Hi,

so I moved my plex SSD from an unassigned device to a cache pool a couple of weeks ago, I've had these issues before as well where the SSD would just go missing, now that I've moved it to the new cache pool it'll become inaccessible from time to time. 

 

A quick array stop and start fixes the issue but I would like it to be resolved... I have tailed syslog though I wanted to confirm that it is safe to post it here? 

 

Thank you all!

Problem is not just the SSD, there are multiple timeout errors with various devices, also some read errors with e.g. disk3, this is usually a power/connection problem, could also be an enclosure/backplane issue.

Yes I know, HDD 3 and some others have been giving some errors as of lately although SMART displays no errors for them I just thought they were at the end of their life as those were my first drives I bought used a couple of years ago... Plan on replacing them anyways...
 

If problems for disk 3 keep happening after replacing I will come back to this. Though I really want to get the plex SSD sorted...

Like mentioned it doesn't look like the devices are the problem.

Oh for the SSD as well... So what's the next thing to troubleshoot now? Try putting it somewhere else on the backplane, switching power cords, etc.?

Check connections. If possible, change cables.

Make sure you do not use too many drives on one power lead for example.
