I saw discard timeout on HGST 1.6TB NVMe, not sure if yours is same with
that one.
Could you collect logs via the following steps?
Suppose your nvme disk name is /dev/nvme0n1:
1) queue limits log:
#(cd /sys/block/nvme0n1/queue && find . -type f -exec grep -aH . {} \;)
2) NVMe IO trace
- enable nvme IO trace before running fstrim:
#echo 1 > /sys/kernel/debug/tracing/events/nvme_setup_cmd/enable
#echo 1 > /sys/kernel/debug/tracing/events/nvme_complete_rq/enable
- run fstrim
- after the fstrim failure is triggered, disable the nvme io trace & post the
log:
#echo 0 > /sys/kernel/debug/tracing/events/nvme_setup_cmd/enable
#echo 0 > /sys/kernel/debug/tracing/events/nvme_complete_rq/enable
#cp /sys/kernel/debug/tracing/trace /root/nvme_io_trace.log
thanks,
