Just to add, this doesn't happen in just one pool.
When I change "data" pool replicate size from 2 to 3, a few PGs (3) got
stuck too.
pg 0.7c is active+clean+degraded, acting [8,2]
pg 0.48 is active+clean+degraded, acting [4,8]
pg 0.1f is active+clean+degraded, acting [5,7]

Hi Sage,
Thanks, I noticed after re-reading the documentation.
I realized that osd.8 was not in host3. After adding osd.8 to host3, the
PGs are now in "active+remapped"

Sorry, to set things in context, I had some other problems last weekend.
Setting it to optimal tunables helped (although I am on the older kernel).
Since it worked, I was inclined to believed that the tunables do work on
the older kernel.
That being said, I will upgrade the kernel to see if this i

Hi Sage,
It is on optimal tunables already. However, I'm on kernel
2.6.32-358.6.2.el6.x86_64. Will the tunables take effect or do I have to
upgrade to something newer?

Hi all,
I'm running ceph on CentOS6 on 3 hosts, with 3 OSD each (total 9 OSD).
When I increased one of my pool rep size from 2 to 3, just 6 PGs will get
stuck in active+clean+degraded mode, but it doesn't create new replicas.
One of the problematic PG has the following (snipped for brevity)
