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?

我不太清楚，这有可能是你的硬件问题，也有可能是你在 windows 上安装的一些软件干扰了你的hyper-v存储，wsl上也有类似的错误。

我也出现了类似的问题，我不知道是什么引起的，也无法解决。这些日志会导致cpu占用增高，在我的truenas虚拟机上甚至出现了堵塞读写请求的问题。我最后使用ide控制器连接我的硬盘，来解决读写请求被堵塞的问题，但是类似的日志还会出现。

wsl社区的人反应这个问题会导致cpu利用率飙升至100%，然后阻止你对虚拟机的任何操作。但是我没有出现过这样的问题，我遇到的问题是：在我大量的读写磁盘的时候会堵塞虚拟机对磁盘的任何读取写入请求。

似乎有一个linux内核补丁可以改善这个问题，这个内核补丁被合并到了 6.14/scsi-staging。
