Bugs in FOG 0.33



  • Hi Tom, thanks , the service FOGMulticastManager is running…,
    from checking the file, it looks like the multicast cmd comes from /var/www/fog/lib/MulticastTask.class.php
    not sure from where and how the file and cmd gets run…


  • Senior Developer

    I believe the udp-sender is performed by the FOGMulticastManager service found in /opt/fog/service/FOGMulticastManager and started with the command:
    [code]sudo service FOGMulticastManager restart[/code]



  • Hi Tom, Thanks for that information and for r1094 update. I have applied the update and this now uses the value on fog settings>FOG_UDPCAST_STARTINGPORT, however just to make you aware there is a minor typo in the {fogwebdir}/lib/fog/Host.class.php , line 641, there is space that needs to be removed to make is work.
    Any idea where the udp-sender cmd is being sent from, as in order for multicast to work this cmd currently still needs to be send manually.
    Thanks again

    I can fix the port problem relatively easily. It’s in Host.class.php from {fogwebdir}/lib/fog/Host.class.php line 641. GIve me a few minutes and I’ll see where the port is specified (if so) from the FOG GUI. Right now it’s manually set to 666 which, as far as I can tell, it should be pulling the information from somewhere.



  • Hi Tom,
    I have been able to get multitask to work by using a partly manual process,
    I ran the following cmd on the fog server-
    gunzip -c “/images/win8/d1p1.img” | /usr/local/sbin/udp-sender --min-receivers 24 --portbase 63202 --interface eth1 --max-wait 90 --half-duplex --ttl 32 --nokbd;gunzip -c “/images/win8/d1p2.img” | /usr/local/sbin/udp-sender --min-receivers 24 --portbase 63202 --interface eth1 --max-wait 10 --half-duplex --ttl 32 --nokbd;
    this then listens for host connecting ,
    I then use the Fog to run a task to deploy to a group of ps using multitask, this the creates the job, in the /tftpboot/pxelinux.cfg/<pc mac address>
    the contents of such a file is below,
    DEFAULT fog
    LABEL fog
    KERNEL fog/kernel/bzImage
    APPEND initrd=fog/images/init.gz root=/dev/ram0 rw ramdisk_size=127000 ip=dhcp dns= mac=2c:44:fd:10:20:63 ftp=197.168.1.7 storage=197.168.1.7:/images/ storageip=197.168.1.7 web=197.168.1.7/fog/ osid=6 loglevel=4 consoleblank=0 irqpoll chkdsk=0 img=win8 imgType=mps imgid=4 PIGZ_COMP=-9 hostname=dc8300 port=666 type=down mc=yes
    Notice the PORT number is 666, I manually changed this on each is the files above to port 63202, when I ran the gunzip cmd using port 666 the multi tak did not seem to work and pc stayed waiting on the partclone screen.
    Would you be able to help or point me in the right direction,
    Which bit sets multitask to use port 666?, what mechanism caused the above gunzip cmd to run.
    Thanks Tom,
    Denis

    It shouldn’t be using partimage as I changed to partclone a while ago.

    Can you try replacing your init.gz with mine located at:

    [url]https://mastacontrola.com/fogboot/images/init.gz[/url]



  • Ok i have created the partitions using fdisk during debug mode, then retried the image process and am getting the same issue. Skips straight to ‘Task Complete’.

    Also, the /bin/fog file was using partimage by default, i haven’t changed this. Using revision 1083.

    Thanks

  • Senior Developer

    I just noticed, your text file is showing partimage now, is this your method or is this on an older revision of 0.33b?


  • Senior Developer

    Luke,

    What are you trying to image? Linux/Windows? I ask because the lines you seem to be referencing look to be for linux OS’s. If this is the case, then I’d recommend doing a debug mode and actually creating a temporary partitioning scheme for your Hard disk.

    What I mean by this, is, though it typically creates the partitions for you, sometimes uninitialized drives are completely uninitialized. This means it’s never had any type of partitioning table and FOG can’t recognize the drive in even it’s simplest of forms.

    Typically drives that are initialized with even the most simple of data, (a simple
    [code]fdisk /dev/sda >> EOF
    m
    p
    1
    +100M
    m
    p
    2

    +3000M
    t
    1
    7
    a
    1
    w
    EOF[/code]

    While this may look tricky, it really is simple. All it does is create the 100M 1st partition (win 7) and creates a second partion with 3GB. It will be overwritten when FOG starts its imaging process. This also sets the 1st partition as the bootable section as well. Though I doubt we need that fine of adjustments. The fogpartinfo, as far as I can tell, can’t tell what the drive partitions are and fails because of this. It’s simple because the drive can’t give any information appropriately to the program and fails miserably.

    Give these steps a shot, and let me know how it works. If it works, I’ll try to add it to the codebase so we don’t have this issue any more.

    Will generally do the trick to allow FOG to write to the drive with little issue. I suppose



  • Tom,

    Just had a look into to bin/fog and found the section relating to the image type I’m using (mps), the process seems to be failing at some point between these commands when imaging to a blank HDD. I’ve attached the relevant section in a text file for you.

    My guess is at lines 32 to 42 in the attached, unless Partprobe cannot read the partition table on line 28 (though ‘Checking hard disks’ returns ‘Done’). It seems to skip everything after line 30 right down to line 89 for ‘Task Complete’.

    Can you see anything that would prevent the blank HDD from being partitioned correctly? I’m at a loss currently! :(

    Thanks

    If you update to the latest and greatest of fog, the already defined messages should stop.

    Other than that, based on what you’ve provided here, I don’t see anything that’s useful yet.



  • Hi Tom, below are messages seen in /var/log/apache2/error.log file

    Let me know if you need the whole file, thanks

    Denis,

    Keep it on that screen and give me a printout of the /var/log/httpd/error_log or /var/log/apache2/error.log file.


  • Senior Developer

    I have not written the code yet, and neither did Blackout, for Multicast. I’m aware that creating a multicast task fails at the moment. I have just been trying to get everything else working more fluidly.



  • forgot to add, the issue seen when trying to multicast is that pc.s in the group stay on screen display partclone, but they never start,
    see attached image, incase its of any help to anyone. Thanks

  • Thanks Tom, I have updated to r1083, imaged pc.s no longer hang on no active task found for host…, and pc reboots after image getts deployed. Multicasting does not work yet, , many Thanks again for your help, trying to learn and understand fog better and hopefully can one day help contribute…THanks


  • Senior Developer

    /bin/fog in the init.gz file.



  • Still the same after update to revision 1083 unfortunately. Skips the partimage process and goes to task complete. I have been trying to find which file deals with the partitioning but unsure.

    Thanks
    LA


  • Senior Developer

    That would be awesome, I’ve made quite a few discoveries/changes since then.

    @Denis,

    Please try updating, 1080 - 1083 had a few changes (1080 had a typo, 1081 had a space where it shouldn’t be, 1082, found another misstep on my part, 1083, added a few more quick changes.)



  • Correct - brand new drive that hasn’t been initialized. Working on FOG rev 1016, so I can upgrade to latest revision and try that if there have been fixes with partitioning since. Will give that a go and let you know.

    Thanks!
    LA
