After making the trimming adjustments yesterday still getting cpu_iowait warnings.

Okay here is a refence shot of my Unraid:

Thanks. Okay this is my adjustments:

Okay How do make adjustments to drive trimming ? Any information you could provide? Also, I read where Samsung drives need to be reformatted for a different starting bit for Samsung drives. I have used hard drive utilities in the past to partition etc. . Do I need to use some software like that to prep the Samsung drives? Do you know the steps I need to take?

I have exhausted trying things that I have discovered with the help of the forum. My Unraid server had been running good for three months. At the present time it is not stable enough to run Plex with out crashing or not functioning al at all. What are so basic steps I can take to start over? I thinking of cause use my flash and slowly add hardware back one step at a time. Hopefully, I will be able to get my Unraid server back running.
Any help with steps or guides on how to start over with an unstable Unraid server from scratch.

Still researching information on cpu_iowait and troubleshooting my unraid server issues. Attached a diagnostic file and screen capture. from Glances.
Also, netdata information
Any help will be greatly appreciated.

Unsuccessful so far in finding the issue that causing my URAID/ Plex server to be so unstable. I had a few months of Plex server running great. Now, I thinking maybe I will have to start over from the beginning. Reading and trying a few things and wondering how it could have gone so wrong . Only if I could decipher the critical warnings better. Making list of things to try and crossing them off my list. Wish me luck and will need it for sure.

Well I started my journey with UNRAID at 6.8.x. I am at version 6.9.2 right now. What steps do I need to take to have my Samsung's drives (SSD & Samsung 970_EVO) to start at sector 64? Any help would be appreciated. My Plex is is not stable. I been reading about formatting drives, which is understandably a needed step. Most of the comments assumed the reader was familiar with the process and/or UNRAID. Just need some help to achieve the end result of starting at sector 64 that hopefully will resolve this issue.
I hope that I can achieve some successful help from the community. Thanks in advance.

Just been trying a few things to resolve this issue. My Plex output is not stable getting snow filled video, replaying video and freezing. I pinned CPU to 5 cores and notice CPU_IOWAIT has reduced to 2 entries:

I am fairly new to UNRAID and learning how to troubleshoot and resolve some issues. How can I determine what the bottleneck is via the data I supplied. Could recommend some steps to troubleshoot this issue?

I have the following CPU_IOWAIT errors on my UNRAID:
I have research this error a little and there is some older information available with maybe issues with older versions of UNRAID. Some discussions related to Mover and/or Samsung drives starting at a different location causing a delay of data transfer (not very clear). Is there a definitive answer or maybe a guide to solve the problem?
-
No. I have not found any solution for the problem.

Question, will one Plex docker over another Plex docker give one less reads and writes. I just setting up my server and wanted to know the best Plex docker to use. I been reading some older information and wanted to setup a current Plex Server docker that runs with little reads and writes when there is no Plex user activity. Any help would be appreciated.
-
I have other dockers installed but only have Plex started. When I stop Plex the reads and writes are at a normal rate.
-
I have a fairly new Unraid system setup with Plex (plexinc) docker. When plex is started and no user activity the server gets large amount of reads and writes over a short period of time. There is no user activity at the time. I am running Unraid 6.9.2. I been reading some similar issues that were resolve with 6.9. Also, in other issues the docker needed to be replaced with another Plex docker created by Linuxserver. Any help with be appreciated. I am fairly new to Unraid.
Any Current Solutions For Critical on CPU_IOWAIT Errors On UNRAID System ?
