Hey, Those out there who are running production clusters: have you upgraded already to Jewel? I usually wait until .2 is out (which it is now for Jewel) but just looking for largish deployment experiences in the field before I pull the trigger over the weekend. It’s a largish upgrade going from ~460TB to 1.2PB and at this point I’m just overly cautious.
One of the main reasons I want to upgrade to is to get the new IO queuing code so the recovery ops won’t hit the VM workloads (that much). (Yes, we have it configured properly, but even one backfill is visible in our client IO…) Other than that I’m happy with hammer. Cheers, Zoltan _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
