Hi, I am running 6.9.2 and noticed errors in syslog this morning which I think suggest one of mt cache pool drives is misbehaving but there are no errors displayed anywhere, nor any note on that drive - are these just info or should I change this drive?

Looks more like a power/connection problem, also by having the SSDs on the HBA you'll lose trim, suggest swapping them with disks using the onboard SATA ports.

Ahh - OK,

I did read about losing trim but I thought that was related to the devices which allow four drive to user one host port.

Will make some changes,  Thanks!

Can you explain how you determine power issues from logs - what to look for for me please?

I'd like to me able to identify such myself.

The type of error, when it's a media error the error it's usually different, also this:

 

Dec 30 07:44:07 Server kernel: sd 7:0:8:0: Power-on or device reset occurred
