Help-could not verify mount point



  • Hello,
    were using centos 7 with FOG Version: 6971
    bzImage Version: 4.13.4
    bzImage32 Version: 4.5.0

    and had requsted to extend /images mount as it was 78%
    so as we have checked the first installtion was mounted on /dev/sdb
    without creating any Physical volume\Volume group\Logical volume
    so we couldnt extend it -
    we had to make a new disk and mount it correctly and create pv vg and lv
    and mounted it as XFS (and then i changed it to EXT4 cause i thout this caused the problems)

    now, every time we try to pull an image to a new device we get 2 errors :
    first : "EXT4-fs (ram0) : couldnt mount as ext3 due to feature incompatibilities"
    second:“could not verify mount point, check if .mntcheck exists (/bin/fog.download)”

    @batchenr Good to hear you are up and running again. Though you might have used the GUI but just as well things can go wrong when you copy on the console. Using cp /images/* /target-dir/ does not copy hidden files (files starting with a dot - like .mntcheck) because Linux bash does not include those hidden files when using the * glob. It’s as simple as that.

    IT SOLVED IT!!
    i dont know what i did worng with the copy, i moved all files in /images/* to some other dir
    and then after adding new disk moved it back… what did i do worng ? (copy throw linux not GUI)

    about all other qustion - i didnt install this fop it has installed by somone else long time ago
    i only beed requsted to extend the disk

    anyway THANK YOU!! saved me :)

    @batchenr Ok the images are still there. Let me guess, you copied those in the GUI? So you’re only missing a file that FOG uses to check after mounting the filesystem over NFS. Run the following commands and you should be fine:

    sudo -i
    touch /images/.mntcheck /images/dev/.mntcheck
    chown -R fog:root /images
    

    About the warnings in /var/log/messages - I don’t seem to find those fopen/unlink calls in the same lines in the code. So I am wondering which version you have actually installed. On the screenshot it says 6971 but that doesn’t ring a bell for me. I found an old post talking about this version but that’s from March 2016. Can you please tell us how you installed (tar.gz, svn, git) and which version/branch?

    By the way - why do you use different kernel versions for 64 bit (bzImage) and 32 bit (bzImage32)??

    @batchenr The message “EXT4-fs (ram0): couldn’t mount as ext3…” on boot is just a warning and not problematic. It’s got nothing to do with you trying to extend the /images partition! The message has been there for a long time and it’s not new.

    But the other message is a problem. I guess something went wrong when you tried to extend/move your /images store! Maybe start by running the following commands and posting the output here: mount and ls -al /images and cat /etc/fstab
