Hello I have a 5-server cluster and I am wondering if it's possible to create pool that uses k=5 m=2 erasure code. In my experiments, I ended up with pools whose pgs are stuck in creating+incomplete state even when I created the erasure code profile with --crush-failure-domain=osd.
Assuming that what I want to do is possible, will CRUSH distribute chunks evenly among servers, so that if I need to bring one server down (e.g. reboot), clients' ability to write or read any object would not be disrupted? (I guess something would need to ensure that no server holds more than two chunks of an object) Thanks, Vlad _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
