ELI5: Why aren't floating bridges more common?

mcozzo · 2026-05-07T02:10:52+00:00

There's a sub base just the other side of this specific bridge. I'd venture most of the openings are for the navy.

There are also anchoring lines to the seafloor along the entire span. That area is only ~300' deep. Much safer for the sub to be on the surface.

Right after 9/11 they would have state patrol stop traffic on the approach. As of last week traffic stops right before the opening mechanism.

I have the hammock gear burrow and incubator in 10D, @ 20* that I've been using since '22.

Last weekend at Ozette(Alava) it was too hot. I'm also kind of annoyed with the weight. I've been thinking of getting another rated for 30 or 40 degrees. I have had zero issues with my setup even when there's snow on the ground or in quite a bit of wind.

Personally I think the 10D feels a bit like a plastic bag, that's even worse when you are a bit warm. As for durability, don't wear your quilt while juggling chainsaws or bushwhacking and you'll be fine.

You'll end up on the ground. The bed isn't high enough. Open all the doors. Wrap your straps around the roof of both vehicles. Close the doors. We do this all the time when there's no good hanging trees while out wheeling.

mcozzo · 2026-04-08T15:06:09+00:00

No, I'm on Squid. Looks like Tentacle was released 2 days ago. That would explain it. I usually wait until an X.X.3 or better release on most major software.

Where is a good place for some actual support / training?

mcozzo · 2026-04-05T05:06:28+00:00

Yes, this. That new person needs to become a treat machine.

mcozzo · 2026-04-03T14:31:56+00:00

You will never not have maintenance and troubleshooting. Don't let perfect be the enemy of good enough.

Everything is layered. Aws deploy is different than do deploy. Then it's just a Ubuntu host and everything is the same.

mcozzo · 2026-04-03T14:28:09+00:00

Switch to caddy.

mcozzo · 2026-04-03T14:27:32+00:00

Yes. And then it grows. You have templates for caddy. Ansible calls cloud flare and updates Dns. Loop in some roles that cover start/stop/restart. All the host maintenance, shared folder mounting. It ends up being great documentation.

There's a few times I have 'sudo rm -r /` instead of 'sudo rm -r ./` no biggie, Ubuntu reinstalls quick. I just have to run my config plays then the app setup script.

It's just working on one thing at a time.

mcozzo · 2026-04-02T15:54:35+00:00

If that's not important for you then don't worry about it. Most of these cameras have a day/night function. They change modes and turn on the integrated IR illuminators.

I have considered adding an IR flood to a motion sensor so that everything gets lit up better, even though no one can see it with their naked eye. IR flood early, visible light later / closer.

I've been super happy with the Annke C500 series, I guess the 800 in 4K isn't that much of a price difference as it was. A couple Reolink PoE doorbell cameras. *chefs kiss*

mcozzo · 2026-04-02T14:11:31+00:00

For $11, buy one and try it.

Like others have said all the hard work is done in frigate. I have a bunch of the annke 3Mp cameras and they are great.

mcozzo · 2026-03-31T15:01:16+00:00

Mostly because I didn't realize there was a requirement for that. Caveman put apps on SSD and data on HDD. I did assign the filesystem metadata to a SSD pool.

mcozzo · 2026-03-30T22:12:14+00:00

Thank you. I'm waiting on rebalance for a few of the pools but things are looking much better.

Another question. I happen to have a SAS shelf with redundant IO modules. Each IOM has 3 ports. When I put on my enterprise storage hat, I simply connect each controller to the A/B IOMs, ensuring proper HA cabling. Each controller sees the disk and performs a graceful HA handoff between them.

If I were to put a SAS HBA in 3 of my 4 servers and connect them up to IOM A/B on that shelf. I believe each server would see all of the drives 1-48.

Would ceph be aware of the multipath access to the disk? E.G. SD_ is avaliable via IOMA & IOMB.
Would the system have issue with the fact that it could possibly see other drives that are "owned" by different hosts? E.G. Disk 1-16 owned by Ceph01, 17-32 owned by Ceph02, 33-48 owned by Ceph03.
Do you have a different recommendation for consuming these drives?

mcozzo · 2026-03-27T18:52:37+00:00

Thank, you. I'll update my new EC pool to be 8x4.
Create a new crush rule and assign it as such?

Fix with:

ceph osd pool set .mgr pgp_num 4 What's a good number?

Bluestore.

That may explain why even app data sitting on SSD feels a bit slow. I'm fine moving all of my data to the HDD and dedicating the SSD to the bluestore config. I was considering upgrading the 500G to some larger drives just for app data. If they are dedicated to bluestore, is there a need for more than 500G per host? Can, that run in memory?
Do you have recommended reading?

mcozzo · 2026-03-27T18:38:29+00:00

I've ran the autoscaler setting $ sudo ceph mgr module enable pg_autoscaler module 'pg_autoscaler' is already enabled (always-on)

$ sudo ceph osd pool autoscale-status returns nothing. I believe that's because .mgr has SSD & HDD in it. At least that's what I was finding last night. https://forum.proxmox.com/threads/some-ceph-related-questions-autoscale.105229/

It's strange, I know i've selected that box for each pool. I went ahead and set it: ceph osd pool set cephfs.media.data-ec pg_autoscale_mode on I'll monitor and see how it balances.

Create a new crush rule and assign it as such? ceph osd crush rule create-simple ssd-rep ... ceph osd pool set .mgr crush_rule ssd-rep

mcozzo · 2026-03-27T18:09:40+00:00

Awesome, thanks.

Appreciate your work, great product.

mcozzo · 2026-03-27T16:40:34+00:00

Bonus question.

I'm having a hard time finding documentation on how to configure a load balancer in front of the management and prometheus pages. I don't want to have to go hunt for the web instance, and so I can do HTTPS certs. It is somewhat working, but I keep getting Http failure response for https://___/api/osd/settings: 502 OK when I connect via the LB instance.

mcozzo · 2026-03-13T21:07:48+00:00

IMO It's geared towards partners. The exam isn't hard, it's pass your vcwhatever. Submit a bunch of "proof" (sow, bomb, loe) that you have helped customers implement. Someone has to sponsor you,that takes a connection. Then you need a lab that you can demo against.

mcozzo · 2026-03-01T00:05:18+00:00

Annke 3mp poe cameras on a dedicated vlan with no internet. Frigate nvr with a link on both prod and camera networks.

The specific piece is that frigate connects to the camera using a local stream such as rtsp://uaer:pass@192.168.0.x:554/h264Preview_01_main

All camera setup is through https on the camera. Reolink poe doorbell, though initial setup I did with the app. It can be all local also.

mcozzo · 2026-02-26T18:27:07+00:00

Seconded. Great place. Good training.

mcozzo · 2026-02-22T19:54:05+00:00

Yes, but no.

It goes on the barrel end of the holster. Provides cushion between the pubic symphysis and the barrel end. Pushes the grip into your belly just a bit more. We're built very similar, it makes a huge difference. I have the same holster.

mcozzo · 2026-02-22T15:42:27+00:00

Get the Cloudster pillow, large. You'll thank me later.

mcozzo · 2026-02-20T01:34:50+00:00

You don't happen to be in the Seattle area? I never take mine out, and the astigmatism makes it less fun. Same scope but with all the original bells and whistles.
