Well, ZFS is a non-starter. If this was not HA, I'd say screw it and set sync=disabled, since a crash will take the client out as well as the storage (just like pulling power cord). Unfortunately, in the HA storage scenario, since sync=disabled causes ZFS to lie to the iscsi daemon, the remote clien...

That's quite a project if it involves cross-hypervisor migration. Good luck! Keep me posted. Have a nice weekend. fortunately, most of the VMs had minor changes. i had no luck trying to migrate directly, instead ended up creating new VMs and configuring them to match the old ones. Yeah, a lot of fu...

If using SS, can I assume vsan just sees one large 'disk' on each side of the mirror? VSAN sees the storage underneath as one "array" to put the disks on. It can be a Storage Spaces pool, or it can be a ZFS pool. In storage spaces you can do mirrored volumes, I believe. All I want to ment...

The plan you mentioned makes sense and is doable. As a side note, I'd like to mention that StarWind CVM can be deployed on Hyper-V as described here CVM https://www.starwindsoftware.com/resource-library/starwind-virtual-san-vsan-configuration-guide-for-microsoft-windows-server-hyper-v-vsan-deployed...

Ah, thanks! I'll give that a shot!

before committing to this, I wanted to test performance in a virtual appliance setup. my storage: 2 1TB samsung 960 nvme drives. i configured a zfs appliance on local datastore (omnios, since it does zfs natively). i passed the 2 nvme drives to the the VM. in the VM, once up and running, I configure...

How much of a drop? I don't care about small decreases, but really want the security of bit-rot protection, as well as transparent lz4 compression (I've found virtual workloads to compress as high as 2X).

I ran into the same issue. Trying to go from proxmox/raw to hyperv/vhdx. On proxmox converted raw to qcow2, uploaded to hyperv and tried v2v, but it choked the same way (complaining that version 3 is not supported.). Ended up converting from raw => vmdk, uploading that, then v2v convert to vhdx.

ok that makes sense. you said 'mdadm' can i use zfs instead?

ok, so what does that red-line comment about not being supported on hyper-v and kvm mean?

I've been reading various whitepapers and such here, and am a bit lost. I've moved off ESXi to proxmox, and am wanting to move off that to hyperv. I have 3 hosts with 3 1tb nvme drives, but want to go with a 2-host setup. I seem to be seeing that the linux VSA doesn't support running on hyperv? I sa...

Unfortunately, I don't have access to the disk at this point, so I think I'll just redo that VM from scratch.

Any news?

I'm going to post it inline, since it is short: ******************* he log file name: 'logs\V2V_Log-20210107-085133.log' (PID 10708) 1/7 8:51:33.717 2268 Facility ???INFO: CV2V_ConverterApp::InitInstance: SetDllDirectory: C:\Program Files\StarWind Software\StarWind V2V Converter\lib 1/7 8:51:33.717 ...

I can't seem to upload the logfile! I browse, select it, and click on add attachment, and... nothing?
