That's bad software then, right? The inability to write to disk shouldn't cause the software to lose all functionality. Unless that's its only function, or somehow depends on it for proper functioning. 🤷♂️
No. Every good software program should write at least logs to disk. Every good database writes to disk. Add a new post, db will commit to the db and the db will grow in size.
Name any decent sized program where new content is added and I guarantee it writes to disk and will fail eventually if not maintained.
Nice down vote. Let's discuss instead.
I'm saying that the server shouldn't go down just because new content can't be added. You should get maybe a 500-series REST response or something. Not... nothing. Ideally it should write to disk. Ideally it should allow new content to be added. But uptime and content access is still more important than being able to write to disk. It should warn the admin of the serious errors, and explain to the user in some diplomatic/apologetic manner. But never go down completely. That's not resilient at all.
That's my opinion. 👍
For the record I did not downvote.
But I capitulate on your point. It would be great if every piece of software was written with resilience and uptime in mind.
As a former sysadmin that sounds like a dream. But I don’t think I have ever seen that with any mainstream program that I’ve had responsibility for. Does that mean all those programs were bad? I don’t think so. We wouldn’t need sysadmins if all programs were written the way you describe.
Programs can be written to auto rotate their logs, compact and reindex their db’s. Using browser updates as an example, they can even safely auto update and revert back on failure.
How many programs actually do these things? My experience is next to 0. But I wouldn’t call them all bad or poorly written programs.
Thank you. It's alright, just aimed at whoever did. Sorry if it came off salty!
I meeeaaan... I hear what you're saying. I think your definition of "bad" is a bit stricter than what I was going for. So, you're right. They're not bad in some sense that they're useless or something along those lines. But if I were to write server software, my main goals I guess would be security, performance, and resiliency to failure. Stay alive at all costs (within reason).
But I think we're both on the same side there on all counts. 😁👍
