BTW, there was a post on the XenServer forums about running off of USB today, and this was the response (from a user with almost 6,000 posts there):

"Its technically possible, but frowned upon due to SD cards usually not being good quality that can handle the amount of read/writes. There are sites/link on the Internet where others have done such a thing. Citrix will likely not be of assistance if you need there support, you would be totally on your own."

https://discussions.citrix.com/topic/380868-hypervisor-on-sd-card/
This thread mentions that Citrix will not "support" external logging, is that an issue to be concerned with?

It's an issue if you want to send your logs in to be analyzed by Citrix.

@FATeknollogee If you have bought support from Citrix it will be an issue, if you are the one providing the support as with any other linux install it will not.

IE: If you're paying citrix for support, follow their guide on installation, use hardware raid, and create two partitions. One for XS, the other for your VMs.

Well, that's the main issue I am trying to get to the bottom of.

ML loves USB installs, but is it the right call?

Plus, at least on a DELL array, you'd have to install XS, then add SR via console later. They don't let you set up partitions during the install.

FATeknollogee

Nah, I'm supported by the People's Republic of ML...

BRRABill

Wasn't the XS logging. I pointed it at my Splunk install and it immediately worked.

So something in Graylog broke.

I wonder what...

BRRABill

Still nothing being written.

(At least in /var/log)

So, it actually worked!

Is there an easy way in Linux to see what files have been written to today?

You could do a find at the root level

find / -path /proc -prune -o -type f -mtime -1

That searches for all files modified in less than a day excluding the /proc directory.

Holy cow that listed a LOT of files.

You rebooted this morning. That would be pretty normal.

Yeah that's what I was thinking (hoping?) ...

I'll run it again tomorrow and see...

Another quick Linux question...

How does one create a file out of that? It went too far for my Putty window to handle.

pipe it to a file >> files.txt

@BRRABill

It should be as simple as

 find / -path /proc -prune -o -type f -mtime -1 > output.txt

What log server are you using to collect the logs?

What changes did you make to the config file for the logs?

I was using Graylog, which was working before. However now it is NOT working.

Trying to reinstall GrayLog.

I figured out why Graylog wasn't "working".

It installs with a timezone of straight UTC. I set my timezone to America/New_York and rebooted. And VOILA! It is now working again.
