Setting up new storage node

[Jordonlovik]

For the life of me I can not manage to get a new storage node working. My root folder is very small and I am in need of additional space. My fog is running on a Kubuntu server with plenty of open hardrive bays. So I stuck in a new 500GB drive and formatted it to NTFS. I point the node to the new drive location on the same machine the fog is on however it never seems to take. Below are some details. I am sure its something stupid i am missing.

Here is my default member unedited - Connected with my local administrator password.

And here is my new node setup with the same password with new file path.

Here are the permissions and file path of the new drive i mounted and formatted especially for FogImages

Here is the error message i get when click on the Pie chart on the home menu of my Fog site.

If you formatted it as NTFS that is the start of your issues. It needs to be ext2, 3, or 4 in order to work correctly with FOG. Try reformatting and mounting it as ext 4 and see if that fixes your issue.

[Jordonlovik]

@ITSolutions I did what you said. formatted for Ext4 (same as Root). I am getting the same error.

Ext 4 does not allow me to create new folders so this time i just made the location /Fogdrive

After the new drive is formated and mounted and you can SEE it in the linux system,

open the CLI, go to the new image directory (wherever you mounted it)

create a .mntcheck file there, then create the dev folder and a .mntcheck file in there.

touch .mntcheck;mkdir dev;touch dev/.mntcheck

The new directory needs 777 permissions assigned to it recursively as well (you may change this later after it’s working)

I’m keeping my instructions and commands here generic so that this can help others.

chmod -R 777 /the/path/to/your/new/hdd/mount/goes/here

Then you need to add the new images and new dev folders to the exports file:

vi /etc/exports

You’ll see the two lines in there already for your old local storage node. They will have IDs, and in 1.2.0 they start at 1.
Copy those two lines, change the IDs to 3 and 4. Modify the paths so they are correct.

Then either reboot or restart NFS and RCP.

[Wayne Workman]

And obviously add the new location to your Storage Management area as a new master node (in it’s own group as well)

And I agree with @ITSolutions , it’s probably a very bad idea to try to use NTFS. I’d recommend Ext4 as he did.

@Wayne-Workman Ok so i think i followed you up untill the last part

Could you expound on what the last step does?

[Wayne Workman]

@Jordonlovik

It’s not temp.mntcheck it’s just .mntcheck

(Files that begin with a period in Linux are hidden, you can see hidden files with ls -la)

for the /etc/exports stuff, look at this: https://wiki.fogproject.org/wiki/index.php/Troubleshoot_NFS Look at the NFS Settings area in that article.

[Jordonlovik]

@Wayne-Workman So essentially I am editing the old original .mntcheck files copying their contents, editing them to reflect my new location, changing the 1 to 3 and the 2 to a 4 and then saving that data over my new .mntcheck files in the new location under /media/administrator/Fogdrive. Do I have that correct?

[Wayne Workman]

@Jordonlovik said:

Do I have that correct?

Not really no. Sorry.

the .mntcheck files are empty. They are blank. When NFS mounting occurs on the client, it then verifies that mounting was done correctly and is working. It does this by checking for a file called .mntcheck The clients do not look inside the file, they merely look to see if the file exists. Hence “mnt check”

the /etc/exports file defines what directories are exported. think of this as sharing. In that file, you should have two lines that describe your existing local storage node. Just copy those lines and past them at the end of the file, and change those two pasted lines to describe the new exported directories (wherever you mounted your hdd to). You’ll need to update their IDs. You cannot have duplicate IDs in this file. Then you save your changes, and then reboot.

Does this make sense?

[Jordonlovik]

@Wayne-Workman yes it does thank you. all i have to do is add two new lines with new IDs that correspond with the new node location.

Correct.

Plus the .mntcheck files and dev folder, and the matching stuff in the web interface afterwards.

[Jordonlovik]

@Wayne-Workman Is there any other way to edit the .mntcheck file? the vi editor is really giving me trouble through my remote session.

[Wayne Workman]

@Jordonlovik

You don’t edit the .mntcheck file. It’s supposed to be a blank file.

You simply create it with touch .mntcheck and that’s it, you are done.

http://www.linfo.org/touch.html

The touch Command
The touch command is the easiest way to create new, empty files.

[Jordonlovik]

@Wayne-Workman Sorry im saying that wrong i am actually modifying the /etc/exports file! I don’t know how or why i was thinking .mntcheck still. It looks like i may have F’ed my server over anyways. This is my first run at Linux and its been a bumpy one. I was not able to edit the /etc/Exports file because it was owned by root. So i ran the 777 permissions command not knowing the consequences. now i am getting the Sudoers is world writable error. I wish i had realize my install partitioned so idiotic by default. i have plenty of storage space its just not in the root directory where it needs to be.

[Wayne Workman]

@Jordonlovik I apologize, I should have realized. You do need “super user” permission when editing /etc/exports.

you can either A. change to super user for the duration of your session like sudo su or B. execute only one command with sudo like sudo vi /etc/exports

Poking my nose into this little 'ism. The NTFS formatted image drives, physical and virtual, that I’ve been using for over a year disagree.

Maybe I’m seeing the wrong thing.

The DefaultMember is IP address 10.1.1.201, but the new node (which I imagine is on the same server?) is set to IP 10.1.1.102

I noticed this myself. I changed that and am sill experiencing the same error.

[Jordonlovik]

At this point I am strongly considering a full reinstall of the server. Although it was labor intensive. I was just starting to experience the wonder of FOG imaging too. and I love it.

I’d recommend CentOS or Fedora. These instructions basically work for both: https://wiki.fogproject.org/wiki/index.php/Fedora_21_Server
