Hi,
I'm using Jewel / 10.2.3-0ubuntu0.16.04.2 . We want to keep track of our
S3 users' quota and usage. Even with a relatively small number of users
(23) it's taking ~23 seconds.
What we do is (in outline):

First of all, don't do a ceph upgrade while your cluster is in warning or
error state. A process upgrade must be done from an clean cluster.
Don't stay with a replicate at 2. Majority of problems come from that

Hello,
After a major network outage our ceph cluster ended up with an inactive PG:
# ceph health detail
HEALTH_WARN 1 pgs incomplete; 1 pgs stuck inactive; 1 pgs stuck unclean; 1
requests are blocked > 32 sec; 1 osds have slow requests
pg 3.367 is stuck inactive for 912263.766607, current state
Thanks for the confirmations of what is possible.
We plan on creating a new file system, rsync and delete the old one.

Hi,
I am trying to use ceph with RDMA. I have a few questions.
1. Is there a prebuilt package that has rdma support or the only way to try
ceph+rdma is to checkout from github and compile from scratch?
2. Looks like there are two ways of using rdma - xio and async+rdma. Which
is the recommended
Thanks everyone for the input. We are online in our test environment and are

AFAIK depending on how many you have, you are likely to end up with 'too
many pgs per OSD' warning for your main pool if you do this, because the
number of PGs in a pool cannot be reduced and there will be less OSDs to
put them on.

re: python library
you can do some mon calls using this:
##--
from ceph_argparse import json_command as json_command
rados_inst = rados.Rados()
cluster_handle = rados_inst.connect()
cmd = {'prefix': 'pg dump', 'dumpcontents': ['summary', ], 'format': 'json'}
retcode, jsonret, errstr
There was definitely missing the "list watchers" command.

Thanks for your reply.
As the log shows, in our test, a READ that come after a WRITE did finished
before that WRITE. And I read the source code, it seems that, for writes, in
ReplicatedPG::do_op method, the thread in OSD_op_tp calls
ReplicatedPG::get_rw_lock method which tries to get RWState::R

Hi,
We compiled Hammer .10 to use jemalloc and now the cluster performance improved
a lot, but POSIX AIO operations are still quite slower than libaio.
Now with a single thread read operations are about 1000 per second and write
operations about 5000 per second.
Using same FIO configuration,

you can improve latency on client with disable debug.
