I think to make pool-per-user (primary for cephfs; for security, quota, etc), hundreds (or even more) of them. But I remember 2 facts: 1) info in manual about slowdown on many pools; 2) something in later changelog about hashed pool IDs (?). How about now and numbers of pools? And how to avoid serious overheads? -- WBR, Dzianis Kahanovich AKA Denis Kaganovich, http://mahatma.bspu.unibel.by/ _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
