CEPH-9311 - RADOS: Pyramid erasure codes (Local Repai rable erasure codes):
Bring down 2 osds (in case of k=4) from 2 localities so that recovery happens from local repair code
1. Create a LRC profile and then create a ec pool
#ceph osd erasure-code-profile set $profile \
plugin=lrc \
k=4 m=2 l=3 \
ruleset-failure-domain=osd
# ceph osd pool create $poolname 1 1 erasure $profile
2. start writing objects to the pool
# rados -p poolname bench 1000 write --no-cleanup
3. Bring down 2 osds from 2 different localities which contains data chunk:(for this we need to figure out
mapping) for ex: with k=4, m=2, l=3 mapping looks like
chunk nr 01234567
step 1 _cDD_cDD (Here DD are data chunks )
step 2 cDDD____
step 3 ____cDDD
from "step 1" in the above mapping we can see that
data chunk is divided into 2 localities which is
anlogous to 2 data center. so in our case for ex
we have to bring down (3,7) OR (2,7) OR (2,6) OR (3,6) .
