SubjectHyper-V storvsc errors with large disk image
From
(I'm not subscribed, please CC me)

Hi!

When using huge (13TB) disk images (VHDX, dynamically expanding) with
Hyper-V in Windows 8 Pro and running Linux as guest, I get errors and
hangups when accessing the emulated HD.

dmesg show the following message block looping:

sd 2:0:0:0: [sda]
Sense Key : No Sense [current]
sd 2:0:0:0: [sda]
Add. Sense: No additional sense information
hv_storvsc vmbus_0_1: cmd 0x93 scsi status 0x2 srb status 0x6

I am using the System Rescue CD 3.1.2 alternative 64 bit kernel, uname
-a says: 3.6.9-alt312-amd64

What I do i use parted to create a single partition and the run
mkfs.ext4 /dev/sda1 on it. the mkfs.ext4 process goes into D+ state
and the mentioned messages start appearing in the kernel log.

Running Window 8 as guest on the same virtual machine works fine, HD
access it without issues.

Bug in the storsvc driver?

Regards,
David
