Thank you very much.
I had already found and configured it. Sorry for the oversight

where is fog assigned the IP multicast address?

@sebastian-roth

the permits were root root

if I change the path of the image in the node it does NOT create a new exports with the current

@pilar
Well, it really solved the problem of being able to access the web page, but I have tried to make a capture and it fails.
I think it always creates the images in the default path \images although in the node the specified path is not that one. Hence all the failures.
Is it possible that the images are saved in a different path than the \images directory?

@sebastian-roth
I must have explained myself wrong, I was asking if it is convenient that none of the nodes is a master node.
Simply so that when doing snapshot tasks it does not go to the node that does not belong to the path for the image to be created.

You can have storage groups, storage nodes and none of them can be a master node

Is there any place where I can check what permissions must have the directories in the fog server?

@sebastian-roth
SOLVED. Thank you very much. ENDLESS THANKS

when I try the replication it effectively ran out of space on the root partition, as I try to duplicate all the images created in the images folder of the root, but I have already left space on the root. Now there is space

I have registered a lot of hosts (about 60), from several labs, groups, images created, …, if I reinstall the fog server I lose everything or is there any way to keep what has been created?
I can’t get the database server (MariaDB) to start, so I can’t access the web interface of the FOG server (Database connection unavailable).
I think it was due to the lack of space on the system disk because I have activated the image replication without realizing it.
If I reinstall FOG it will respect me or I will be able to recover the database and all the parameters that I had and I will be able to use the images that I already had created.

I think that when I changed the storage path it did NOT find it and saved the images in the default folder \images. It started to replicate everything to the system disk and there was no space there. I still can’t access via web, is it possible to fix or recover the database?

the system disk ran out of space. The path that I put to create the fog images is on a different disk from the system, however I have seen that the repository has been duplicated in the system partition in a folder called images, I do not know why it has been duplicated, how do I do to NOT duplicate and free up space on the system?

I may clarify, I had an active task, a capture, and I realized that I had not changed the storage location, where I was there was no space, so I stopped the task and deleted it. I let it finish the activity on the host, it finished giving an error.
I deleted the image or empty container via web, created another image or empty container, indicated another storage path in the node, I left the web page. When I wanted to log in again via web, the password was no longer accepted, I tried several times and nothing and it didn’t even show me the screen to enter the credentials, it only tells me “Database connection unavailable”

the c:\fog.log of the host machine was deleted, is it possible that it is also on the server?
Sorry but I don’t see where you have suggested log files, which ones?
