January 6, 20233 yr This has been an ongoing issue that has gotten worse with 6.11.X Every couple of days\weeks my NVMe drive will lose its connection with unRAID. Docker service stops, VMs stop, shares and GUI still work I have to reseat the drive before it is recognized by unRAID after a restart. Because of this the array never fully stops, so upon restart it does a parity check which takes about a day to run with 14TB parity drives Any help is appreciated...diagnostics attached tesseract-diagnostics-20230106-1721.zip

January 7, 20233 yr Community Expert Solution This can sometimes help, on the main GUI page click on the flash drive, scroll down to "Syslinux Configuration", make sure it's set to "menu view" (top right) and add this to your default boot option, after "append initrd=/bzroot": nvme_core.default_ps_max_latency_us=0 pcie_aspm=off e.g.: append initrd=/bzroot nvme_core.default_ps_max_latency_us=0 pcie_aspm=off Reboot and see if it makes a difference. 10 hours ago, Alchemist Zim said: I have to reseat the drive before it is recognized by unRAID after a restart. Most likely just power cycling the server will bring it back, just a reboot usually won't.

January 20, 20233 yr Author adding nvme_core.default_ps_max_latency_us=0 pcie_aspm=off seems to have fixed it been up for a week with no issues Thanks
