Holy shit.

Turning up internet in a building that hasn’t been used since 2008.

The old stuff.

@Pete-S said in Question about fdisk:

You're running a virtual disk under Hyper-V so physical sectors has no bearing at all.

Of course they matter, because the guest OS doesn't know or care that it is virtual.

Oh, so you thought partition alignment is about the OS?

Where did I say that? Are you implying I thought it mattered to the guest OS, because I used that term? This entire post is about fdisk and fdisk runs inside the CentOS 7 operation system in this case. That version of fdisk complains about the partition alignment as soon as you run it. It also refuses to allow you to specify sector 1 if you want to resize the partition. Thus within the OS that I am able to manage the partition from, I am unable to use fdisk as needed.

Partition alignment is only about optimizing the performance of the storage subsystem.

I know what partition alignment is actually about.

I know you seem all hot and bothered to prove me wrong about something but give it up.

And I ran that fucking mofcomp fix years ago on this server.

@RojoLoco said in Hyper-V 2012R2 unable to add boot device:

@JaredBusch clicking "apply" after adding the boot device should commit those changes. I click apply after each setting I change on any VM.

Yes, new device, change, wtf ever all apply, but there is never anything added to the boot order.

@Obsolesce said in Hyper-V 2012R2 unable to add boot device:

Very weird.

Do you have enough free space to duplicate the disk and attach it to a new VM? Not sure if that'll work, might be worth testing with a test VM and disk with same OS.

Not at the moment. In a couple months, after they move from Exchange 2013 on prem to Exchange Online I will have all the space I need for workload changes.

But a couple months does not help me know. I was hoping ot boot to gparted to see what is says about the underlying disk (see my other thread).

@dbeato said in Hyper-V 2012R2 unable to add boot device:

@JaredBusch Can you add an additional SCSI Controller and then add the DVD Drive to that new controller on the VM?

No luck.

I'll try it when the restore finishes.

As expected, deleting and creating the partition again left the system dead.

Restoring backup. Will see if that does anything with the issue of booting the VM to a DVD or not (do not expect it to).

Then I will probably recreate the VM with a new disk and restore the files from the Veeam backup instead of restore the entire VM. Way more work than I want to do just to expand this old Nextcloud instance a little.

Problem: the LVM is full. I want to expand the LVM, but first, the partition needs to see the new space. pretty basic.

Once the disk is expanded, and the user's desktop nextcloud clients can get fully synchronized again, I'll be migrating the entire thing to a new VM. But I want full clean sync first.

Additionally, because this is on CentOS 7, I cannot (easily) continue to upgrade Nextcloud. I've been meaning to deal with this side of it for a while, but it has been a low priority. I'm stuck on 20.0.14 because of MariaDB version or something.

Does deleting the DVD drive, applying that, then adding it again get it listed?

It did not add it to the list.

But when I first click New DVD drive, the Firmware changes to say boot entry changes pending.

but nothing is changed in the end.

Finally done with work and binging Stranger Things 4 with my Liesl.

I have not watched season 1 yet. This show just keeps sitting in my watchlist unwatched for some reason.

@scottalanmiller said in Question about fdisk:

That's a scary warning, but I've never had it be an issue in the past. But as always, fdisk is a bit scary.

I've done the delete and recreate larger many, many times. I have no fear of failure with that process under normal conditions.

I've just never had fdisk tell me that before.

I did go through and delete then recreate. It put the partition starting boundary on 2048 as I would expect.

I quit without writing the changes though, in order to post this.

I have an old CentOS 7 system that I need to expand the disk for.

I resized the virtual disk in Hyper-V with no issue, but I'm confused/worried about using fdisk like normal to resize the partition because of this warning.

As you can see, the disk is aligned to sector 1. Can I safely use fdisk? I cannot recall ever dealing with this before.

Windows Server 2012R2 + Hyper-V role. Yup full server.

Nextcloud instance is out of space. Yes it all says ownCloud. It has been around since 2014, but it is running Nextcloud now.

Anyway, I need to boot the thing to an ISO. I mounted the ISO, but it is not available. Upon looking more, all the UEFI virtual machines are like this. Any of the BIOS machines have all the expected options.

@scottalanmiller Not sure which of your recent videos you mentioned how screwed up the US legal system is, but I saw this in my news feed today.

Terminal should just be using OpenSSH.

This might be the issue. Will have a play after my holidays

In theory, Window's OpenSSH implementation is completely identical to the one on Linux and BSD. I can't way I've tested much in Windows 11, but on 10, it's definitely identical.

I've not had any issues with it.

Best comment ever:

The general lack of strategic direction and failure to execute is reminiscent of late Ballmer-era Microsoft or pre-Jobs 90s Apple.
