I'm seeing the same sort of issue.
Any suggestions on how to get Ceph to not start the ceph-osd processes
on host boot? It does not seem to be as simple as just disabling the
service

I'm passing settings to the admin socket ie:

@John,
Can you clarify which values would suggest that my metadata pool is too
slow? I have added a link that includes values for the "op_active"
& "handle_client_request"gathered in a crude fashion but should
hopefully give enough data to paint a picture of what is happening.

Hi,
I was using RADOS bench to test on a single node ceph cluster with a dedicated
SSD as storage for my OSD.
I created a pool to do the same and filled up my ssd until maximum capacity
using RADOS bench with my object size as 4k. On removing the pool, I noticed
that it seems to take a really lo

hi, wido,
we would love to provide such mirror in china(cn.ceph.com). we are using
ceph heavily in our system while we also want to give
feedback to the community.
I am now consulting our IDC operators how we can do this.
I will see what I can do for ceph community very soon.
cheers,

Now, with enough memory you can easily have 100 PGs per OSD, but keep in
mind that the PG count is cluster-wide and

We have 48 OSDs (on 12 boxes, 4T per OSD) and 4 pools:
- 3 replicated pools (3x)
- 1 RS pool (5+2, size 7)
The docs say:
http://ceph.com/docs/master/rados/operations/placement-groups/
"Between 10 and 50 OSDs set pg_num to 4096"
Which is what we did when creating those pools. This yields 16384 PG
