Hi All,

I'm havening an issue with my server. First my cache drive started going missing, it's a Samsung NVME 980.

I've tried putting it into another slot, then i moved all of my cache onto a spare Samsung NVME 870 Evo. Then i moved the system and docker onto the array and still having the issue. 

Can someone please look at the attached log to determine what my issue is it would be greatly appreciated.

syslog.txt

Syslog is just a few minutes after boot, enable the syslog sever and post that after a crash.

 

Also, make sure this has been taken care of:

Thanks! Lowering the RAM speed seemed to fix the crashing issue.

Unfortunately my NVME drives keep disconnecting, i've tried adding nvme_core.default_ps_max_latency_us=0 pcie_aspm=off.

When i reboot the cache drive shows up as unassigned, but once i mount it the drive will disappear randomly. This happens with both the slots.

Servers been working fine, nothing has changed except an OS update about a week or two before the issue.

 

Try also adding pcie_port_pm=off

syslog.txt

Thanks for the suggestion, but its still doing the same thing

If there's a different m.2 slot try there, also make sure the BIOS is up-to-date, if the same I would recommend getting one from a different model.
