Mounting /images/dev Permission Denied
-
@vkenny said in Mounting /images/dev Permission Denied:
So if I make my /etc/fstab look like this:
$ cat /etc/fstab
UUID=ca0220ba-82d7-434f-9231-74ba18706ac1 / ext4 defaults 1 1
UUID=20a99d10-8d99-429c-82b7-4c8655a22d22 swap swap defaults 0 0
169.254.91.1:/FOG-Share /FOG-Share nfs _netdev,defaults,user,auto,noatime,intr 0 0
169.254.91.1:/FOG-Share /images nfs _netdev,defaults,user,auto,noatime,intr 0 0then complete the necessary steps to change the storage node, this should work?
Or if not what should I do? -
@vkenny No.
You cannot reshare an nfs share.
What we’re trying to tell you, no amount of “sharing” is going to fix this for you. You could try another mounting option. Maybe CIFS/Samba from the windows share. Mounted via CIFS then the nfs side should work, but this is still fragile. -
ok, so I’m sorry this is confusing me, I’m just not grasping the direction you are providing. Sometimes I need to be told like I’m 5 yrs old… What it sounds like to me that you are saying is that I cannot use an NFS Share as a repository for images which I know is not the case…
If you could give me a few directions to follow I would be very grateful.
I also have to say the almost instant turn around in responses is exceptional. Thank you very much for such a solid support system. You guys rock!

@vkenny You cannot use an nfs share to mount and then re-export it as an nfs share.
This is what you’re currently doing.
-
Right. After 50 times of telling me I understand what you are saying. Problem is I’m now at a stand still because I don’t know a solution. Is there something else I can do to use this NFS Share as an image repo?
-
@vkenny I just told you how.
Share the volume, not as NFS, but as a windows “Share”
Mount that share via fstab using cifs or samba (whatever it’s called).
-
@vkenny Well lets start in the beginning…
The target computer must connect to the FOG server over NFS. That must happen.
The fog server in YOUR setup is connecting to an external NFS share. So this is resharing an nfs mounted share.
As Tom said, you could install SAMBA on your FOG server and then connect to your windows server over CIFS (windows share technology). Then it might work ( I say might because I have not personally done this. ).
As I posted before you could use iSCSI and connect your fog server to an iscsi target software running on your windows server.
-OR- you can setup your windows server as a FOG storage node. Then the FOS engine will connect to your windows server over NFS (that you already setup) and not have to talk to the fog server at all.

I did write a proof of concept tutorial for turning a windows server into what fog calls a storage node. ref: https://forums.fogproject.org/topic/6941/windows-server-as-fog-storage-node-proof-of-concept-blog
Without intending to sound self righteous, my first post outlined what you “could” do to use your windows server as a fog storage node.

alright. so I mounted the Windows share as cifs. I can add and remove directories to the mounted share with no issues. I made and deleted directories to assure I was connected.

You still need to install/update your database schema.

This can be done by opening a web browser and going to:

Press [Enter] key when database is updated/installed.

Setting up storage…Failed!
any ideas?

@george1421 it says at the end of the comments you are at a stand still. Does this work?

@vkenny The standstill was getting the web pages to display correctly. But that is not needed for imaging function, just for reporting to the FOG console. The imaging part should work.
Just understand that was a proof of concept document that was written quite a while ago with a different version of FOG. Will it work today??

@george1421
since I’m so close at this point, do you have any ideas on my previous post before I burn everything down and start over with your proof of concept… -
@vkenny What’s in the installers error log in regards to the setting up storage failed.
-
error log:
chmod: changing permissions of ‘/images’: Permission denied
chown: changing ownership of ‘/images’: Permission denied -
@vkenny This might be because of how you’re sharing. You haven’t done anything wrong, but it’s shared from another element.
Try running the installer with the
-Xargument. -
ran it with -X and it bypassed the storage setup which indicates failed when script is running. The /images directory still does not have the correct permissions.
what’s more is when I try to chmod or chown the /images directory I get permission denied even though I’m root, and the user used to mount cifs in fstab is in the administrators group in windows with full control.
-
@vkenny THis is because it’s shared from a windows source. Permissions must be set at the windows side, not the linux side.
-
Maybe I’m missing something, but why don’t you just add the NFS share of Windows directly as a storage option? I don’t really see the point in the reexporting, particularily because it doesn’t work by default afaik.
-
It doesn’t work by default, not only as far as you (or I) can tell, but it obviously isn’t working anyway.
@vkenny Can you just take what you’re trying to get “Windows” to do an place it on the actual FOG Server?
I don’t understand why you’re wanting this on a Windows machine. FOG doesn’t run, natively on a windows machine. So you already have a FOG Server. Why not (as @quazz suggested) take this particular “storage” and put it directly on the FOG Server?
Nothing we’ve done has worked and has been more a waste of time than it would’ve taken to have started by placing it directly on the server as it’s own storage element.

I need a Windows server containing the Storage node so, if required, someone with no *nix experience can drop images, software etc… on the storage server.
I also need the Windows server where the images are stored to have certain security protocols in place that are only officially approved for Windows. They also have these protocols for REDHAT but the licensing costs required was not approved.
Further, i need this storage node to provide storage to 5 FOG VM’s. I have an enterprise setup with 5 different VLANs and need a FOG VM for each VLAN, but need the images to be available to all VLANs/FOG VMs.
I am still getting the Permission Denied even though “Everyone” can access the CIFS shared drive… I’m so close yet so far.
Time is running out for the network maps and submission of a proof of concept. There has to be a way…
