Hi, I want to try out clustered MDS on v0.23. I followed the Wiki at <http://ceph.newdream.net/wiki/MDS_cluster_expansion> and tried to set max_mds to 2, but Ceph doesn't recognize the command. ceph@cepha3:~$ ceph mds set max_mds 2 2010-11-14 00:44:03.008148 mon <- [mds,set,max_mds,2] 2010-11-14 00:44:03.009006 mon0 -> 'unrecognized command' (-22) Can anybody tell me what the right command is? I'm using Ceph v0.32 on Ubuntu 10.10 Server (Kernel 2.6.35).
