I would like to be able to install Operator, using the ISO, on a disk that's smaller than 8GB or so.

I'm wanting to run Operator on an embedded x86 system that boots off CF (as an IDE disk) and I don't want to have to put a larger 8GB card in when a smaller and much cheaper 2GB or 4GB card will suffice.

The VM image that you can download is less than a couple of hundred MB, so it looks like Operator doesn't need huge amounts of disk space.

Can the installation requirement in the ISO installer be changed to at least allow installation on a 4GB disk?

Obviously I'm not supporting a large number of users on this hardware, but for a small office with 10 or less extensions I believe that the hardware will be more than adequate. The hardware I'm using has a 500MHz AMD Geode and 512MB RAM - it's been designed for tasks such as Asterisk and runs a generic Asterisk install very well.

I'm keen to test this out. I'll dig up a spare board and see if I can get it to boot.

Hi,

The reason for the 8 GB is that we want to have some room for logs, voicemail messages, and possibly recorded calls.

OK - even if it is an 8GB disk that is fine - could you still install it on a flash memory based device like mentioned - say a pc engines alix board?

Yes, this should be possible.

Is there any way I can try installing on a 4GB card?
I've got a Soekris net5501 that I want to install it on as it should be perfect for this task, but I've only got a 4GB card available...

How do you go about installing it on the flash memory based computer. It doesn't have a screen output, USB or optical drive. Do I just copy the download package on via a card reader?

Now this is the tricky part. I was going to install it in a VM and then dd the raw disk over to a CF card... Worked for Kerio Control and I'm assuming it'll work for Operator.

How do you mean DD mate? If you are going to use the VM couldn't you just try and resize the size of the vm hdd before doing what you said.

Can you give me step by step on your plan though so I can try it?

I don't have a proper plan written up, and what I was doing can potentially lead to data loss too - if you're not familiar with the unix command 'dd' then you need to read up more on that first.

What I was going to do was make a xxGB virtual disk (where xx is the size of my CF card) and install Operator onto it.

Then, use dd to copy the virtual disk file block-by-block onto the CF card (this is the dangerous bit, if you get it wrong you can potentially screw up your whole system)

Finally, boot the embedded system off the CF card.

Great, thanks for that! I will pick up an 8GB card and give it a go tomorrow.

With the size of the operator disk if it is a limitation based on the fact that data potentially could be written to it - couldn't we have an option write this data to our raid volumes?

Hi,

to copy the disk image on a linux system, you can use the following commands:

vmware-mount -f <vmdk file> /mnt
dd if=/mnt/flat of=/dev/<CF card device> bs=1M count=2500

I tried doing as you said

vmware-mount -f <vmdk file> /mnt
dd if=/mnt/flat of=/dev/<CF card device> bs=1M count=2500

(vmware-mount -f /Users/danderson/Desktop/kerio-operator-appliance-1.0.0-2549 -b2-linux.vmdk /mnt
dd if=/mnt/flat of=/dev/disk1 bs=1M count=2500)

but I get this error: dd: bs: illegal numeric value

Any ideas on what I am doing wrong?

Try using a lower-case "m" for the bs=1m switch:

dd if=/mnt/flat of=/dev/<CF card device> bs=1m count=2500

Tried lowercase m but still no luck. Do I need to get the vmdk to a raw image before I do it?
