Hi,

If you want to split your data to 10 peaces (stripes), and hold 4 parity peaces in extra (so your cluster can handle the loss of any 4 osds), then you need a minimum of 14 osds to hold your data.

Hi,

I would like to set up an erasure code profile with k=10 amd m=4 settings.

Is there any minimum requirement of OSD nodes and OSDs to achieve this setting ?

Can I create a pool with 8 OSD servers, with one disk each in it ?
