4. Pigz abort

Pigz abort

  • C

    Hello all,

    I’m running Fog 0.32 on Ubuntu 12.04.2 LTS, and I’m trying to take a full disk image of a HP 4300 workstation. However, when it gets a minute or two into the second partition (the 500 GB windows c: drive), I get the error message:

    pigz abort write error on <stdout>

    Any suggestions would be greatly appreciated!

    Hey Tom, I appreciate you following back up on this. Currently, I do have a drive that has failed in the LVM and am waiting on my boss for a replacement.

    However, I don’t think that was the problem. As soon as I get a replacement drive, I’ll finish the upgrade process from Ubuntu 12.04 LTS to 14.04 LTS and from FOG 0.32 to 1.2.0. (The first one of these temporarily caused GRUB to break…)

    Thanks again,
    Chuck

    Am I understanding what you’re saying correctly? The reason things are failing is because the hosts file doesn’t have 127.0.0.1? Is this on the server or client?

    No problem and I hope all is working for you now.

    Ah, I see… that’s good to know! Thank you.

    That’s a problem with partimage, not with the fog system. It is rather annoying, but I don’t know how to get that to correct itself.

    I’m uploading an image right now. Built a new simple (no bonding, no LVM, simple partitioning with default /images) VM Ubuntu 12.04.2 LTS with Fog 0.32 on a 200 GB drive.

    The really funny thing is, it still reads:
    “Available space for image:…1.66 GiB = 1778888704 bytes”

    Have you had any luck, or is it still rebuilding?

    Hey Tom, I appreciate you going through all the steps with me. I just wanted to rule out something silly that I may have missed. I’m currently waiting to see if I can establish another storage node.

    Well, I hope this works for you. I’m sorry I wasn’t much help, but it sounds like it was probably just a bad drive causing all of this headache. To test, while this one is rebuilding, do you have another storage node that has enough space that you could test with?

    pvck & vgck ? Right now, I replaced one of the drives on sda5, and one of the drives on sdb1. They will need some time to rebuild.

    Do you know of any tools to test the disks within the LVM to find out if your disks are okay?

    Yes (/storage/images) is part of the LVM.

    So is /storage a part of an LVM?

    What is the output of vgdisplay?

  • C

    Thanks, Tom! That may very well be the problem. It appears I’m getting conflicting data…
    vgdisplay shows only 68.70 GB free, while df -h shows 1.2 T available.

    Then the next question is … Is /storage a raid system with a possible bad drive? I don’t know what else to check then and I’m sorry.

    Hey Tom,

    Yes, I do have everything pointing to /storage… actually /storage/images, and when I try to create new images, the new files are written there. For example, when creating the all disk image you suggested it did the following:
    /storage/images/4300AllDisk contains: d1.mbr, d1p1.img, d1p2.img, d1p3.img, d1p4.img

    The only thing is that d1p2.img is only 2G for a 456.7 G partition.

    (I’ve checked /images and the only files there are the /dev directory and the .mntcheck file)

    .mntcheck is present in /storage/images and set to 777 root:root

    Oh, and /etc/exports looks ok to me with:
    /storage/images *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)
    /storage/images/dev *(rw,sync,no_wdelay,no_root_squash,insecure)

    Thanks again,
    Chuck

    One last note,

    If you do end up changing the /etc/exports file, make sure to restart the NFS server.

    I think a simple:
    /etc/init.d/nfs restart
    will do the trick.
