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 initial learning curve, dare I say, even a joy t

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 that is stored in RAM. It's great! Previously, if I

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 typical Leaf-Spine network architecture, you can easily have su

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 installation is pretty big and used to support critical

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 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 around the same time I ordered it I had one of these clot

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 have 10 nodes, yeah then maybe that's a good rule of

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 could look into reducing the latency of your status page. By

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 that either. Homelabbers maybe, but then why are you compar

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 cheapest cameras ended up serving my needs the best. I

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 pressure in general, and depending on your workload and other

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 cluster is running on some 7 Raspberry Pis currently,

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 million objects in a single bucket, but other than th

Not sure if I agree with you on RAID 0, but RAID 1 certainly is, and that's indeed what I'm running. The 3x20TB btrfs setup I mentioned is configured with RAID1C3 for metadata, and RAID1 for data, and works just fine with even or

In case you ever have to work with a directory that has lots of files in it, sometimes it's useful to remember the -U flag in ls. For example to count the number of files, I sometimes use this: ls -U1 |wc -l Can be very fast wi

I am honestly curious, what do you run on your server that you can't connect to with Tailscale?
