if you are here purely for technology articles I appreciate that as well, just skip the article.

Here we go.

10. Elvis – If I can Dream (with the Royal Philharmonic Orchestra)
This is where it all started for me, not this particular album, but Elvis in general. My parents were fans, and as they owned a bunch of records it was what I played first on my own record player. Compared to what my friends were listening back then, if they were even listening to anything, it was a bit different… not as “current”. I guess this is where it started for me. This album in particular stands out, it has most of my favourite songs, it was released in 2015. Yes 2015, they recorded new orchestral arrangements and combined that with earlier recorded vocals. It sounds amazing. My favourite song is definitely Bridge Over Troubled Water.

Looking for the VROps VSAN Content Pack?

· ·

I just noticed the link for the VROps VSAN Content Pack had changed and it isn’t easy to find through google either. Figured I would post it quickly so at least it is indexed and easier to find. Also including the LogInsight VSAN content pack link for your convenience:
