@Sebastian-Roth i understand thank you
i’m going to set a new server and install the latest version then migrate the images
what i just wanted to say is that the actual image files are not gone so it’s like somethings small which has the info for the hard disk size or the partitions maps/ info
so i was wondering where is this located

and it just happened again

@Sebastian-Roth
ok
Running Version: 1.3.0-RC-8

hello guys, sometimes i list all images and then i find one of them becomes 0.00 iB the part where it’s written image size on client
any idea why this happens ?

@faresalandlos Well at this point I don’t think its a firewall issue, but to answer your question for ubuntu this is the command to disable the firewall sudo ufw disable

So what do I think:

1. You need to understand why nfs is not starting on that system.
2. your exports are right and once nfs is running the when you run the showmount command you should see what is posted in the /etc/exports file. The exports file is configured correctly.
3. Your /images/dev directory is not complete. You are missing the post init scripts directory.
   Your directory should look like this:

[root@sonic ~]# ls -la /images/dev
total 428
drwxrwxrwx  5 fog  fog    4096 Jun 24 13:11 .
drwxrwxrwx 18 fog  root   4096 May 28 11:11 ..
-rwxrwxrwx  1 fog  fog       0 Mar 16  2016 .mntcheck
drwxrwxrwx  2 fog  root   4096 Oct  4  2018 postinitscripts

You may need to just rerun the fog installer and it should fix this file path.

4. For your nfs service there are a number of sub services like portmapper and such that nfs depends on. Does running sudo systemctl status nfs.service give you any clue to why nfs is not starting?

thank you so much for all the help turning off the firewall fixed the problem! it’s like the system was not happy that i used FTP to play with the folders

@george1421 said in Mounting failed, connection refused:

Did the firewall get turned on, on the fog server?

From the fog server key in the following command to show the nfs shares showmount -e 127.0.0.1 post the results here.

Also lets look at the permissions for /images/dev with ls -la /images/dev (I don’t think its a file permission issue but its not known what was done via FTP)

how to deal with this firewall

@george1421

so what do you think?

when i write showmount and the IP it says only one host name is allowed

well, i simply copied images files from two old Images folders and deleted what was inside them without deleting the main Image folder, today i checked the permission for both folders images and dev and both has all rights granted
i will try to get the password for the linux machine
