I/O request timeouts on RHEL 7.5 with Intel P4500/P4510 NVME drives

WEvan3 — Thu, 27 Dec 2018 04:39:58 GMT

Hello,

We are experiencing persistent I/O request timeouts on Linux with P4500/P4510 NVME drives.

The systems we are experiencing these request timeouts on are RHEL 7.5. The kernel version is 3.10.0-957.1.3.el7.x86_64.

The P4500 drives are on firmware version DV10170.

The P4510 drives are on firmware version VDV10131.

Both systems have 15 drives; one has 10 P4500 drives and 5 P4510 drives, and the other has 15 P4510 drives.

This is the output of one of the drives; all drives are showing these errors:

nvme nvme14: I/O 487 QID 83 timeout, aborting

nvme nvme14: Abort status: 0x0

nvme nvme14: I/O 487 QID 83 timeout, reset controller

INFO: task dmcrypt_write:2573 blocked for more than 120 seconds.

"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Attached is the output of ssu.sh on the system with 10 P4500 and 5 P4510 drives.

Josh,

They did not; all NVME drives were purchased separately.

Thanks!
