[Bug 511620] Re: write errors on virtual disc during install
Hi, where do I get qemu-kvm (0.12.3-0ubuntu15)? I have a lucid amd64 KVM host with similar symptoms but the available qemu-kvm version is only 0.12.3+noroms-0ubuntu9. -- write errors on virtual disc during install https://bugs.launchpad.net/bugs/511620 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Hi Dustin, That seems to work - thanks Bernhard, Dustin ; just done a lucid3 install in it (64bit) - worked fine! (Note I realised the test I did today has my host is currently running 2.6.33-999-generic #201002211003 from the daily kernel ppa rather than the standard one, I'll try and remember to redo this test using the standard kernel tomorrow - but I doubt this kernel helped).

[Bug 511620] Re: write errors on virtual disc during install
Hi Dustin,
Apologies for the delay (I mostly do stuff at the weekend).
I've just tried current Lucid with qemu-kvm 0.12.3-0ubuntu7and kernel
2.6.32-15-generic #22-Ubuntu and the
lucid-alpha3 desktop amd64 iso for the guest, and the problem is the same.
The backing disk is a raw lvm2 logical volume (/dev/mapper/main-fiddle2disk),
it's in a normal volume group with
a single physical volume of /dev/sda3 which is a partition on the SATA disk.
The failure seems to be 100% repeatable - the block number it fails at
is non-repeatable - I have tried this about 5 times now (once with this
latest version, a few more times with previous versions) and have not
had a successful installation. I have managed an installation using an
emulate SCSI disk rather than virtio.
One thing I saw today which I don't believe I had previously seen is in
the host dmesg I'm seeing some audit entries:

name=sys_rawio
but it's not clear to me that's related and you would have thought it
would have failed earlier if it couldn't do any IO??
Todays failure happened about 5% through the install and the errors in
the guest's dmesg were:
end_request: I/O error, dev vda, sector 25702959
Buffer I/O error on device vda1, logical block 3212862
SMART on the host disk still looks good ('No Errors logged').

Hi Dave- I just uploaded qemu-kvm 0.12.3 to Lucid, which includes a number of storage fixes, according to the changelog. It would be great if you could give that a test run and report back! ** Description changed: Binary package hint: qemu-kvm - (This may be #420423 but we're running a much newer kernel on lucid). + (This may be Bug #420423 but we're running a much newer kernel on + lucid). Host: Lucid 64bit uptodate as of 23rd January - i7-860 - 2.6.32-11-generic #15-Ubuntu qemu-kvm: Version: 0.12.2-0ubuntu1 Guest: lucid alpha 2 64bit iso (having pressed update-installer on it on 23rd Jan). Symptom: During install at a non-repeatable point the root filesystem of the guest becomes RO and there are dmesg logs on the guest says that there were write errors on vda1. The block numbers are different on repeated installs. There are no errors on the hosts dmesg. The disc is backed by a lvm lv, and I've tried writing it with dd if=/dev/zero of=/dev/main/fiddle2disk bs=1024k and the whole disc writes OK.

[Bug 511620] Re: write errors on virtual disc during install
I have some more interesting things to report. I'm using karmic libvirt and if I use virtual drive the lucid daily live installs fine but at reboot I get input/output errors on the virtual drive. If I emulate the hard-disk as sda drive no input/output errors are present. If you need further information I've kept all the VM's and iso to reproduce the errors I get. Maybe it's problem with lucid not the qemu-kvm? ** Changed in: qemu-kvm (Ubuntu Lucid) Status: Incomplete = New -- write errors on virtual disc during install https://bugs.launchpad.net/bugs/511620 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
