Here you can find patches with changes to gmirror(8) and graid3(8):
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
- 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
Because of locking changes it will be really good if you can turn on
INVARIANTS, INVARIANT_SUPPORT options and eventually DIAGNOSTIC in your
Thanks in advance!
