Trouble after adding storage to /images

[arduinoAndMore]

I wasn’t sure if I should post this under Linux or under Fog since I don’t know where the issue lies exactly, but here we are.

I recently ran out of space on my FOG 7589 VM. I added a new disk to the VM and mounted it at /images following instructions here. Now when I try to capture an image, the client fails to check the mounted file system and says to check and make sure that .mntcheck exists (and it does, with the correct permissions).

The disk space pie chart in FOG itself shows the correct space in the new disk. I know FOG sees its new images directory, but for some reason clients just don’t like it after it’s mounted. Please advise. Thanks!

You may first want to update.

Next, take a look at your /etc/exports file. I’ll bet it’s still looking at /images and /images/dev instead of your new mount point.

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.
