Repeated hv_storvsc SCSI Errors on TrueNAS SCALE VM (Hyper-V)

TrueNAS General
1

I am running TrueNAS SCALE version ElectricEel-24.10.2 on a Hyper-V virtual machine hosted on Windows 10.
This VM is connected to 8 physical hard drives.
However, I occasionally encounter the following error messages in the system log:

[ 457963.529478] hv_storvsc c7b6b1ba-946e-49ee-9796-ffb1797d697f: tag#819 cmd 0x88 status: scsi 6x2 srb 0x4 hv 0xc0000001

Is this a Linux driver bug or a Hyper-V-related issue ?
Is there any way to fix or mitigate this problem?

I doubt its a linux bug… what is the storage controller. Is that passed through to the TrueNAS VM?

Hi there, I am basically having the same issue… It started all of the sudden, today in the morning everything was fine (Am TrueNAS Scale on a Hyper-V VM), and then turn off everything, only to get this error when turning it back on. What other Information would you need to help us? In my case, yes, the HDDs are passed on via a virtual SCSI Controller on the hyper-v-VM

You can now try Fangtooth, but my guess is this is a Hyper-V issue.
Are you using Windows 10 as well.?.. time to start documenting Windows versions.

Hey, much thanks for your answer… I’m actually running Windows Server 2022. 20348.3453

What do you mean with Fangtooth?

Oh… sorry, it’s the new release or truenas… still using TrueNAS 24.10.2.1

Do you think fangtooth will bring drivers to resolve the issue?
Thanks

I don’t know… you would have to test. We do not test on Hyper-V.

If it is a trueNAS issue, it would be fixed in Fangtooth or later.

Is there a way to skip this error so that I can perform the update?
