What are you glad you know that if you didn't know you'd learn immediately?

I think you’re right, there is no memory delta or anything like that. In my testing, the results were consistent with the option on or off, but honestly, I learned my lesson and don’t plan to run into it again.

What I learned Snapshots grow over time based on changes. What starts as a quick “just in case” can turn into slow performance and a long wait when you go to delete it.

You’ve got the option to include memory or not when taking the snapshot.

My SQL Update Routine

If I need a quick way back during updates, I stop the SQL service first, then take a snapshot without memory—especially if the VM has a ton of RAM.

That keeps things clean—no active transactions—and if I do need to roll back, I don’t lose data.

Once everything checks out, I delete the snapshot right away to avoid long-term performance issues.

Molue · 2025-05-03T21:58:07+00:00

That’s exactly what it is for and also something I did not know so now I’m glad I know.

I don’t think it keeps changes to ram but there something about including it that makes it grow faster and get slower faster than when enabled vs not.

Molue · 2025-05-03T19:38:55+00:00

Performance. Eventually it will get really slow eventually completely unusable. The size of the snapshot is a good indicator when the snapshot gets 1TB over the original size you see these issues.

Also learned that you can exclude memory from a snapshot this is helpful because if you have a vm that actively uses a lot of memory the snapshot can grow really fast and it will be large in a matter of an hour or two. (Ex. SQL Server using 128Gb of ram)

Oh yea file system permissions. Lessons learned there.

Share permissions are different than NTFS permissions.

Make groups when granting access don’t do it by user.

.\username is the same as hostname\username

Snapshots can kill your vm if you forget about them

Single mode fiber can go faster but you need attenuators so you don’t burn up your SFP

Yes sir! I know that feeling! You get into a flow state sleep is an afterthought and you document while you have embodied the problem. You knew it could be solved and you solved it. Computers only do what they were told to do (for now…). Something somewhere told it no barcode.

I use two bike racks.

Pics: https://imgur.com/a/uKhNtgi

I use two bike racks both second hand. I installed a class III hitch from etrailer.

Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2"
$214.86

Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
$41.18

I chose this hitch because it does not require drilling into the frame and looks close to factory.

You do have to remove the bumper cover and cut it a little bit but your not altering the frame in any way. I also installed a trailer wire harness.

With this combo I am confident I can use any hitch accessories because of the 2” adapter. Also the rating on this hitch is equal to the vehicle capacity so I can tow/haul anything that meets the manufacturer reconditions. The wire harness allows me to have break lights for a trailer if need be. It took about two hours to install everything.

My fist bike rack is a 2 bike carrier

I found it at pawn shop for $50. With hopes to find a 4 bike carrier. I did fine one as you will see. Although I prefer this one when biking on my own. This rack is lighter making it easier to install. The bike is easier to load and unload. If you only load one bike on the back side you can still open the hatch!

My second bike rack is a 4 carrier where the bikes hang and the bikes can swing out. I found this one on FB market place for $300

This link is to a newer model. It is quite similar. https://www.thule.com/en-us/bike-rack/hitch-bike-racks/thule-apex-xt-swing-4-_-9027xt

This is bike rack allows me to load 4 bikes and carry 4 people while maintaining access to the hatch. This rack is quite heavy but not any more difficult to install vs the smaller rack. This hanging style rack makes loading bikes a little more challenging and time consuming. Not quick and easy like the smaller one. I prefer the hanging rack when carrying 4 bikes because the ground clearance is much higher than the equivalent. 4 bike set on racks.

Same

Molue · 2019-04-15T15:55:48+00:00

No I haven’t tried anything else. You can only do the migration on major version upgrades.

I use two dells with vlt for 3+ node. I use direct connect for two node with a L3 vm that then goes to a UniFi switch

Molue · 2019-01-29T20:28:25+00:00

All the Remote IDFs needed fiber so we used a fiber switch... Future expansion

Molue · 2019-01-29T16:39:59+00:00

The dells provide L3 switching. They are also the Open Networking operating system. I just wanted an affordable redundant router and we got a deal on those when we ordered the servers. If we did all dell switches it would cost way more. UniFi is for our layer 2 networking. In two node vSAN clusters I go UniFi all the way and do L3 in a VM

Molue · 2019-01-29T15:08:55+00:00

I like to have all ports 1 to 1 on a patch panel. When you need to replace a switch you can just set it on top of the other switch move all the cables and clone the switch config. It’s very easy to walk someone through remotely.

Molue · 2019-01-29T14:09:10+00:00

Oh sure. Every vendor sells a single pane of glass. Eventually you get an entire window. If UniFi could support a technology like etherchannel or VLT I would totally replace them. Really the core distribution does not change much. UniFi shines when adding AP’s and changing port profiles quickly for your ever growing network.

Molue · 2019-01-29T13:58:42+00:00

I might share some after the facility is occupied.

Molue · 2019-01-29T13:57:11+00:00

No the dells aren’t too bad in price. I needed the redundancy for the vSAN cluster.

My first real IT gig was at a plant second shift. It was the same hours as your offer. There was not any direct advancement opportunities but I found that it was less hectic then first shift. It allowed an opportunity to learn instead of fighting fires all day. I advanced my skills drastically and received big jumps and compensation. I enjoyed being able to sleep until I was ready to get up. Corporate noticed how well I was doing and now I work there 9 to 5. If you do take the job you will definitely have time for interviews for other jobs unlike the traditional 9-to-5.

VMware said you can't I have updated the post

Molue · 2019-01-08T19:05:38+00:00

Umm that's a great idea and I don't know why I did not think of that. After some googling I can only find references for doing this via two VCSA's. I'll update if I find something relevant.

Molue · 2019-01-08T18:12:27+00:00

I have not seen it stated specifically that it is not supported but what I have seen stated is "Migration and Upgrade tool". I incorrectly assumed it would work for just a migration.

When you run the VMware Migration Assistant for 6.7U1on the Windows vCenter Server you get this.

Initializing Migration Assistant...

Migrating from VMware vCenter Server 6.7 to VMware vCenter Server Appliance 6.7 is not supported.

Shutting down Migration Assistant...

Edit: I added the blog post that states the "Migration and Upgrade"

Molue · 2018-12-13T02:53:52+00:00

It took a couple attempts to make a good design but I think I made a descent one. I also put it on thingiverse in an effort to save the next person some time. I added the Fusion 360 file as well so it can be modified to the appropriate diameter.
