As someone who's in charge of close to an exabyte on Ceph, I couldn't disagree with you more. Done correctly, Ceph is extremely reliable, resilient, and fast. Once you get over the…

I think more people should know about the existence of ZRAM on modern Linux distributions. It's really changed the way I look at swap configs. ZRAM is a compressed block device tha…

Make sure you have solid Linux system monitoring in general. About 50% of running Ceph successfully at scale is just basic, solid system monitoring and alerting.

Not sure what you mean about Ceph wanting to be in a single rack. I run Ceph at work. We have some clusters spanning 20 racks in a network fabric that has over 100 racks. In a typi…

Monash University is also a Ceph Foundation member. They've been active in the Ceph community for a long time. I don't know any specifics, but I'm pretty sure their Ceph installati…

What did the provider do? Did they put your IMEI onto some list of other customers that complained, where all of you get better network prioritization? I'm genuinely curious.

I've lived most of my adult life in houses with forced air furnaces (albeit powered via natural gas, not propane), and what you are saying is inaccurate regarding indoor air pollut…

I know I'm going to sound crazy here, but there is one more alternative. How about: Reduce, Reuse, Repair, Recycle? I recently got a sewing machine for an unrelated project and aro…

While most of what you speak of re Ceph is correct, I want to strongly disagree with your view of not filling up Ceph above 66%. It really depends on implementation details. If you…

Thank you for this detailed reply! I only want to add a small suggestion. I get that large distributed production systems will occasionally go down, but it would be great if you co…

I opened a support case at 9:04 AM EDT. So far, no response yet.

Having the same problems. It started out as not being able to search, but the situation is quickly deteriorating and now I'm unable to open pretty much any email message. Some cont…

Because you need to know who is logging in before you know what IP policy to enforce, no?

Distro: Fedora (default Gnome) Laptop: LG Gram 16" There are several variations of the laptop with spec differences, the main thing you want is Intel CPU with integrated graphics. …

The way it looks reminds me of the Handspring Visor[1] for some reason (with less buttons). 1: https://en.m.wikipedia.org/wiki/Handspring,_Inc .

This is complete nonsense. No one running business critical installs of Ceph runs single-monitor. You can also tell Ceph to use a single disk as your failure domain. No one does th…

I had to get a new setup spun up very quickly, didn't know what to get, so I went out and got a bunch of cameras ranging from $49 to $500 from MicroCenter. For my requirements the …

Ceph actually works very well with swap on zram. I have some older Ceph clusters that have 48GB zram devices used for swap. It sometimes helps with defragmenting memory, memory pre…

CephFS works great at home. I've got an all-Linux setup, and it works great on Laptops as they go to sleep and resume. Works great over Tailscale on a modile hotspot too. My home c…

You're mixing software defined storage options with public cloud offerings, which is kind of strange. If you have your own hardware, Ceph is solid. I wouldn't put more than 200 mil…

Makes sense. I should have read your comment more carefully! :)
