New Revision: 244188
URL: http://svnweb.freebsd.org/changeset/base/244188
Log:
Added vfs.zfs.vdev.trim_on_init sysctl which allows full vdev trim on
initialisation to be enabled (1) / disabled (0) defaults to enabled.
This is useful for devices which have a slow trim speed and are either
new or have otherwise already been wiped e.g. secure erase.
...
+static boolean_t vdev_trim_on_init = B_TRUE;
+SYSCTL_DECL(_vfs_zfs_vdev);>
+SYSCTL_INT(_vfs_zfs_vdev, OID_AUTO, trim_on_init, CTLFLAG_RW,
+ &vdev_trim_on_init, 0, "Enable/disable full vdev trim on initialisation");
I'd also make it loader tunable.
Will look into that, worth doing the other SYSCTL only ones at the same time?
Regards
Steve
