An unofficial chapter of the popular Dull Men's Club.

1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.

There are a number of content specific communities with subject matter experts who can help you.

Some other communities to consider before posting:

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

"Is this the one?"
"Yeah, that's the one."
Yank!

As the last of the servers died with a pathetic beep, I think I heard the poor electrician, still holding the unlabeled end of the rack's power line, invoke the name of Jesus.

(Obviously dramatized, but mostly accurate.)

The virtualization servers came back online with some fuss, but they at least look functional. My tasks for the day are set: wade through about 400 error messages, verify the functionality and integrity of 117 virtual machines, restore backups as needed, and verify the SMART status on every physical hard drive.

(edit 1) High Availability tried to migrate all of one host's VMs to the other, but it isn't worth much if both HA hosts are on the same circuit and die within seconds of each other. Now all but a few VMs are running on a single host.

(edit 2) Some of the PhDs are angry because their long-running ML projects got interrupted. They didn't set up checkpoints or live backups, so entirely their fault.

(edit 3) Five hours later, only one VM needed manual intervention (apart from migrating the VMs back to their original hosts), and all the hard drives are in good condition for their age. This turned out to be a really boring disaster.

Unexpected shutdowns of an entire HA cluster can be fun.

But it “shouldn’t” cause any problems, so mark it down as a test.
