Hi, unstable branch crushtool is failing for me like this: # crushtool --num_osds 32 -o test.crushmap --build shelf uniform 8 host uniform 1 root straw 0 failed to open log file '/var/log/ceph/': error 21: Is a directory This error seems to happen at crushtool.cc:925: 925 dout(0) << "layer " << type 926 << " " << l.name 927 << " bucket type " << l.buckettype 928 << " " << l.size 929 << dendl; AFAICS commit 986c2af4aeb switched dout to use DoutStreambuf, and by default (commit 952111451c3) everything now logs to a file. What's the right way to get crushtool to log to stdout or stderr? Or, how to I get crushtool to use a log file of my choice?
