hi, all When I run command 'ceph-deploy disk list nodename', there are some warning messages indicate partition table error, but the ceph cluster is working normally. What is the problem, should I run sgdisk command to repair the partition table? Below is the warning messages: ceph@controller-11:~$ ceph-deploy disk list c13 [ceph_deploy.conf][DEBUG ] found configuration file at: /home/ceph/.cephdeploy.conf [ceph_deploy.cli][INFO ] Invoked (1.5.5): /usr/bin/ceph-deploy disk list c13 [c13][DEBUG ] connected to host: c13 [c13][DEBUG ] detect platform information from remote host [c13][DEBUG ] detect machine type [ceph_deploy.osd][INFO ] Distro info: Ubuntu 13.04 raring [ceph_deploy.osd][DEBUG ] Listing disks on c13...
