Large Linux Samba Server On Hyper-V 2012 R2 - Caveats? Best Practices?
-
Not a tonne to know. A large Samba VM will act just like any other. At some point getting an Exablox is practical to allow for simple growth as it becomes "too much" of your hypervisor environment to make sense to be combined in. But 30TB is not all that big.

@scottalanmiller Thanks for this. So is it fair to say you'd also recommend formatting the data partition accordingly (ie: NTFS vs. Ext4)?

Definitely no NTFS on Linux. Getting away from NTFS is one of the benefits. You want XFS for a normal large data partition.

So I have a couple of questions - You're getting rid of Windows Licensing, but not Windows in general? Why use Hyper-V instead of XenServer? Is it because you're using Veeam?
Why a server instead of a NAS?

Am I correct in my understanding, from the hypervisor perspective, the VM storage partition will be NTFS, but the VM will be formatted something Linux friendly?

Hyper-V uses ReFS or NTFS, if that is what you are asking.

And the filesystem of the hypervisor has no relationship to the filesystems of the VMs. VMware uses VMFS, but the VMs are unaffected.

yes, it is. So depending on how @NashBrydges looks at it, he'll see one filesystem or another.

They're a Windows shop. They use Windows on their desktops and that's not going away. They already have Veeam so didn't make sense to move them away from something they already knew well and worked well. They already have 2 Synology NAS. One is used for local backup which is then copied over to a remote NAS at the owner's home. They also already have the R510 which is a perfect solution for their large storage needs and also supports a few other VMs.

Correct. Accessing the Hyper-V host I'll see the native file system. And the VM performs the file server function is what the users will be presented with
-
So does the host file system (NTFS) not manage the partition the VM file system is on (XFS)? Is that why @scottalanmiller is saying to separate the two? i'm a little confused how the two interact or if they interact directly/indirectly.

From what Scott is suggesting, I would create 2 VHDX. One where I'll install Linux. The other to actually hold the data. This second VHDX will be mounted to the Linux VM from within the VM and formatted from within the VM. The host will create the VHDX container and the VM will format the container and mount the container for presentation to the users. Because the 2 VHDXs have different functions (one is to run the vistual machine OS and the other just to hold data), keeping them separate appears to present some advantages for their individual intended purpose.
The host will simply set aside the "data blocks" and the VM OS will format them.

The VM's storage is just files. Literally each individual file system in the VM is a file on NTFS or ReFS. So from Hyper-V we see a series of files. To the VM they are normal disks.
