Hi , Could you attach the detail reproducing steps? Are you using the following steps to get crush.new.txt and base on it to modify new crush ? $ ceph osd getcrushmap -o crush.new $ crushtool -d crush.new -o crush.new.txt Maybe , you could refer to the following commands to create crush.new file,for instance: $ crushtool --num_osds 8 -o crush.new --build host straw 8 rack straw 8 root straw 0 $ crushtool -d crush.new -o crush.new.txt I had filed two bug at : http://tracker.newdream.net/issues/1016 http://tracker.newdream.net/issues/1017 Jeff ,Wu On Sun, 2011-05-29 at 21:21 +0800, Fyodor Ustinov wrote: > Hi! > > Now, I made an attempt to create my own CRUSH. > > After I applied it to existing cluster everything stopped (rebalance not > start, unable to mount cluster) > > "Ok", I said and created new cluster with this crush. > > Cluster turned out as the real thing.
