I am using (2) Sabrent 512GB Rocket NVMe PCIe M.2 2280  SSD's for my cache pool.

one of two the NVMe M.2 chips now shows up as "Not Installed "

the server is still up running but I either need to re-seat the chip or replace it, 

I'm looking for recommendations on how to proceed so as I don't create more issues for myself.

I have attached the Diagnostics zip file.

thank you in advance for your support.

Looks like it dropped some time ago and the syslog doesn't show the start of the problem, rebooting should bring it online, if yes you should then run a scrub, see here for more details, also on how to better monitor the pool.

Thanks for the information, I was able to get the Cache drive back by re-seating it, reboot alone did not do it. 

I am going to try monitoring read/write errors

 

Thanks again.
