So the follow up to my rant below - I need a way to generate 14TB of uncompressable data and see what happens.
You can use FIO to generate multiple 1GB unique files if you'd like and stream them to the OneBlox Ring. This is what we do internally to test and fill up our file system to 100% utilization in our QA process.
-
Seems like the errors from last week have gotten strange. I've only been loading data to the "victoria' unit, however the "vanouver" one is showing greater storage used, along with a really sweet amount of dedupe
-
Have not yet contacted support as I suspect this may be related to the really crappy networking I gave it. I will let it sit and stew for another day as I have no time to poke it today.
-
Connected the delinquent "vancouver" one back up to clean 100mbit lan, will see if anything changes.
-
Note: all errors mentioned below still exist on the "vancouver" unit as I post this, including wacky dedupe ratio, 100GB greater capacity in use and file system inconsistency error
-
Time to get support to take a gander, I would say.
-
@scottalanmiller I'll give it 24h to sort it's self out - if it was the hub, that'll give it time to heal. I really don't expect anyone's tested it with such poor networking gear and while I didn't expect it to cause issues, it's outside of what I'd expect them to support.
-
@MattSpeller No, that is exactly what you are paying for. make use of it. By not contacting support you are wasting time and money.
-
@JaredBusch If it was in production, 100% agree. I unfortunately don't have time to poke at it today so I'll let it sit.

support will be reaching out to you to look at the secondary. Better to be proactive than reactive

You'll see really good dedupe ratios like this as it's strictly a calculation based on how much data is written the Ring and then to the physical drives. Over the week and lifetime you'll get a more 'reasonable' ratio

Contact established with Support at 1:30pm, email at 4:42pm requesting permission to reboot, I replied immediately, box rebooted at 4:46 with all errors cleared. I'm a happy camper.
-
So, error came back maybe 30 minutes after it was cleared. I rebooted the unit again and it seems to be gone for good. Support reached out to me again and suggested I run the software upgrade they released - it's now underway on both.
-
Cool, thanks for all of the feedback.
-
@scottalanmiller Helps me later when I go to write it up for the boss

An interesting find developed over the long weekend. The troubled oneblox unit finally stopped talking some time friday evening. I came in this morning and traced it down to a faulty ethernet cable. How much this has contributed to it's chain of errors is unknown, and I am happy to give it the benefit of the doubt moving forwards.
-
To speed up testing I've installed a gigabit switch, this absolutely will change their performance.

Welcome to 2003.

Having some further errors on the oneblox units, apparently they're not talking to each other right now. While I find this slightly irritating I want to point out the following email chain, check out the times.
