i put this comment on a old vid so thought i would put here to make it more recent - Thank you for all the effort you put into this and your other videos. It's helping me grow my azure knowledge and by extension my career immensely! :) Really appreciate it. Keep up the great work!
You're very welcome!
Really insightful and awesome of how it works behind the scenes. Thanks John
Very welcome
So glad to hear you reiterating that one should provision a new, smaller disk and transferring data as the recommended way of "disk shrinking" in Azure, as this is the ONLY supported method of doing so.
I was literally looking into managing Azure VM disks yesterday for the AZ-800. I'm guessing Live resizing isn't going to be on the exam, but that was some info on resizing the managed disks that I hadn't seen before. This is perfect timing, thank you sir
Welcome. Live resize would not be on it since preview today.
Excellent explanation as always! 👌
Thank you very much John! As always everything was explained very clear!
You are very welcome
Super helpful - Thank you so much John !! #StayBlessednHappy
Great video and explanation as always!
Glad you liked it!
Great explanation!
Love your channel! Overdue feature that I am eagerly awaiting to get out of preview. I find it interesting on the Microsoft's preview page it says "Disks smaller than 4 TiB can't be expanded to 4 TiB or larger without downtime" You show that you were able to live resize to 4 TiB so appears the Microsoft page wording needs to be updated.
Right you can't go PAST 4TiB
1st like and thanks for this valuable video
You Sir are a champion. Fantastic explaination. Thank you, oh and btw, you are a BEAST! Maybe you have another weightlifting channel =))
Lol one channel is enough I think
Around 6m40s, you said you pay for the provisioned size of the disk. Is this not only with Premium/Ultra SKUs? That is, for standard hdd/ssd, is it not thin provisioned so that you only pay for what you use? Or is such thin provisioning only with Std SKU blob/file storage?
managed disks are all provisioned size price even standard. You are thinking of unmanaged standard storage and yes various other types of storage.
If you want to avoid the doubling of size then a disk pool is a different option. That also allows for live resizing.
A bit more complicated but you can add any size disk to the pool. Live.
This is done automatically for you on sql VMs.
Do be aware of maximum number of disks.
I mentioned this in the video as another option based on circumstance, just add disks that could then be removed.
Hi John, the documentation in Azure has changed for Linux vm, I think that now the resizing of the partitions is automatic.
Hopefully one day we'll be able to decrease in size without moving data between disks.
Who knows!
I don't know if it would be useful, but I found a script to shrink the virtual disk. With too much fear, I tried out and it worked perfectly. In the scenario I had, I shrinked a disk from 127GB to 32GB. I had to change some variables in order to attend to my scenario. It took a little bit long but in the end, it worked. if anyone wants it, I can share.
Yes there are a few out there
