Hey everyone. I've tried what I could for the past week from searching through the forums and now I am reaching out for specific help.  I've learned a lot in the past week of what I have been doing wrong with my Unraid setup and since then I've been trying to resolve the issues I made in  the beginning. My current task is swapping out all SSDs that are in my array with HDDs. I stupidly thought SSDs would be better not seeing that they were not supported within the actual array.... So, I have been swapping out drives the past week-ish and I am currently rebuilding Disk7 but during the rebuild I am getting a ridiculous amount of read errors from Disk8 even though it shows as healthy and passes all SMART tests. I was able to copy all data from Disk8 to other drives in the array so I am ok with removing Disk8 from the array.

 

After I copied all the data from Disk8 I tried the rebuild on Disk7 again and still got the read errors for Disk8. I then tried moving all the data from Disk7 to Disk10 which has enough space available but almost instantly got the read errors again on Disk8. I would've thought that wouldn't happen since I was only moving from DIsk7 to Disk10 but I guess there  are other things going on I am not aware of.

 

My question here is, can I remove Disk8 from the array while Disk7 is in the rebuild/emulated mode? I believe if I can remove Disk8 then the rebuild will finish OR I can at least move all the data off Disk7.

 

FYI, there are a few more SSDs I need to swap out and have drives arriving this week to do so. Thank you in advance for any and all help you can give me.

Diags are after a fresh boot, post new ones after the problem.

Sorry about that. Here you go.

 

Also, not sure if this is useful info but if I pause the Rebuild and keep all my docker containers and VMs off, the array stays up fine and I am able to view the media that is stored on it through Plex.

Looks more like a power/connection issue, replace cables (both power and SATA) for disk8 and try again.

So far it looks like you were right (as usual)

 

This Unraid setup was started with extra PC components I had so it doesn't seem like the PSU I have in there is able to handle all the drives, fans, etc. I have a new PSU coming in today to completely confirm that was the issue but just by me shuffling around and removing some of the fans (I was using one of the Molex to SATA PWR adapters...) I have it rebuilding now and it has passed the point it always failed at before so I am hopeful that was my issue all along
