Drives unmounting / remounting, plus lots of read errors

[linusk]

Hi there, 

 

This is my first post in the forums so please let me know if I've missed anything. 

 

I recently ran into an issue where my parity drive appeared with a red cross next to it. The drive seemed to keep unmounting and re-mounting with a different sdx assigned to it. I tried swapping the drive bay it was in and still ran into the same issue. 

 

 

I use a DELL H200 to attach the 4 drives (this model: https://www.ebay.com.au/itm/325566986586) and I tried re-seating it, and that seemed to improve things, the parity drive mounted correctly and it started doing a parity sync. But a couple hours in, I had reports of a bunch of disk errors. 

 

I'm still suspicious it's the DELL H200 as all my cache drives are fine and they're plugged directly into the motherboard. I don't yet know how to read the diagnostics files (or what to look for). But I was looking for help identifying from the logs if it could be a problem with my H200 or if I've got a bunch of bad drives.

 

Thanks!

Log shows errors with disk1, so possibly some power/connection issue, are you using any power splitters?

I am using power splitters, and I probably am on the edge of what the PSU can supply.

I've purchased a new PSU and I'll report back how it goes

I got a new PSU and connected the hard drives to that and everything is working now. Thanks for the help @JorgeB.

Lesson for anyone else that finds this, the HP EliteDesk 800 G3 won't support 4 HDDs and 3 SSDs.
