I just recently enabled trim for my SSD + zpool: /boot/loader.conf => vfs.zfs.trim_disable=0 The SSD hosts root zpool, plus ZIL of second pool hosted on spindle HDD. Previously I was using the configuration without trim code in loader.conf. sysctl kstat.zfs.misc.zio_trim shows: kstat.zfs.misc.zio_trim.unsupported: 106 kstat.zfs.misc.zio_trim.failed: 0 2 questions: * What does the *trim.unsupported* mean for my setup * Do I need to run code to fix this (like zpool clean zil) in single-user mode? Thank you. ----- FreeBSD-11-current_amd64_root-on-zfs_RadeonKMS -- View this message in context: http://freebsd.1045724.n5.nabble.com/ZFS-Trim-tp5864731.html Sent from the freebsd-fs mailing list archive at Nabble.com.
