https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D208691 Kirk McKusick <mckusick@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|New |Closed Resolution|--- |Not A Bug --- Comment #4 from Kirk McKusick <mckusick@FreeBSD.org> --- I am closing this bug as it is triggered by disks running in an unreliable mode. As such there is no change called for in the software, though one can legitimately argue that the default should be to configure disks to run with `write cache disabled' so that they will be reliable. FreeBSD ran for a whi= le with this default, but for many disks the performance was abysmal, so the default reverted back to unreliable. Most disks support tag queuing today w= hich does not suffer poor performance from `write cache disabled', so perhaps it= is time to revisit this default. But that is not a topic for this report. --=20 You are receiving this mail because: You are the assignee for the bug.=
