[Ocfs2-users] 答复: ceph osd mounting issue with ocfs2 file system

[gjprabu]

Hi Team,



         We are going to use ceph with ocfs2 in production, here my doubt is 12 clients performance and throughput with 1Gig is enough or need to change network level.



Regards

Prabu

Hi, 



The number of the node should begin with 1 in the  cluster.conf, you can try it. 

I always start with 1. 



You should check the  directory: ls -al /sys/kernel/config/cluster/pool/node ; and all the three node should have same node directory information on three nodes. 



Otherwise, umount all the fs, copy one /etc/ocfs2/cluster.conf to other two node. 

service o2cb offline/unload ;  service o2cb online ;

Remount the disk again and check the nodes info again. 



The cluter.conf file should be same on everyone node.
