This message was printed by your dom1 kernel, via the PV drivers.

Google suggests to me that txftrans.c is a Windows Vista source file,
but I don't especially want to follow that trail to far for fear of
seeing something I shouldn't.

I've no idea what the message might mean though.

I have also stopped perusing the file and error. Its just bugging me every
hour :(
I'm surprised that this error and file is never reported anywhere and I
don't think my Windows DomU is any special to generate such error.

A bit more googling suggests that TXF is Transactional NTFS
http://en.wikipedia.org/wiki/Transactional_NTFS

Furthermore http://msdn.microsoft.com/en-us/library/cc704588.aspx
("NTSTATUS values") tells me that 0xC01A002B is STATUS_LOG_STATE_INVALID
"The log service is not in the correct state to perform a requested
action."

It might be wise to run the Windows equivalent of fsck.

That wiki page suggests that TXF is not widely used, perhaps one of your
applications in the VM is one of the minority which do use it?

This seems to me like an issue which is internal to the VM but it might
still be useful to know the guest configuration. Are you using PV
drivers at all? Can you post your guest configuration please. What
version of Xen are you running etc. 

Ian.

The error code, according to this random site google found:
http://repo.meh.or.id/Windows/ntstatus.txt
means "STATUS_LOG_STATE_INVALID", which doesn't really give us much more 
leads as to what it actually does/means. It almost sounds like the code 
in that file is doing something the rest of the system is not expecting. 
C01Axxxx are all "STATUS_LOG_XXXX" error messages.

However, there are also a bunch of {4,8,C}019xxxx error messages which 
mentions transactions and similar things - it may be that at some point, 
these have been renumbered to be C01Axxxx range? No 2B in the ones I 
could find tho'.

Hi Ian,

Thanks for checking.

Its a simple Windows 2008 VM with default xs-tools PV drivers hosted on
XCP1.1 with Xen 3.4.2. It has 2 drives Local C: and iSCSI LUN D:
Local VM Disk format is lvm over iscsi and the extra disk is directly
mounted via iSCSI using iSCSI initiator within VM.

Is there anything other than this one message in the logs?

Have you looked into Windows own logging (event viewer et al?). If you
could determine which filesystem was causing this error that might give
you something to go on.

The iSCSI target is the same for both C: and D:, just the method of
connecting is different?

Ian.

I checked windows event viewer but there was no message related to NTFS,
may be it is in "Info" type and I'll probably need to search by some event
ID. I'll give another try.

C: is the normal VHD on xen. Its same as you boot a VM from local SR.
D: is the one which uses iSCSI LUN. I hope I'm not confusing.
