Uploading to wrong storage group

[dolf]

Ok so in the mean time I messed up my test PC, so I have to deploy to it before I can try to capture again. When deploying, I got a similar issue, where the image stored on /mnt/olifant/images was “not found”.

So I upgraded to trunk. On build 8499 now.

Now I get something else:

Presumably it is trying to mount the NFS share at /mnt/olifant/images on my server to /images on the client?

[dolf]

After checking permissions, etc. according to the wiki https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_NFS , I noticed that the last two lines of /etc/exports were missing. This is how it looks now:

/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)
/mnt/olifant/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/mnt/olifant/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)

So both storage groups are on the same machine.

When deploying, the error now changes to “Unable to locate image store”.

I checked and re-submitted the settings of the image and the node on the web interface, just in case. I also checked the presence of the files at /mnt/olifant/images/IMAGE_NAME on the server. Then I cancelled the task and tried to deploy again. The web interface now shows this error:

Failed to create deployment tasking for the following hosts
No Storage Node found for this image

Resubmitting the settings pages for the storage nodes has no effect.

@dolf Look at the image’s storage groups - make sure the right group is present and set as primary (the primary is a green check box), and remove the other group, and try again.

[dolf]

@Wayne-Workman My image and storage group settings still look exactly like in the first post. I don’t see a checkbox called “primary” anywhere.

With regards to removing a storage group… I have lots of images in both groups, and I need both, so I can’t delete them, lest I lose my images.

[Wayne Workman]

@dolf I’m specifically talking about the images storage group. You’ve not posted a picture of that. Click the image, on the left is storage groups.

[dolf]

Sorry, I wasn’t aware that an image can belong to more than one storage group. The relevant images were in one group (olifant), but it wasn’t marked as primary. It is marked primary now. The same error shows up when trying to deploy:

Note that I did not sensor anything in that image. There are no hosts listed…

[Wayne Workman]

@dolf it could be that the image uploaded to /images instead of the correct directory. Can you check? ls -lahRt /images

[dolf]

Files are in the right places, IMO:

@dolf in your first post, you said you manually moved the image. Tree doesn’t show the permissions, which could be suspect. Please check those.

[dolf]

It actually does, using color, which obviously didn’t survive the copy paste. Here is the output with permissions (I already did chmod -R 777 * )

@dolf said in Uploading to wrong storage group:

/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)
/mnt/olifant/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/mnt/olifant/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)

That’s the problem I think (or at least one of them).

fsid cannot have duplicates.

You have: 0,1,0,1
They should be: 0,1,2,3

[dolf]

Changed fsids as suggested, and rebooted. No change. To be honest, I have not worked with NFS before. Thanks for the help thus far.

[Wayne Workman]

@dolf Does tree list hidden files? The command I posted does. You should have these files in these directories:
/mnt/olifant/images/.mntcheck
/mnt/olifant/images/dev/.mntcheck
/images/.mntcheck
/images/dev/.mntcheck

[dolf]

A few posts ago, I did post the output of ls - lha which shows the existence of .hidden files. They are present with the right permissions, IMO, but I pasted the output in case I overlook something.

[Wayne Workman]

Also - temporarily disable the Koei (root) storage node. It’s a check box in it’s settings.

Then see what happens.

[dolf]

No change when disabling koei. Also disabled olifant, tried again, enabled one and tried again, then both and tried again. No change.

[Wayne Workman]

@dolf Why does the olifant node have the directory /mnt/... ? In it’s description, you say it’s in lab2-server, is that the fog server or another server? Have you mounted a remote directory to the fog server?

[dolf]

I have only one physical Ubuntu machine running fog, with two hard drives. There is a storage node on each, belonging to different storage groups, so that I don’t have to have all of the images on one disk (not enough space). /mnt/olifant is simply the mount point for a physical 1.5TB internal SATA drive with one ext4 partition.

[Wayne Workman]

@dolf Ok. I’m about out of ideas then.

I’m going to need to ask for the help of @Tom-Elliott, @Moderators and @Testers for ideas.

[george1421]

@Wayne-Workman TBH I did not read the entire thread so if this has already been asked my apologies,

What is the results of showmount -e 127.0.0.1?

======
OP: If I understand this correctly you only have one FOG server but you have 2 hard drives in this physical server with each not having enough space for all of your images, do I understand this right? If so I think I would take a little different and less complex approach. There is two routes I can think of

1. Setup LVM and just add those disks to an LVM volume group and then create a LVM logical volume. Let LVM decide where to span the files on those two physical disks. Temp mount that LVM volume over /mnt and then move the content of /images to that LVM volume. Unmount /mnt and remount that new LVM volume over /images and be done with it. (make sure you update fstab). That way you are running a standard FOG configuration without having to deviate from the norm.
2. On your existing FOG server create 2 directories under /images like olifant and koei. Mount those two drives over those directories. Then when you create your image definitions make sure you pick one of the two drives. So if you create an image name called WIN7X64 make sure the destination path isn’t /images/WIN7X64 but /images/koei/WIN7X64 instead. Its not as clean as doing it at the OS level as with LVM but it should work.
