移除節點
從叢集移除儲存裝置01
cc1:cluster> remove_node
1: compute01
2: storage01
Enter index: 2
this command is only applicable for compute or storage nodes
make sure its running instances have been properly terminated or migrated
shutdown the target host before proceeding
Enter 'YES' to confirm: YES
cc1:cluster>
從儲存池移除 OSD
1. Run the remove_osd command to remove each failed OSD.
2. Repeat the process until all missing OSDs have been removed.
3. Use status to verify that all offline OSDs are gone.
cc2:storage> remove_osd
Enter osd id to be removed:
1: osd.0 (hdd)
2: osd.1 (hdd)
3: osd.2 (hdd)
4: osd.3 (hdd)
5: osd.4 (hdd)
6: osd.5 (hdd)
7: osd.6 (hdd)
8: osd.7 (hdd)
Enter index: 1
Enter 'YES' to confirm: YES
Remove osd.0 successfully.
