Try using more OSDs.
I was encountering this scenario when my osds were equal to k+m
The errors went away when I used k+m+2
So in your case try with 8 or 10 osds.

Subject: Erasure code Plugins Date: Fri, 19 Feb 2016 12:13:36 +0530 From: Daleep Singh Bais <daleepbais@xxxxxxxxx> To: ceph-users <ceph-users@xxxxxxxx>
Hi All,
I am experimenting with erasure profiles and would like to understand more about them. I created an LRC profile based on http://docs.ceph.com/docs/master/rados/operations/erasure-code-lrc/
The LRC profile created by me is
ceph osd erasure-code-profile get lrctest1
k=2
l=2
m=2
plugin=lrc
ruleset-failure-domain=host
ruleset-locality=host
ruleset-root=default
However, when I create a pool based on this profile, I see a health warning in ceph -w ( 128 pgs stuck inactive and 128 pgs stuck unclean). This is the first pool in cluster.
As i understand, m is parity bit and l will create additional parity bit for data bit k. Please correct me if I am wrong.
Below is output of ceph -w
health HEALTH_WARN
128 pgs stuck inactive
128 pgs stuck unclean
monmap e7: 1 mons at {node1=192.168.1.111:6789/0}

osdmap e928: 6 osds: 6 up, 6 in

pgmap v54114: 128 pgs, 1 pools, 0 bytes data, 0 objects
10182 MB used, 5567 GB / 5589 GB avail

Any help or guidance in this regard is highly appreciated.
Thanks,
