Hi all,

I run my fog server on an old dedicated HP microserver with 2 separate 4 TB disks in it. A dedicated network with a 1GB dedicated switch, no uplinks. 2 USB disks are plugged in to backup to, but not even mounted.10 clients only on the dedicated network, nothing else except a couple of routers.

What speeds would you expect me to get? When all 10 servers are imaging I get 98mb which makes sense, call it 100mb, 10 clients gives 1gb through put.

Does anyone have any suggestions on how to speed it up? Imaging down is taking 4 hours for a 50 gb image? All the clients are then completing their images within a minute of each other.

Thanks

Julian

Hi All,

Why do I never seem to get the easy problems?

I use fog to image all the course machines, brilliant all working perfectly. So I thought, why don’t I use it to image my laptop, then if I ever need it, it’s a simple restore for me. Or so I thought.

The laptop works fine, no errors at all, I ran fix errors from within windows, rebooted it, the check ran fine. The disk is a SSD.

The machine is using bios, not EFI, I checked by looking for the environment variable listed here http://kb.parallels.com/en/115815

But I get
Invalid backup header but valid main header regenerating backup header from main header
Warning one or more CRCs don’t match, you should repair the disk!

I attached a photo of the screen.

Well the message is clear enough, repair the disk, but the disk isn’t GPT, at least according to disk part.

Any suggestions anyone?

Thanks

Julian

The problem was that the master node check box wasn’t selected. As it was a new storage node, it needed selecting.

Thank you all for your help. It’s much appreciated.

Julian

Tom kindly fixed it for me, I’m very grateful. I want to document it properly in case anyone else has the problem, which I’ll do tomorrow, its 23:45 here and after a week of trying to get it to work I need some beauty sleep!!

Thank you all for your help, it’s much appreciated, sleep well.

Yours

Julian

I don’t have a ftp server to test it with, so I used ftp.kernel.org, being a public site, I couldn’t actually finish the upload,

220 Welcome to kernel.org
Name (ftp.kernel.org:image): anonymous
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> put /tmp/test.txt

200 PORT command successful. Consider using PASV.
550 Permission denied.

But this is as far as I got.

Is there any other test you’d like me to perform?

Thanks

Julian

Here are some screen shots of the storage node and image details, any suggestions?

I have to get it working with the front end, although the mv command would work, In the long term I won’t be the only one using this so it needs to work fine, unfortunately.

Here’s the text from the windows ftp to the fog server,

ftp> open 10.10.1.5
Connected to 10.10.1.5.
220 (vsFTPd 3.0.2)
User (10.10.1.5:(none)): fog
331 Please specify the password.
Password:
230 Login successful.
ftp> pdw
Invalid command.
ftp> pwd
257 “/home/fog”
ftp> cd /images2
250 Directory successfully changed.
ftp> put test.txt
200 PORT command successful. Consider using PASV.
425 Failed to establish connection.

I redid this, I noticed that it didn’t transfer the file, but logged in. This suggests file/directory permissions, but my previous post shows what they were set to, are they wrong? Or should the directories be set to root root, rather than fog root?

Incidentally the machines being imaged have 2 drives in them
I’m getting desperate, I’ll have to explain to my boss why this isn’t working tomorrow, any suggestions?

The problem is now, how do I get the images named correctly and in the images2 directory instead of being named the MAC address and in the /images2/dev directory.

Thanks

Julian

I had a 4tb disk in the server, that I installed fog on. The OS and images are on this disk. I ran out of space, and added another 4 Tb disk to the fog server. It’s this new disk I’m having problems with, the old disk works fine.
The new disk is mounted as /images2.
There is no NAS involved, it’s all local, which it has to be. I’m not allowed to use anything except the 1 server, and must keep it on the network the clients are on, it’s not allowed to connect outside, to another NAS box for example.

Thanks

Julian

I’ve spent 5 hours going through this, and still can’t see it.
I’ve read through the guide Wayne suggested, and can’t seem to find the problem,

My .fogsettings are; (passwords changed)

ipaddress=“10.10.1.5”;
interface=“eth0”;
routeraddress=" option routers 10.10.1.1;“;
plainrouter=“10.10.1.1”;

snmysqluser=”"
snmysqlpass=“22222”;
snmysqlhost=“”;
installlang=“0”;
donate=“0”;
fogupdateloaded=“1”
image@fog1:/opt/fog$

I’ve checked the storage node, and the management username and management password are fog and “11111”

I’ve ftp’d from windows to the fog server, and sent a file from windows to the fog server, using the credentials fog and 11111. The file transferred fine.

I’ve reset the folders with

sudo chmod -R 777 /images2
sudo chown -R fog:root /images2.

The results of the command

ls -laR /images2 are below;

drwxrwxrwx 4 fog root 4096 Jun 1 22:32 .

image@fog1:/images$

The only thing I can find is I have no storageftppass= line, but if this was the fault, wouldn’t it affect the creation of images on the original disk, which works fine.

I have to build images next week, or my company won’t be able to run a course, and I’ll really be in trouble.

Can anyone help me out?

You could always do a “raw” image, but it’d take a long time

Thank you Wayne, your suggestion has made a big step forward.

The machine now uploads an image, but unfortunately it’s created an image in the /images2/dev directory, in a directory that is the MAC address of the machines lan card.

The image size is also 0 in the list of images
The command ls - l gives

root@fog1:/images2/dev# ls -l
total 4
drwxrwxrwx 2 root root 4096 Jun 2 22:03 e03f49af16b2
root@fog1:/images2/dev#

I thought it may be permissions, so issued

chown -R root.root /images2

But that didn’t fix it

Its the final stage that moves it from the /images2/dev to /images2 and renames it. So close…

Anyone know the next step?

Julian

Thanks for your help, much appreciated.

I issued the commands, and realised the /images2 and /images2/dev directories were not being exported. I then edited the /etc/exports file to do so. The new 4tb disk is mounted on /images2

I’ve taken a photo, now the Nfs error has gone. One down one to go.

Here’s the url of the photo;
https://www.dropbox.com/s/34lgv7b3f7fkzpc/fogerror2 (1).jpeg?dl=0

This is the result of the commands, after editing the file;

image@fog1:~$ cat /etc/exports
/images *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,fsid=1)
/images/dev *(rw,sync,no_wdelay,no_root_squash,insecure,fsid=2)
/images2 *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure,fsid=3)
/images2/dev *(rw,sync,no_wdelay,no_root_squash,insecure,fsid=4)
image@fog1:~$ ls -laR /images2 | grep .mntcheck
-rwxrwxrwx 1 root root 0 Jun 1 16:30 .mntcheck
image@fog1:~$

So it’s getting there, I’m still not sure about the password, so I’m using the “password” from the /opt/fog/.fogsettings. Is that correct? What username should I use?

Thanks

Don’t know what happened with the font there, sorry, here’s the photo

https://www.dropbox.com/s/75rigpzcy2b52mf/fogerror.jpeg?dl=0

I’ve attached a photo of the servers screen, it shows the error better. By doing this I also noticed a fail to mount error. I’m not sure I didn’t mess up the mounts from the new disk, so I’ve pasted the fstab

I’ve also issued the “sudo chmod -R 777 /images2” command, the new disk is mounted as images2.

Mod edited to use code box
[CODE]image@fog1:/etc$ cat fstab

/etc/fstab: static file system information.

Use ‘blkid’ to print the universally unique identifier for a

device; this may be used with UUID= as a more robust way to name devices

that works even if disks are added and removed. See fstab(5).

<file system> <mount point> <type> <options> <dump> <pass>

/dev/mapper/fog1–vg-root / ext4 errors=remount-ro 0 1

/boot was on /dev/sda2 during installation

/dev/sdb1 /images2 ext3 defaults 0 0

image@fog1:/etc$[/CODE]

Thanks for your help, its late here, UK 23:52, and I have to go. If you have any suggestions I’ll look at tomorrow morning, I’d be grateful and thanks in advance.

I still think I have the username / password wrong, where would you recommend I get the
correct ones from?

Julian

I added an extra disk locally to the fog server, I’m not using an NFS server. It 4Tb disks in it was the only disk, that had the OS and images on it. It’s now full, hence the need for a new disk.

Tom kindly pointed out the disk was full, as the sql server didn’t initialise.

Thanks for your help

Julian

I tried to put as much information in as possible, and forgot the actual error! Sorry it’s

Failed to mount NFS volume

Thanks for replying.
