Re: [CentOS] LVM thin volumes fstrim operation not supported

My guess? The passthrough is causing the error when the command passes through to the actual device, which doesn't support Trim. I don't know how it actually works, but you can try to poke it with this stick: copy a large file to this LV. Check the LV with lvdisplay. Delete the file. Fstrim.

Hi All I'm trying to setup my LVM thin pool to support discards so that the pool can reclaim space even if the underlying device doesn't support trim. It is my understanding that all thin pools should support trim even if the underlying device doesn't. (please correct me if I'm wrong here) I

I'm curious as to what exactly you are needing what appears to be a second monitor without an actual second monitor? For what purpose do you think you need such a setup? Maybe there's another method to get what you want if you can give us more detail. On Tue, Jan 19, 2016 at 10:53 AM, Joey
