Cant Manually Enter Clients / Drive Spin (constant)

[dureal99d]

Ubuntu 16.04.3
Fog RC-8
Dual Qaud Dell 16 gigs ECC

I have a fog server that i have been running for quite a while now.

I notice that this morning the drive that serves out images has been spinning up for about 16 hours now.

I also notice that I cannot enter New Clients Manually.

Any Ideas???

What do you mean by that? Is it an external USB drive?

[dureal99d]

@sebastian-roth Right!! All my drives are internal. and by spinning up meaning that the drives are never idle and ill post a screen shot later with iotop data

[Sebastian Roth]

@dureal99d Is it just one single FOG server or do you have storage nodes as well? Maybe image replication is going on? Other than that I wouldn’t know what should be writing/reading to/from the images directory all the time.

[dureal99d]

@sebastian-roth 1 server. no nodes.

@sebastian-roth image replication acting up constant read to www-data. How does one fix?

@dureal99d How many fog clients are in your environment approximately?

[dureal99d]

@wayne-workman Roughly 30-35

@wayne-workman I had this happen one other time in fog it turns out it was something to do with fog and tom Elliott fixed it. So i figure it must be something in this newest revision of fog acting up again in this case perhaps the same thing or a different thing affecting the image replicator.

@dureal99d Can you give us a screenshot of some output from the top command please, and make the picture so it’s focused and a glare isn’t covering it, and close up enough that we can read it.

[dureal99d]

@wayne-workman yes give me 2 hours

[dureal99d]

@wayne-workman Clearly i took more than 2 hours However
just look at the very top!!!

@dureal99d If this really is your only fog server, you can just disable the fog image replicator and the problem should go away:

systemctl stop FOGImageReplicator
systemctl disable FOGImageReplicator

[dureal99d]

@wayne-workman ok I’ll try this command.

systemctl disable FOGImageReplicator

Thanks that fixed it!!! What does the image replicator do or rather what does disabling this module affect?

It does exactly what the name suggests… It replicates (copies forth and back) images between different nodes. You don’t need this in your setup. So disabling should be fine. Just keep that in mind for the next upgrade or if you wanna extend your FOG setup and add another node.

@sebastian-roth I see, also i am now able to manually enter clients. This thread is solved. Though i hope the next update fixes this issue.
