第一步:在/root/ceph 目录下执行(第一个节点)
ceph-deploy purge ceph01 ceph02 ceph03 ceph04
ceph-deploy purgedata ceph01 ceph02 ceph03 ceph04
ceph-deploy forgetkeys
rm -rf ceph.*
第二步:在/root 目录下执行(节点1、节点2、节点3、节点4):
result_VG=`vgdisplay | grep "ceph" |awk '{print $3}'`
for vg in ${result_VG}
do
vgremove -f ${vg}
done
第三步:自动化框架清理:
第四步:清理缓存(每个节点执行)
需要提前安装nvme 工具

提取码:s3g6
cfdisk /dev/nvme0n1
cfdisk /dev/nvme1n1
nvme format -s 1 -f /dev/nvme0n1
nvme format -s 1 -f /dev/nvme1n1
查看分区:
lsblk
#对之前的bcache解绑定
对ceph1-4节点/sys/fs/bcache/目录进行unregister操作
#!/bin/bash
for n in {1..4}
do
echo "ceph0$n"
f=$(ssh ceph0$n "ls /sys/fs/bcache/")
for i in $f
do
ssh ceph0$n "echo 1 > /sys/fs/bcache/$i/unregister"
done
done
#对系统下sda…sdh硬盘进行detach,stop操作,dd写操作
for i in {0..7}
do
temp=`expr $i % 8 + 97`
diskID=$(printf \\x`printf %x ${temp}`)
echo 1 >/sys/block/sd${diskID}/bcache/detach
echo 1 >/sys/block/sd${diskID}/bcache/stop
dd if=/dev/zero of=/dev/sd${diskID} count=2048 bs=1M
done
第五步:重启系统(每个节点)
nvme盘清完后,bcache分区会清除不了,重启bcache分区会自动清除
第六步:重启后执行下面命令
wipefs -a /dev/sda
wipefs -a /dev/sdb
wipefs -a /dev/sdc
wipefs -a /dev/sdd
wipefs -a /dev/sde
wipefs -a /dev/sdf
wipefs -a /dev/sdg
wipefs -a /dev/sdh
wipefs -a /dev/nvme0n1
wipefs -a /dev/nvme1n1
再次执行,没有回显表示正常
第七步:清除ceph
sudo rm -rf /var/lib/ceph/osd/*
sudo rm -rf /var/lib/ceph/mon/*
sudo rm -rf /var/lib/ceph/mds/*
sudo rm -rf /var/lib/ceph/bootstrap-mds/*
sudo rm -rf /var/lib/ceph/bootstrap-osd/*
sudo rm -rf /var/lib/ceph/bootstrap-mon/*
sudo rm -rf /var/lib/ceph/tmp/*
sudo rm -rf /etc/ceph/*
sudo rm -rf /var/run/ceph/*
rm -rf /etc/ceph/*
rm -rf /root/ceph/*
rm -rf /var/lib/ceph/*/*
rm -rf /var/log/ceph/*
rm -rf /var/run/ceph/*
userdel -r ceph # 清除ceph用户
