Hi,
Recently I`ve reduced my test suite from 6 to 4 osds at ~60% usage on
six-node,
and I have removed a bunch of rbd objects during recovery to avoid
overfill.
Right now I`m constantly receiving a warn about nearfull state on
non-existing osd:
health HEALTH_WARN 1 near full osd(s)

yours is a underlying fs - I`m tired of btrfs unpredictable load

This is most likely due to a recently-fixed problem.
The fix is found in this commit, although there were
other changes that led up to it:

Hi,
For Stefan:
Increasing socket memory gave me about some percents on fio tests
inside VM(I have measured
'max-iops-until-ceph-throws-message-about-delayed-write' parameter).
What is more important, osd process, if possible, should be pinned to
dedicated core or two, and all other processes
Hi,
I`ve run in almost same problem about two months ago, and there is a
couple of corner cases: near-default tcp parameters, small journal
size, disks that are not backed by controller with NVRAM cache and
high load on osd` cpu caused by side processes. Finally, I have able
to achieve 115Mb/s

Hello everyone,
I have just tried ceph collectd fork on wheezy and noticed that all
logs for ceph plugin produce nothing but zeroes(see below) for all
types of nodes. Python cephtool works just fine. Collectd run as root
and there is no obvious errors like socket permissions and no tips

I have tested all of them about a week ago, all works fine. Also it
will be very nice if rbd can list an actual allocated size of every
image or snapshot in future.

Hi Wido,
I am looking for doing the snapshots via
: Disk 'rbd/vm1:rbd_cache_enabled=1'
does not support snapshotting
maybe the rbd_cache option is the problem?

feel it's up to the sysadmin to mount / symlink the correct storage devices
on the correct paths - ceph should not be concerned that some volumes might
need to sit together.

Are you sure about that?

Suggested hack works, seems that libvirt devs does not remove block

it.
