Purge a Host

When you remove Ceph daemons and uninstall Ceph, there may still be extraneous data from the cluster on your server. The purge and purgedata commands provide a convenient means of cleaning up a host.

Purge Data

To remove all data from /var/lib/ceph (but leave Ceph packages intact), execute the purgedata command.

ceph-deploy purgedata {hostname} [{hostname} …]


To remove all data from /var/lib/ceph and uninstall Ceph packages, execute the purge command.

ceph-deploy purge {hostname} [{hostname} …]
