After Adding Storage for Images / deploy image mounting failed

[george1421]

@sourceminer I didn’t look at the wiki so I’m guessing here (well kind of).

From the command prompt of the fog server. If you run the command showmount -e 127.0.0.1 does it show both /images and /images2 exported? If no then you need to edit the /etc/exportfs file. Once the file has been updated then you want to run the command exportfs -a to reshare the shares. Check with the showmount command.

[sourceminer]

Boom that was it… Interesting I thought I did this already, I thought It was in the documentation but doesn’t seem like it was.

[sourceminer]

I spoke too soon still complaining about Unable to locate image store /bin/fog.download.
From what I see all the other parameters are correct.

exports file:
/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)
/images2 *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/images2/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)

@sourceminer What does showmount command tell you?

[sourceminer]

@george1421

root@FogServer:/bin# sudo showmount -e 127.0.0.1
Export list for 127.0.0.1:
/images2/dev *
/images2 *
/images/dev *
/images *

[george1421]

@sourceminer OK that’s great. The shares are published.

The next thing is to compare the permissions on /images and /images2

ls -la /images
ls -la /images2

Also there are hidden check files in the /images and /images/dev directories. You can view them with:
ls -la /images/*
ls -la /images/dev/*
ls -la /images2/*
ls -la /images2/dev/*

They should be called .mntcheck (yes with the preceding dot, that makes them hidden.

If you want to recreate them (if they don’t exist) use
touch /images2/.mntcheck

ls -la /images2/*

Looks like everything is correct.

@george1421
Im wondering if its not anything to do with FOG?
It gets to the preparing Partition layout and then prompts:

---

**An error has occurred.

@sourceminer Not exactly sure but maybe the duplicated fsid=X parameter in your /etc/exports is causing the issue.

[sourceminer]

@sebastian-roth
OMG that was it!!
Thank you…

[george1421]

@sebastian-roth said in After Adding Storage for Images / deploy image mounting failed:

fsid=X

I totally overlooked that. Great catch because the file systems seem to be setup correctly from a file permissions standpoint.

[sourceminer]

@george1421
Ok so I was able to deploy 1 image.
Captured a new image and trying to deploy it (from the same storage group) Getting same error again…

[george1421]

@sourceminer said in After Adding Storage for Images / deploy image mounting failed:

You get the same error on capture or capture and deploy?

If you look into /images2/dev do you see a directory with a mac formatted name? If you look at /images/dev do you see this directory? You should only see a mac address looking directory when you are doing an active upload to the fog server. Any other times that is an indication of a botched upload.

You are still getting a permission denied message?

[sourceminer]

@george1421
I captured the image no problem.
Im getting the error on deploying the image.
Neither directory has a formatted Mac name
I don’t see anything saying permission denied… just the same message above “Unable to locate image store (/bin/fog.download)”

[sourceminer]

@george1421
OK sorry, I just noted that the capture never completed… its starting over again.
Going to watch to see what happens.

[sourceminer]

OK Confirmed its all working as expected. The Ultimate solution was the duplicate fsid=x issue.
Perhaps flag the wiki document on installing additional storage pools to ensure that the fsid=x value is not duplicated from a copy and paste.

[george1421]

@sourceminer Interesting I think the wiki pages needs to be updated to based on my tutorial here: https://forums.fogproject.org/topic/10450/adding-additional-image-storage-space-to-fog-server/2

I specifically do mention changing the fsid.

[sourceminer]

@george1421
Yes your Tutorial is spot on.

One thing I have observed though, is if you reinstall Fog (I did this morning troubleshooting the Secure boot post) I noted that the exports file is replaced with default. I lost all my settings from prior. I had to append the file.

Yes I saw this too when I was developing NFSv4 for FOG. That uses a really different exports file. So now I keep a exportfs.sav file with the correct settings in case I forget in the future.
