  • 清理rookceph

    官方步骤文档:https://rook.io/docs/rook/v1.8/ceph-teardown.html

    请注意需要清理的以下资源:

    • rook-ceph namespace: The Rook operator and cluster created by operator.yaml and cluster.yaml (the cluster CRD)
    • /var/lib/rook: Path on each host in the cluster where configuration is cached by the ceph mons and osds

    Delete the Block and File artifacts

    # 如下这些文件是官方文档中演示使用到的,若是没有操作过则可以跳过这一步
    kubectl delete -f ../wordpress.yaml
    kubectl delete -f ../mysql.yaml
    kubectl delete -n rook-ceph cephblockpool replicapool
    kubectl delete storageclass rook-ceph-block
    kubectl delete -f csi/cephfs/kube-registry.yaml
    kubectl delete storageclass csi-cephfs
    

    Delete the CephCluster CRD

    kubectl -n rook-ceph patch cephcluster rook-ceph --type merge -p '{"spec":{"cleanupPolicy":{"confirmation":"yes-really-destroy-data"}}}'
    
    kubectl -n rook-ceph delete cephcluster rook-ceph
    kubectl -n rook-ceph get cephcluster
    
    • 删除所有节点上的目录/var/lib/rook(或dataDirHostPath指定的路径)
    • 擦除此群集中运行OSD的所有节点上驱动器上的数据

    Delete the Operator and related Resources

    kubectl delete -f operator.yaml
    kubectl delete -f common.yaml
    kubectl delete -f crds.yaml
    

    Delete the data on hosts

    连接到每台计算机并删除/var/lib/rook或dataDirHostPath指定的路径。

    擦除磁盘数据

    #!/usr/bin/env bash
    DISK="/dev/sdb" # 根据实际情况修改(裸磁盘)
    
    # Zap the disk to a fresh, usable state (zap-all is important, b/c MBR has to be clean)
    
    # You will have to run this step for all disks.
    sgdisk --zap-all $DISK
    
    # Clean hdds with dd
    dd if=/dev/zero of="$DISK" bs=1M count=100 oflag=direct,dsync
    
    # Clean disks such as ssd with blkdiscard instead of dd
    blkdiscard $DISK
    
    # These steps only have to be run once on each node
    # If rook sets up osds using ceph-volume, teardown leaves some devices mapped that lock the disks.
    ls /dev/mapper/ceph-* | xargs -I% -- dmsetup remove %
    
    # ceph-volume setup can leave ceph-<UUID> directories in /dev and /dev/mapper (unnecessary clutter)
    rm -rf /dev/ceph-*
    rm -rf /dev/mapper/ceph--*
    
    # Inform the OS of partition table changes
    partprobe $DISK
