Error uploading image



  • There are a couple of points I am trying to address in this post so please bear with me. I am running fog .32 on ubutnu 11.04.

    I am trying to upload a Win7 image from one of our laptops. I thought I had captured this image previously but what was on the fog server was corrupt and now I think I know why. The previous image was done from a different laptop which I do not have right now. I am having to try to redo this image from a second laptop. I watched this upload closer and saw partway through the main partition that there were several read errors after a few minutes. The image process then went on to the next partition and seemed to complete normally but I know there were errors.

    This is my first point. Why don’t I get notification that there was an error during the process? Is there a log to look at somewhere that would have a record of these errors that are being shown durning the process?

    So I went back into Windows and scheduled a complete chkdsk of drive c which was the partition that failed. It found some bad blocks in 1 file and repaired the file (according to chkdsk). Free space was checked and found no errors. The drive was defragged.

    Feeleing that I had found and fixed the problem, I started another updload. Same problem but much later into the image. I had plenty of space in the /images folder but decided to increase the space anyway and see if a fresh boot of the fog server and more space would help. (fog is running on vmware esxi / vsphere 4 - no problems expanding the partition).

    Fresh boot and new upload - same problem. DRDY error, problem reading /dev/sda3.
    Is the imaging util (partclone?) more susceptible to errors than chkdsk? Could a different kernel image make a difference?

    [edit to add - I have found another laptop that I can hopefully use to recover an image but would like to find out about these issues still]

    If you run the system in debug mode. What this means, is setup the task you’re trying to perform as a Download Debug Task (under advanced options) or Upload Debug.

    On the client, the file should be under /tmp/status.fog

    It’s just a text file, but it’s main purpose is to store the errors thrown from partimage. There are common thrown errors with is what the progress reads/gets its data from.



  • Thanks for the correction, Tom. I had seen a reference to what was used but could not remember off hand.

    The second laptop is working much better to pull an image and I am breathing a little easier now. Would still like to know about the questions I raised.

    Are the logs / results from partimage available anywhere? Is the next version of fog .33 more aware of problems like this or can it be added at some point down the road?

    It sounds to me like the original drive is beginning to fail. You could try diagnostics . Also the imaging util is part image.
