nvme0n1p7.blktrace.0.txt.tar.zst https://drive.google.com/open?id=1IKS6_4Kij1dcRqAezTqMfUwMDggtnrmD I'm not sure whether this NVMe drive supports queued trim, or if it's intentionally slow to avoid the pausing problems seen on non-queued trim drives? I'm offhand not experiencing any hangs while issuing this trim, including scrubbing this file system while trimming it (seems ill advised, but I like misery). However I do get a circular lock warning... Chris Murphy
