https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241980 --- Comment #25 from Andriy Gapon <avg@FreeBSD.org> --- (In reply to Eugene Grosbein from comment #23) So, I am not sure what this tells us. An I/O request taking tens of minutes does not look normal to me, even if i= t's a TRIM request. Maybe disable the deadman logic, maybe disable ZFS TRIM. Or maybe there is something special about the SSDs or something that can be tuned. But this does not look like a problem with "core" ZFS. I think that Warner Losh looked deeply into the SSD/TRIM situation, maybe he can give some additional ideas. --=20 You are receiving this mail because: You are the assignee for the bug.=
