I tested fstrim without mdraid(https://bugzilla.redhat.com/show_bug.cgi?id=837097) on 2.6.32-279.14.1.el6 RHEL6.3 kernel
but I get the following error: - FITRIM ioctl failed: Operation not supported.
I find this bug reports: (https://bugzilla.redhat.com/buglist.cgi?quicksearch=fstrim)
May be it will be closed in RHEL6.4 and I have is to wait and use this release for discard/trim?

Im trying with latest 2.6.32-279.11.1.el6 RHEL6.3 kernel but still no luck - FITRIM ioctl failed: Operation not supported.Is there any way to discard/trim unused blocks with RHEL6.3?What happens if no cleanup is done and blocks count reaches 100%?Regards,
