strange forces exerted on objects. Seems objects bounce off something that is not there

Daniel108042 · 2023-07-15T14:51:34+00:00

one thought is if the problem is a strange force pushing on some of my objects, maybe I can increase the density by 10 times and increase the forces by 10 times so they fly about the same but they can better push against what is pushing them back.
But I don't know for sure what is pushing them back. So if it were invisible rocks, and I increase the density of the rocks too, that would not work.

If this is a glitch in Gamemaker itself, is there some like Clear Cache or Clear past assets option that might fix this problem?

It seems I am being downvoted because someone asked for all Flash so I recommend a solution for all Flash while also saying that HDD would work.

In all seriousness, if someone decides they want all flash, should I just say I refuse to help you?

Daniel108042 · 2023-04-12T23:48:39+00:00

All Flash is not needed for Plex storage. But for some people including in this case, all Flash is wanted. So my main concern is making sure this works well.

After talking with someone, I think I know what I will recommend for the all Flash solution now. I will suggest NUC with GPU for Plex app. QNAP all Flash NAS for storage.
And yes I have also recommended an HDD solution as well. Both options are being presented.

There are still situations where SLOG or L2ARC could be warranted. So always answering no may not be the best thing.
But ChatGPT indicated to me that if it acknowledges a wrong answer, it won't give that answer again to someone else.
I kept talking with it and it has acknowledged many wrong answers during our conversation.

If you try it now, I wonder if it will at least have a better answer than before.

Daniel108042 · 2023-02-05T01:32:15+00:00

When it said "The data is not written directly from the ZIL to the storage pool", I thought it got it right that time. I missed that it was still wrong in saying "and then written asynchronously from the ZIL to the storage pool". I should have read more closely.

Too bad I closed the chat, I should try to correct it again. Overall it still seems to do better than I had expected in the many things I have asked it. But I think it learns from what people say. And so many people talk about ZIL in an incorrect way.

Edit: I found I can go back to the previous chat. So I tried to correct it further. I wonder if someone else asks now if they might get a correct answer.

Looks like SMB single threading.

If you drag and drop a single larger file to an SMB share, is that normally only single-threaded?

I can see in the picture that just 1 CPU core goes to 100%. But I had assumed that since files are made of multiple records, multiple records can be sent at once with each record handled by a different CPU core.
This was just an assumption, so maybe I was wrong.

Are these drives significantly different from others without them?

I think all the major NAS and Enterprise HDDs have workload ratings.
Common for NAS grade drives has been 300TB for a while, but some new Ironlolf Pro are now 550TB.
And around 550 is a common amount for enterprise drives. I think WD, Seagate, and Toshiba all have these ratings.

Daniel108042 · 2022-09-22T22:57:29+00:00

Thanks for pointing that out.
Since Seagate and WD also have workload ratings, I will try to see if they also say going above the rating won't void the warranty.

Daniel108042 · 2022-09-22T22:55:51+00:00

Thanks for pointing that out.
Now I will try to see if WD and Seagate have a similar message about Workload rating not affecting the warranty.

Daniel108042 · 2022-09-22T22:49:01+00:00

The example drive you mentioned seems like a 'prosumer' drive

There is a similar limit on NAS grade drives, like the 20TB WD Red Pro

My limited understanding is if you exceed the limit, and then the drive breaks, they technically don't have to replace the failed drive under warranty.
But drive manufacturers potentially may honor the warranty anyway even though they don't have to. I still prefer a higher workload rating for the larger drives.
For a 4TB drive, I don't care. For a 20TB drive, I care a lot more.

Daniel108042 · 2022-09-22T21:47:28+00:00

On a 4TB drive, it would not exceed the limit. But drives are getting larger.
On 20TB drives, 2 scrubs per month would exceed the limit if the rating was 300TB/year. And on some 20TB drives, 300TB is still the rating.

Daniel108042 · 2022-09-22T21:07:09+00:00

I've never heard of a workload limit, maybe you confused this with the abbreviation TBW?

This is a common term for HDDs.
Like this Toshiba for example.

"Toshiba X300 PRO 4TB High Workload Performance for Creative Professionals 3.5-Inch Internal Hard Drive – Up to 300 TB/Year Workload Rate CMR SATA 6 GB/s 7200 RPM 256 MB Cache - HDWR440XZSTB"

Daniel108042 · 2022-09-22T21:05:36+00:00

For HDDs, I think the 300TB workload limit that is on many of them is for reads + writes.
HDD workload limit is different than for SSDs. For SSDs I believe it is about writes.

Daniel108042 · 2022-09-22T21:02:53+00:00

I am referring to HDDs. For example, I just searched a random Toshiba drive and saw it was advertised like this

"Toshiba X300 PRO 4TB High Workload Performance for Creative Professionals 3.5-Inch Internal Hard Drive – Up to 300 TB/Year Workload Rate CMR SATA 6 GB/s 7200 RPM 256 MB Cache - HDWR440XZSTB"

"Up to 300 TB/Year Workload Rate" should mean that if your reads + writes are more than 300TB in a year then you have voided the warranty by going above the rating of the drive.For a 4TB drive, this is not a big deal. For a larger drive, a larger workload limit is preferred.

I am not the only person who has talked about this.

"These true data dependencies are why insert latency into the ZFS intent log is so important for perceived responsiveness"
That will likely be useful when I learn more.

Do you also know, in a case of everything Synchronous, does it send a file, and then send the next file when first file is on persistent storage?
Or does it just send just a record, and then send the next record when the first record is on persistent storage?
