Additional info: Trying this with a bog-standard replicated pool (ceph osd pool create reppool 2048 2048) succeeds perfectly. So, I assume the issue is the write-amplification from the ec pool implementation? My current settings are k=10, m=2 Reading in the list, there are additional suggestions about setting k to powers-of-two (which aren't well documented in the official docs...). _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
