Hi,
Another consideration probably is the size of the packet sent over the network.
Samuel Just chose this default value but I never asked about the rationale.
Regarding the stripe width, it actually is stored per pool although it does not
look that way. If you want to configure a pool with a
Hi Loic,
At present, I test different stripe-width(4k,16k,32k,256k,512k, 1024k) with
k=3/m=2. I used cosbench+librados to test the performance with
10MB-write(object size).

It's not very intuitive or easy to look at right now (there are plans
from the recent developer summit to improve things), but the central
log should have output about exactly what objects are busted. You'll

CRUSH is a probabilistic algorithm. By having all those non-existent
OSDs in the map, you made it so that 10/12 attempts at mapping would
fail and need to be retried. CRUSH handles a lot of retries, but not
enough for that to work out well.

We don't test explicitly for this, but I'm surprised to hear about a

you generate some? (With the tcmalloc heap dumps.)

What was the exact sequence of events — were you rebalancing when you
did the upgrade? Did the marked out OSDs get upgraded?
Did you restart all the monitors prior to changing the tunables? (Are

Do you have a ceph.conf file that the "ceph" tool can access in a
known location? Try specifying it manually with the "-c ceph.conf"
argument. You can also add "--debug-ms 1, --debug-monc 10" and see if
it outputs more useful error logs.

Hi,
If you add an OSD to an existing cluster, ceph will move some existing
data around so the new OSD gets its respective share of usage right away.
Now I noticed that during this moving around, ceph reports the relevant
PG's as degraded. I can more or less understand the logic here: if a

Just as a side note, you can now try the civetweb backend of rgw so

You'd have to see why the other daemons are not running, try:

And start the missing OSDs.
But I have ceph osd rm them. so?
