Ok so I'm seeing some curious issues with this ceph cluster and either I have a config issue, or a core misunderstanding that I really should address before I build out further

I have 8 hdd disks across 4 nodes, and in rook they're dust assigned to a 4+2 EC pool.

I had thought it would spread […]

All drives have been added physically, now to figure out how the heck I'm going to build the pools and then transfer data over

Current plan:
* I have 8 disks, so I'm thinking 4+2 EC pool with the HDDs only, ODD failure domain because I just don't have enough hosts
* I think I can update Ceph […]

Cluster rebuild project:

This isn't yak shaving, this is something else entirely

The goal: move all bulk storage off of the old NAS and onto a 3.5in HDD Ceph pool in the Minilab (plan is 4 nodes 8 disks 4+2 EC pool with osd failure domain). Most of the bulk data will be in CephFS. I plan to […]

A pair of 12U 10in mini racks showing a switch and router on the left and on the bottom of both racks are 4x servers with pairs of 80mm fans and a 1U drive bay with dual 3.5in hot swap drive bays

Physical test fit is good!

Inne's Minilab is a 92% effective saliva-based contraceptive test that identifies fertile windows by tracking hormonal changes. Not suitable for women with irregular cycles, it may gain new health management features soon.

new switch has arrived early from Lativa and has been configured: :ablobcatbongokeyboard:

should be able to swap this out as the core switch tomorrow (homelab rule: don't do major network upgrades 2hr before move night)

Networking rebuild continues: now hunting for the "core" switch

* refurb TRENDnet 12-Port 10G (TL2-F7120 ) . Way more sfp+ ports than I need, and only supports 1gb/10gb so no ability for using the spare ports as 2.5gbs

* Mickotik CRS310-5G-4S+IN barely enough sfp+ ports, I wish it had one more […]

Cluster Rebuild Project: MiniLab Eddition

The cluster is now entirely* running on the Minilab hardware. Down to 5 talos nodes.

The entire stack including GPU node, and switch weighs in at about ~170W. That is measured from the wall and consists of:

* 4x Odroid H4 Ultra with 32GB RAM, 2x 800GB […]

Brainstorming a bit more on the Minilab power distribution

* I already have what I need for wall power bricks to power things with 3 bricks + splitters
* Fewer than that could be tricky
* I dove into researching various chassis mount PSUs (Mean well LRS-100-12 for example)
* I don't see an […]

Ok looks like all 5 systems+switch is pulling 140W, but nearly 60W is the system with the GPU (and half of that is the GPU itself) so not too bad.

It will creep up a little bit as I move over a few more drives

Getting the whole thing under 200w seems […]

Ok, back to looking at power supplies. Currently power is very not redundant and that makes me feel uneasy when moving from "real" rackmount systems.

The main elements of the rack are:

4x odroid (11-20V)
1x core ultra (12V)

CRS310 (18-57V)
RB5009 […]

ok I found a 3d printed 10in disk shelf that fits 6x 3.5 disks, which would be perfect if I could find a decent mITX board for a nas that checks all my boxes

worker node added and joined to the cluster :neocat_floof:

smart plug says it is using 15W-20W, not bad but we'll have to see how high it can get (I disabled turbo in an attempt to cap power usage, maybe I should do that differently)

Next up:
* Add the […]

Well as expected this is a chaos mes of wires now that I've actually started hooking up power/ethernet and I just don't have the right length cables #Homelab #Minilab
