So I am trying to perform a database cleanup for this issue. I am not good with Linux at all. Can someone help me out with this? I’m stupid with this back end stuff. Fog has been running fine for months now I get this issue with trying to associate an image to a group. I’ve restarted the machine twice - no luck. I need this fixed - have a lot of computers to image!
@sebastian-roth Well I ran into a snag by not being able to multicast to deploy images. So for now I have left the Fog server as the master node. If I run into a space issue further down the road I can always move images over to the NAS and vice-versa. Space was really the only reason for using the NAS.
So I’ve looked around and found a few posts regarding using a NAS device for storing the /images directory. I am setting up Ubuntu & Fog on a retired server that has some decent hardware (perfect for Fog).
My question is - can I run a normal fog install? or do I have to use storage install? If I run normal is there an easy method to mount or redirect the /images directory to a share on the NAS (I already have the share on the NAS setup). I did watch a YouTube video that walks you through a storage node install but that is assuming I already have an existing Fog server running.
Also, what network protocols (if any) do I need to have setup on the NAS for simple communication between the Fog server and the NAS? The NAS is a Synology rack mounted in our main network rack.
UPDATE: So will this tutorial work for a Synology NAS? https://wiki.fogproject.org/wiki/index.php?title=Use_FOG_with_FreeNAS
The VM nic is bridged. No other VMs running on the host.
By the way, I am setting up another Fog server to replace this one as its on my to-do list. What Ubuntu version is preferred; Ubuntu desktop or server?
Should I reinstall Fog? If so, does it wipe out my images directory? I ask this because I now have my new NAS appliance installed and I have a spare server that’s been decommissioned that I could setup with Ubuntu and install Fog on with a storage node install type.
@george1421 From Linux I cannot ping anything. Everything else is communicating fine so its not a network issue.
So I have Fog server running on a VM via VirtualBox. The server lost power so I had to restart everything. Now I can’t login nor ping my Fog server IP. I don’t have a Ubuntu GUI so I am wondering how I can fix this via command line. Can someone help me out?
UPDATE: After doing some investigation of the network device(s) configuration; I discovered the multicast looks to be configured properly on the router and switch stack.
For curiosity sake, I have attempted a multicast session for 4 laptops - my transfer rate is approximately 1.85GB/per min. This is exciting. I am going to gradually increase the load from there. If I can get away with 8 devices at a time that would be ideal.
Its strange because I know for a fact upon my first attempt a month ago, multicasting was terrible; it was virtually stationary.
@george1421 - After looking at the running config on my router; “ip pim sparse-dense-mode” is enabled on the data VLAN. I’ve also looked at the switch stack and IGMP Snooping is configured (multicast devices are all plugged into a switch that’s part of a stack).
@tom-elliott “So in Multicast, a single file is just opened and sent across the network. Speeds are usually abysmal because the traffic across the switch is just flodded.” - This sounds like a description of broadcasting which goes out to all network devices.
My understanding of multicast is traffic is only sent out to a “select” group of devices; those requesting the data. Why then would that flood the switch? Sorry, its been 6 years since I went to school for Cisco; I need to freshen up and re-educate myself.
