[DRBD-user] Using flashcache with drbd v8.4.3

Hi -

I tried to upgrade to v8.4.3 which does significantly improve
performance except that when I enable SSD flashcache the IOPS are
dropping to less 30! The SSD model is an Intel DC S3700 (HW RAID1, 3ware
9750).

It works OK with the 8.3.7 version provided in squeeze but I'm actually
concerned to deal with that IO limits bug:
http://lists.linbit.com/pipermail/drbd-user/2013-January/019480.html

Problem is that I could get v8.3.13 and later to compile on
Debian/Squeeze (I suspect that the 2.6.32 kernel is not supported
anymore, right?).

Any idea/comment will be greatly appreciate. Thanks in anticipation!

Regards,
