Failed to Set Disk GUID (sgdisk -U) (restoreUUIDinformation)
-
@austinjt01 Please run the following commands on your FOG server and post output here:
md5sum /var/www/html/fog/service/ipxe/init* cat /images/<IMAGENAME>/d1.partitions
Make sure you put in the name of your image instead of
<IMAGENAME>
! -
I have our images stored on our media server, if I path over to /mnt/media-images/<IMAGENAME>/d1.partitions
This is what’s in the file
UPDATE:
I manually installed the updates and got this as the output
-

So I re-ran the FOG installer.
The md5 sums we see in the picture are definitely not the most current ones. Which installer version did you run? Where did you download FOG? I mean from github or downloaded an archive?
-
@Sebastian-Roth I ran the updates and got the same output that you have below.
Seem to still have trouble with capture / deploy though. Keeps getting hung up on “Changing hostname…”

What do you mean by “hung up”?? Please take a picture of the screen and post here.
-
It will just sit here and not do anything.
-
@austinjt01 This is the exact same picture you posted days ago. I can hardly believe you see the exact same screen again as we have changed the size of the init files and I would expect the “No space left in device” error to have vanished.
Please take a new picture of what exactly you have on screen when it hangs!
-
@Sebastian-Roth Yeah you are right, I grabbed a different laptop to test on just now and everything is fine. Thanks for your help, I really appreciate it and your support.
Edit: The capture worked this time, but the deploy gives this error.
Picture was taken just now -
@george1421 @Junkhacker Is anyone able to to reproduce this issue?!?!?

I can not duplicate the issue here, but that just means the circumstances (environment) is different.
I did see something that raised a red flag.
I have our images stored on our media server, if I path over to /mnt/media-images/<IMAGENAME>/d1.partitions
How are you doing this? You are not supposed to be able to reshare an nfs mounted share (technically you can, but fog is not configured to support it). You can’t do that in ms windows either.
Images are captured to /images/dev/<mac_address> directory (nfs share) and then “moved” to the /images/<image_name> directory using the ftp server built into the fog server. At the very least if /images/dev is on the fog server and /mnt/media-images/<image_name> is on the NFS share the ftp server will have to copy the entire image to the remote nfs server instead of just moving the file pointers as it would if the /images/dev and /images are on the same disk. If you want to store your images on an NFS nas but have the fog server manage the process there is another (unsupported) configuration you can use instead of resharing an nfs mount.

@george1421 Our storage node that we have setup is on ‘media’
‘/mnt/media-images’ is just an admin shortcut for us to navigate easier we aren’t using that for uploading or downloading. Upon capture the storage location on the FOG screen is listed as: ip address:/mnt/pool/it/images/dev/ Is it a possibility that the image is being captured into DEV but not being copied out of dev during deploy?The other thing I have to add to this, I have 7 different brands of laptops. All of the other brands work (Capture and Deploy) just fine. These new laptops we just got (30, Lenovo P52s) they are at least two years newer than any other device in our inventory. Do you think they need to be set up on UEFI instead of Legacy boot?? The only drastic difference between these machines is that they all have SSD’s which I didn’t think would make a difference?
Thanks
-
@austinjt01 is 10.228.255.10 your fog server?
-
@george1421 no, that’s the IP of our file server. .3 is the FOG server IP
-
@austinjt01 So your file server is a linux server with the fog code installed? Or is it a linux (like) nas device?
Do you have this working using the non-supported configuration where you create a second storage node and then set that node as the master? I’m still trying to understand your landscape.
-
@george1421
Our file server based on FreeNAS.I know that this isn’t supported by FOG, I guess I am just curious as to why everything will still work except for our new laptops.
‘fog’ is our master node, points to /mnt/media-images (backed by NFS) ‘media’ is an additional node, points to /mnt/pool/it/images (direct NAS). We set it up this way because the images are stored on a server with about 12 TB free currently.
-
@austinjt01 Well… I don’t have an answer why it works on everything except this laptop model.
On your freenas box you then will need the ftp service running with a user ID and password you listed in the storage node definition configured to allow the fog client to move the files. If the ftp service isn’t configured correctly your images will stay in /images/dev/<mac_address> (you will need to translate that path into your environment) and not be renamed to /images/<image_name>.
While its a little off-point and also not supported, here is a tutorial to make a synology NAS function as a FOG Storage Node: https://forums.fogproject.org/topic/9430/synology-nas-as-fog-storage-node

@george1421 @Tom-Elliott I am still wondering if the “No space left on device” was caused by another error and it’s not actually the rootfs being too small. I need to double check when booted into FOS later on but I think we don’t actually have a space issue. Should we still increase root fs size?
-
@Sebastian-Roth The “no space” is in regards to building the registry file we use to set the hostname on the machine. This happens in the /tmp space on FOS. There’s possibly something else causing the no space left (meaning it’s filling the initfs rather than the disk itself.) For example, postdownload trying to install drivers after mounting to /mnt (but the mount doesn’t actually happen)
So it may not be something we directly caused, but it is something that occurred and is related to the initfs being filled up.

I am farily sure this was the case here. I just booted a client into FOS and see that we still have 4.7 MB of free space. Doesn’t sound like much but that’s heaps for a couple of text files we generate.
I was just wondering if adding more space will cause us more trouble than it helps. More often than not I forget to tell people to update FOG settings when using the new init. Sure we can update that value in the next release but I am wondering if it’s worth it. On the other hand updating it a fair bit now will prevent us from issues that might come at some point when we keep adding to the inits little by little.

Didn’t we update this initfs to 256MB with this change to the build root config file? If I remember correctly the fog default was 100MB.
BR2_TARGET_ROOTFS_EXT2_SIZE="256M"
I’ll have to boot my last initrd file to see the free space, but 4MB sounds small. I might understand if its tempfs that is out of space. I think I remember that defaults to 4MB. That might be the space we are having issues with.
