Locked out of Fog...
- FOG Version: 1.4.3
- OS: Ubuntu 16.04.2 LTS
- Service Version:
I’m having a similar issue to the referenced topic; I created a new image and when I clicked “save” it booted me to the login screen. I’m not able to login, no error.
I issued the command, to no avail:
mysql -u root fog update globalSettings set settingValue='1' where settingKey='FOG_INACTIVITY_TIMEOUT'; exit;
I also tried restarting Apache:
service apache2 restart Job for apache2.service failed because a configured resource limit was exceeded. See "systemctl status apache2.service" and "journalctl -xe" for details.
Seems to be replicating now! Thanks!
@msnyder You will need to capture the images again (or be sneeky and move the /images/dev/<mac_name> to /images/<image_name> as the <image_name> is exactly defined in the image configuration.
mv /images/dev/<mac_name> /images/<image_name>The capture is complete it just needs to be parked in the right location.
chmod 777 /images
Will I need to recapture my image now?
@msnyder This should do the trick:
chmod 777 /images

@msnyder Make sure your permissions are set correctly for /images
They should be owned by user fog:root right or wrong the file permissions are 777
It appears that even though the capture completed on the machine, the image is staying in /images/dev/<macaddress>…
@msnyder no if the /images reconnected to /dev/sdb1 then the mount is good. Do the replicator logs in /opt/fog/log give you any idea?
I’ve captured my first image and it doesn’t seem to be replicating to my storage nodes… Could this be becasue I moved the /images to a new drive?

Yep! Thanks for your help!
@msnyder Glad you have it worked out.
just confirm now in /images and /images/dev that you have the hidden file .mntcheck with
ls -la /imagesand
ls -la /images/devand you should be all set.
I would also reboot the FOG server to make sure everything survives a reboot. That way 6 months from now you don’t wonder what happened to all of our images.
I got it…

I think I’ve messed up the FSTAB:

Did I do something wrong?
@msnyder You can start with this process: https://forums.fogproject.org/topic/6642/moving-fog-s-images-files-off-the-root-partition
Or the simpler way (if your fog server is on a virtual host server) is to just add a new disk to the virtual client.
Identify the new disk with
create a partition on the disk with
Format the partition with
mount the partition to a tmp directory like /mnt
mount -t ext4 /dev/sdX1 /mnt
Move all of the files from /images to /mnt (that the new disk is mounted over)
mv /images/* /mntand
mv /images/.* /mnt
Unmount the new disk
Update the fstab to mount /dev/sdX1 to /images.
Run the mount command to remount all of the partitions
Confirm it has been mounted
Double check to make sure the directory permissions are still accurate
Interesting that a 9GB install turned into a 95GB image before it crashed…
How would one map /images to a newly added drive?
@msnyder ok out of space is an issue for linux. Typically it will crash the OS, so if its still running you are lucky.
There shouldn’t be any images in /images/dev/<mac_address> If they are there then your captures have failed. You can delete the directories in /images/dev that are mac addresses only. There are other files in there that FOG needs to run.
You may have to purge an image directory out of /images/<image_name> to get enough free space for the OS to run. Once that is done then you have a few options. Remember that your images AND snapins are by default stored on the root partition. This is not something I like to do in a production environment, but that is the default for many linux distros.
- In crease the size of the hard drive fog is installed on
- Add a new hard drive (vmdk, vhd) to the FOG server and map that new disk over the /images directory after you copy the contents out.
Turns out I’m out of space…
I’m able to log into Bash, but can’t find the image to delete it…
@msnyder Just for clarity you can’t login into the webgui or the linux console.
What user are you trying to login as?
If you can access the FOG server linux console, can you tail the apache error log to see if its throwing an error?
