Thanks. That's a reasonable theory. Maybe I'll look in the code and see if I can confirm it. And it means on my cluster, once an hour would probably be sufficient. >I was sure it was updated exactly once per second. Because there's an infamous cluster log message every time the pgmap updates, I know for me it is about 10 times a minute, in a pattern that is neither periodic nor random. Maybe once per second is the maximum frequency and it depends upon how frequently PGs are written to. -- Bryan Henderson San Jose, California _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
