Trouble after adding storage to /images

[george1421]

Here are the instructions I put together for disks that use LVM. https://forums.fogproject.org/topic/6642/moving-fog-s-images-files-off-the-root-partition

If you set it up with LVM (as in the link) if you run out of space, just add a new vmdk file and then attach that new disk to the fog vg.

something else to check on the FOG server. What does the output of showmount -e 127.0.0.1 give you?

[arduinoAndMore]

@Tom-Elliott Thank you for your reply. I looked in /etc/exports and it was pointing at /images and /images/dev I’m pretty sure there’s nothing on /images/dev but the new drive is mounted at /images.

I tried changing both to point at /images and got the same result. I’m not sure if I did that right or not, but you’re right about the /etc/exports file.

[Tom Elliott]

@arduinoAndMore what’s the output of:

sudo mount

[arduinoAndMore]

@george1421

The output of showmount -e 127.0.0.1 is

Export list for 127.0.0.1
/images *

[george1421]

@arduinoAndMore yeah, you are missing the /images/dev share.

You should have

Export list for 127.0.0.1:
/images/dev *
/images     *

@arduinoAndMore I notice that /images is NOT mounted currently.

Going to guess you still need to run:

sudo mount /dev/sdb1 /images (assuming /dev/sdb is the new disk you added?)

[Tom Elliott]

@Tom-Elliott

I see this:

deu/sdbl on / images type ext3 (rw)

Did you type or copy-paste the output?

If copy-paste, then your issue (from what I can see, is you’re mounting sdb1 on / and not on /images.

[arduinoAndMore]

@Tom-Elliott

I did a screenshot and coped the text from the picture using OneNote. OCR’s fault I updated the output of sudo mount (reply below) using copy-paste over ssh.

Output of sudo mount /dev/sdb1 /images is

mount: /dev/sdb1 already mounted or /images busy
mount: according to mtab, /dev/sdb1 is already mounted in /images

[arduinoAndMore]

@george1421 This makes sense. What is the proper way to add the share? Thanks

[george1421]

@arduinoAndMore This is what I have in my /etc/exports

[root@localhost ~]# cat /etc/exports
/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)

[arduinoAndMore]

@george1421

My output is as follows. Note that I changed the second line from /images/dev to /images. I assume that’s not what I was supposed to do.

fogadmin@fogserver:~$ cat /etc/exports
/images *(ro,sync,no_wdelay,no_subtree_check,insecure_locks,no_root_squash,insecure,fsid=0)
/images *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1) 

As you mentioned in your reply I should probably see the /images/dev share in the output of showmount. How should I go about adding that new share?

[Tom Elliott]

@arduinoAndMore Your second part is wrong, you need the /dev part:

Make the second line read as:
/images/dev *(rw,async,no_wdelay,no_subtree_check,no_root_squash,insecure,fsid=1)

[george1421]

@arduinoAndMore Make sure that /images/dev exists and then just update the /etc/exports file. And finally run exportfs -a to update the shares.

[arduinoAndMore]

@george1421 @Tom-Elloitt

Content of /etc/exports

/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)

Output of showmount -e 127.0.0.1

Export list for 127.0.0.1:
/images/dev *
/images     *

I still get the message from the client saying:
“Could not verify mount point. Check if .mntcheck exists (/bin/fog.upload)”
Computer will reboot in 1 minute

[Wayne Workman]

@arduinoAndMore what is the output of this command? find /images | grep .mntcheck and this command ls -lahRt /images

[arduinoAndMore]

@Wayne-Workman said in Trouble after adding storage to /images:

find /images | grep .mntcheck

Output of find /images | grep .mntcheck is

/images/.mntcheck

Out put of ls -lahRt /imagesis

As you can see I do have one small image called MultiKiosk that is stored here already. I’m trying to capture a new Windows7 image right now.

[Tom Elliott]

@arduinoAndMore Can you please run:

sudo touch /images/dev/.mntcheck
sudo chmod -R 777 /images

[arduinoAndMore]

@Tom-Elliott …So apparently the .mntcheck file goes inside /images/dev and not just under /images? Was that really what I did wrong? facepalm

Is it just that .mntcheck should be under /images/dev or should it be in both /images/dev and /images?

It works now.

Thank you both so much for your valuable assistance! Keep up the good work!
