I heard the solution for this was to restart the osd's.  That fixed it for me.

Subject: Slow requests

Hi,

My log is filling up with warnings about a single slow request that has been 
around for a very long time:

osd.1 10.0.0.2:6800/900 162926 : [WRN] 1 slow requests, 1 included below; 
oldest blocked for > 84446.312051 secs

osd.1 10.0.0.2:6800/900 162927 : [WRN] slow request 84446.312051 seconds old, 
received at 2012-12-15 15:27:56.891437:
osd_sub_op(client.4528.0:19602219 0.fe
3807b5fe/rb.0.11b7.4a933baa.00000008629e/head//0 [] v 53'185888 snapset=0=[]:[] 
snapc=0=[]) v7 currently started


How can I identify the cause of this and how can I cancel this request?

I'm running Ceph on Fedora 17 using the latest RPMs available from ceph.com 
(0.52-6).


Thanks in advance,
