Hi,
I've just started working with Ceph for a couple of weeks. At the
moment, I'm trying to setup a small cluster with 1 monitor, 1 MDS and
6 OSDs. However, I cannot mount ceph to the system no matter which
node I'm executing the mounting command on.
My nodes run Ubuntu 11.10 with kernal

3.2.18 works fine too.
Honestly I don't know if tmpfs journal with dio = false would lead to
that kind of behavior. Anything interesting in the logs if you turn
debugging up?
just stuff like this. But
I got lots of NULL pointer dereference Oops when compiling kernel on ceph.
The bug is because the kernel page migration routine replaces some pages

Hi,
Newer kernel rbd driver throws a quite strange messages on map|unmap,
comparing to 3.2 branch:
rbd map 'path' # device appears as /dev/rbd1 instead of rbd0, then
rbd unmap /dev/rbd1 # causes following trace, w/ vanilla 3.4.0 from kernel.org:

other FS like btrfs.
I used rados -p data bench 100 write -t 16 for all tests and a freshly
created FS. mount options were always: noatime,nodiratime,nobarrier.
3.0.30 with XFS
speed is always between 120 and 160MB/s

That looks like a bug that isn't familiar to Josh or I. Can you create a report
in the tracker and provide as much debug info as you can come up with? :)

I'm looking at the description in this API:
http://ceph.com/docs/master/api/librados/#rados_objects_list_next
For the parameters entry and key, the doc said (caller must free).
I looked up in the code, and found this statement in the doc
a bit misleading.
Is the doc outdated, or did I miss
