Hi all,
Soon, we should have a 3 datacenters (dc) ceph cluster with 4 hosts in each dc.
Each host will have 12 OSD.
We can accept the loss of one datacenter and one host on the remaining 2
datacenters.
In order to use erasure coded pool :
1. Is the solution for a strategy k = 7, m = 5 is acceptable ?
2. Is this is the only one that guarantees us our premise ?
3. And more generally, is there a formula (based on the number of dc, host
and OSD) that allows us to calculate the profile ?
Thanks.
Stephane.
