Did you also increase the "pgp_num"? On Saturday, June 28, 2014, Jianing Yang wrote: > Actually, I did increase PG number to 32768 (120 osds) and I also use > "tunable optimal".

Re: [ceph-users] OSD Data not evenly distributed
Actually, I did increase PG number to 32768 (120 osds) and I also use "tunable optimal". But the data still not distribute evenly.

Re: [ceph-users] OSD Data not evenly distributed
Hi, Increasing PG number for pools that hold data might help if you didn't do that already. Check out this thread: http://lists.ceph.com/pipermail/ceph-users-ceph.com/2014-January/027094.html You might find some tips there (although it was pre firefly).

[ceph-users] OSD Data not evenly distributed
Hi, all My cluster has been running for about 4 month now. I have about 108 osds and all are 600G SAS Disk. Their disk usage is between 70% and 85%. It seems that ceph cannot distribute data evenly by default settings. Is there any configuration that helps distribute data more evenly?
