Thanks for the tip on power of 2 shard numbers. I want to say I've read that, too. We have a small window where I can re-shard the index before we sync the other 2 zones. Will check on OSD logs, as well. As to the SSDs – yes, I've confirmed that the bucket index is placed only on those two SSDs via a 2 x replicated rule. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
