City of Arlington did a no-mask fireworks show last night apparently. Which might sound bad, but even in the DFW no one really wants any extra Arlington going on. So not to be morbid, but thinning out the population down there isn't of the greatest concern to the rest of the metroplex, if you know what I mean.

It's clear that areas of more "problems" aren't being told to wear masks like better areas of the city are. Tarrant Co does really want to have to deal with them.

Check my Facebook, hurrah me!

I don't have facebook, what's your link, is it public?

Coffee time.

This is odd, but ML is back to old numbers with like 100K views a day now. Zero idea what caused the traffic to return to those levels.

Hmm something seems fishy there because I noticed on my end there wasnt a single post for an hour or two. Just seems off with that much supposed traffic.

Well view traffic and post traffic have never been linked. If anything, they tend to be inverse.

@Pete-S said in RAID5 SSD Performance Expectations:

Having a drive failure will become such an odd failure like having a raid controller, a motherboard or a CPU fail. You'd just replace it and restore the entire thing from backup.

I think drives already fail less than RAID controllers. From working in giant environmnts, the thing that fails more than mobos or CPUs is RAM. That's the worst one as it does the most damage and is hard to mitigate.

The difference though is that mobo, controllers, PSUs, are stateless to the system but drives are stateful. So their failure has a different type of impact, regardless of frequency.

@Pete-S said in RAID5 SSD Performance Expectations:

Intel was pretty clear already a few years ago that they consider SATA and SAS SSDs to be legacy products.

Yeah, the interface and protocols are totally designed around the needs of spinning platters.

@brandon220 said in RAID5 SSD Performance Expectations:

I was looking at some specs on one of my machines and decided to look at the difference for a SSD and spinner. Pretty interesting... The IOPS difference is more than I would have guessed.

Yes, and if you would've put in a NVMe enterprise SSD in the mix it would have been crazy. Expect 2000-3000MB/sec and 200-600 thousand IOPS - for a single drive.

Yeah, even my desktop drive circa 2014 was getting 50K IOPS.

What SMS settings are required for this. Like... is it GET or POST?

POST.

Thanks.

@jmoore said in Miscellaneous Tech News:

So they had a database seen by everyone?

Yes. MongoDB presents as a web server. So by default, it's just a web server serving up all your data.

Bunch of dumbass people who are setting up servers without any security in place.

It's more than that. It's not a lack of security. It's actively publishing the database publicly!

Exactly, if the DB is running on a server, that server should not be publicly accessible.

Or have no firewall. Or use "bind 0.0.0.0" as the default.

So they had a database seen by everyone? I don't understand. Hardening servers should be your first plan before it even goes active.

Shouldn't need to HARDEN something like that. For some reason, people actually disable their firewalls AND install a database AND set the database to listen publicly, be default!

@JaredBusch said in Show Active Users in NextCloud:

On a related note, Nextcloud still hasn't allowed "stable" to go past 17.

Yeah, I feel like the stable system has been forgotten or something.

@JaredBusch good point, I was thinking signed into the web interface, but that doesn't mean anything, so that wouldn't work. hmmm...

Anyone know of a way to see who are all of the active users on a NextCloud install? Like, not who is looking at a particular file, but just who is signed in and using the NC platform? Just seems like something that would be handy to know and commonly desired. But I don't think that I've ever seen that functionality.

We are on NC19 currently.

@Pete-S said in How can we recover data from Hard Drives were on RAID 10 without controller?:

And I think people are over-consolidating in their excitement to consolidate everything. Basically ending up with all the eggs in one basket.

We see this a lot. There is certainly a desire for "one pool of storage" and it's so easy now that 10TB drives are so cheap. Heck, I bought one for my kids' video games. 10TB Helium 6Gb/s SATA drive with 256MB cache on my children's video game machine!

@Pete-S said in How can we recover data from Hard Drives were on RAID 10 without controller?:

RAID-6 arrays also have a tendency to big large arrays with large drives, exacerbating the problem.

This is a complex logic. It's something like...

Large arrays tend to use spinners. Spinners tend to use RAID 6 or 10. Large arrays tend to be costly for RAID 10. etc.

But a huge selling point for RAID 10 is that recovery time is flat. Keep adding drives, the recovery time doesn't change. RAID 6, every additional drive can add a bit of time.

@Pete-S said in How can we recover data from Hard Drives were on RAID 10 without controller?:

They just pop in the replacement drive and wait. Not knowing that they need to adjust the rebuild priority unless they want to wait forever.

Or.... they should have their rebuild priorities adjusted as a standard based on the assumed workload needs and only adjust later if something special has happened.

@Pete-S said in How can we recover data from Hard Drives were on RAID 10 without controller?:

Yes, and it's the double parity (Q) that is very costly in CPU to calculate. The actual math for the double parity is advanced stuff, way beyond me. But if you have one failed drive you only have to do the double parity calculation every N stripes to be able to rebuild the drive.

Yeah, I was trying to allude to that in what I had said. Only when replacing the P, I think, it needs that.

About to get ready to go to a client site to do some networking work.

We are moving from a pilot of Zabbix on a few hundred machines, to going out to thousands.

@JaredBusch ah, i see it now. Doh.

Classic bias-caused mistake.

Well yes, I'll agree there. But I will say, I'm not the one who made it, that would be the reason that I missed it on verification. It was sent to me. So I had the additional bias of "I was told X" and when I looked it appeared to be true. If I had found the page myself rather than having it interpreted for me maybe I wouldn't have made the mistake.

Welcome to @cregox

Who, like most of you, found his way here because we were arguing about something yesterday

@cregox everyone gets mentioned here eventually!
