Here you can find patches with changes to gmirror(8) and graid3(8): http://people.freebsd.org/~pjd/patches/gmirror.7.patch http://people.freebsd.org/~pjd/patches/graid3.patch The patches does the following: - Significant synchronization speed improvement. Now many parallel synchronization I/O requests can be used instead of only one before. Many people requested this. - Close race between regular and synchronization requests (I wasn't able to trigger it with one sync request, but with many parallel requests it's real). - Reimplement locking. I moved softc synchronization from the topology lock to per-device sx lock. I'd like to ask gmirror/graid3 users to test those patches as much as possible, because I want to commit them to the HEAD and RELENG_6 branches. Because of locking changes it will be really good if you can turn on INVARIANTS, INVARIANT_SUPPORT options and eventually DIAGNOSTIC in your kernel.
