Title:
error sda: WRITE SAME failed when installing package
To manage
Hello,
Verified this problem with 3.13.0-14-generic OS on a KVM guest running
on Power 8 and the issue is no more reproducible
I tried the mentioned scenarios like
- apt-get install perl*
- dio test run from LTP
Both scenarios were successfull with out any problem or error message in
dmesg
Has this kernel been copied out of the guest into the host? The way to
confirm from inside the host is to use:
cat /proc/version_signature

Yes I copied the kerenel image to the guest.
the below is used to open my guest
KERNEL=vmlinux-3.13.0-0-generic
#FSIMAGE=trusty-server-cloudimg-ppc64el.img
FSIMAGE=trusty-server-cloudimg-ppc64el.img.qcow2
MEM=8G
qemu-system-ppc64 \
-enable-kvm -M pseries -cpu POWER8 -smp
I had same error of sda: WRITE SAME failed. Manually zeroing. when
running the dio tests of LTP test suite on my ubuntu .
on other terminal of the guest I had error displayed as below :
sda: WRITE SAME failed. Manually zeroing.
and in dmesg also the error was collected , I will be pasting only
For more info I have the below kernel
root@ubuntu:/opt/ltp# dpkg --list | grep linux
ii libselinux1:ppc64el 2.2.1-1ubuntu2
ppc64el SELinux runtime shared libraries
ii libv4l-0:ppc64el1.0.0-1
I tested by upgrading my kernel using apt-get dist-upgrade command. I
tried the same scenario that is mentioned in the bug after upgrade.
This is the state on my guest
root@ubuntu:~# dpkg --list | grep linux
ii libselinux1:ppc64el 2.2.1-1ubuntu2 ppc64el
you can get the guest access by logging into 9.3.189.114(root/.pasroot)
cd /var/lib/libvirt/images/harini/bug_verify_image
run ./kvmg_p8 -- this has qemu command and this will get the console for
guest.

The Ubuntu-3.13.0-0.15 kernel has been copied into the bootstrap archive
and should be available for update. This kernel is based on the
v3.13-rc7 kernel. If we could retest with that kernel that would help.
Please report any testing here.
