Hello list, I'm looking for clarification regarding gmirror/geom behavior in current 8-STABLE. I want to use couple of SSD drives in mirror RAID configuration with UFS on top. I know that UFS now supports TRIM (BIO_DELETE) on plain disks. But will gmirror propagate BIO_DELETE event to lower driver, so both SSDs will get trimmed when UFS issue this command? -- Best regards, Dmitry Zamaruev
