How to create subfolders in a storage node

[george1421]

@sdm42doc This looks like you might have a storage node configuration still in place. If you look at your last image its using the /image as the root, but the error messages in the next from the bottom its trying to move the file from /images/vol1/dev (but the image is in /images/dev).

The first picture shows that you have the right shares in place for the secondary nodes.

I didn’t read the whole thread, just the title. Another guy tried doing this but it ended up not working, I told him to undo it.

[sdm42doc]

So I tried it on my home lab, and have no good results. I don’t think it is going to work.

The uploads go up to /images/dev then only move the image name with 0MB to the /images/vol1/ folder, the other files stay in /images/dev/0050569fb7e7 d1p1.img, ect. but it looks like the image completed with no errors.

If we can trap the error we can get it fixed, so don’t give up hope on this.

Just for clarity you created the vol1 in images before you imaged the computer? (this is was a sticking point during my discussion with the devs). I’ve got 1.4.0 setup in my home lab, let me see if I can duplicate your results.

[george1421]

@george1421 Well I have sad news, it worked for me.

All I did was create a directory under /images (called vol1). The path was /images/vol1 I did change the owner to fog.root Then I setup a new image and set the path to vol1/WIn7Test and then assigned that image to a virtual box VM I have. It captured the image correctly and moved it to the /images/vol1/Win7Test directory correctly.

[sdm42doc]

@george1421 is your vol1 a directory in the /images or a separate hard drive. Mine is a separate hard drive /dev/sdb mounted to /images/vol1 when i made a directory, your right it did work fine. just not a directory mounted

[george1421]

@sdm42doc Yes it was a directory, but that should work the same as the mount point for a hard drive.

Are the permissions set correctly on that mount point after its mounted?

[george1421]

@sdm42doc We can test without imaging easy

Mount up that new drive to the vol1 mount point under /images

Then from an external computer ftp to the fog server using the user ID and password that is defined in the /opt/fog/.fogsettings file.

Navigate to the /images/vol1 directory and make a directory using the ftp client (like from a ms windows box). If you can make the directory then imaging should work. That is what the FOS engine does. It captures the image to /images/dev/<mac_address> then when done it moves the files using FTP to /images/<image_name>

[sdm42doc]

@george1421 I believe I have the rights correct, as attached, maybe you will see something I missed. I appreciate all your help!

[george1421]

@sdm42doc you have them correct. Did you try with the external ftp client yet?

I’d like to duplicate this with my home lab, but my esxi server is down with a failed power supply (one is on its way from amazon). All I have right now is my FOG-Pi server so I can’t really add a second drive to that to duplicate what you are seeing.

[sdm42doc]

@george1421 I can walk around and upload files from my desktop, create directories, ect all through that HD marked vol1 logged in as fog through ftp.

[george1421]

@sdm42doc (thinking out loud) Yet imaging fails with the error screens you posted…

FTP works, can navigate to, can create directories
permissions are set correctly
captured images going to /images/dev/<mac_name> but not being moved to /images/vol1/<image_name>
Using Ubuntu 16.04.02 with current version of FOG 1.4.0
Works with /images/vol1 as a directory not as mounted volume
== should be working
…

[sdm42doc]

@george1421 this is one of those weeks, my testing was as follows

1> physical hardware rack fog server with raid controller mirror raid with volumes / and /vol1 ubuntu 16.04.02 fog 1.4.0
2> esxi hosted fog server with two volumes / and /vol1 ubuntu 16.04.02 fog 1.4.0

tomorrow, I am going to do a fresh install on esxi, and test it accordingly and try to triplicate it and I will report back.

[george1421]

@sdm42doc Are you getting the same error as in this post with your home kit where you didn’t try to setup the storage node bits?

I can/will also duplicate with our dev lab at the office tomorrow. I can more closely emulate what you have with that environment.

[george1421]

@sdm42doc selinux is disabled on these servers, right? or at least set to permissive. I would think you would have had other issues if selinux was stepping on things.

[Tom Elliott]

I need to rethink things.
That said, however, you shouldn’t need to export the new mount point.

[sdm42doc]

@Tom-Elliott @george1421 - Here is the latest news.

I removed the mount points on the server in /etc/exports
so they only show

I uploaded an image to /images/vol1/… (and it looks successful

However, after looking into the restart on the server, the image file copies the name only with 0 kb.

Then after the temp files remain in /images/dev/macaddress, ect. and don’t move.

Now, I am confirming that a “directory” outside of a directory volume in /images/sample do work properly. Where as /images/sample is the directory with the proper rights.

Image is complete and computer restarts

Then the image is moved correctly into the directory /images/sample

My other thoughts are that I may try. Is it an ext4 thing or should I go back to ext3, and try it.

Let me know know what you think. I am willing to work with you guys for the success of this project as always! Thank you
