解压vdbench
mkdir vdbench
cd vdbench/
unzip ../vdbench50407.zip 
安装jdk8
yum install java-1.8.0-openjdk
故障处理
Module 'restful' has failed dependency: No module named werkzeug.serving
# 目前看，python3应该不对
yum install python3-werkzeug -y
ssh ceph-1 yum install python3-werkzeug -y
ssh ceph-2 yum install python3-werkzeug -y
ssh ceph-3 yum install python3-werkzeug -yyum install python2-werkzeug -y
ssh ceph-1 yum install python2-werkzeug -y
ssh ceph-2 yum install python2-werkzeug -y
ssh ceph-3 yum install python2-werkzeug -y重启ceph-mon(ssh 执行方式发现不能批量输入到终端执行，需要一条一条跑)
systemctl restart ceph-mon@ceph-0.servicessh ceph-1 systemctl restart ceph-mon@ceph-1.service
ssh ceph-2 systemctl restart ceph-mon@ceph-2.service
ssh ceph-3 systemctl restart ceph-mon@ceph-3.service结果依旧，reboot所有主机
重启后故障，只有osd进程在，其他服务均未自启动
配置服务自启动
所有服务文件参考如下
[root@ceph-0 ~]# systemctl enable --now ceph-mon@ceph-0.service
[root@ceph-0 ~]# systemctl enable --now ceph-mgr@ceph-0.service[root@ceph-1 ~]# systemctl enable --now ceph-mon@ceph-1.service
[root@ceph-1 ~]# systemctl enable --now ceph-mgr@ceph-1.service[root@ceph-2 ~]# systemctl enable --now ceph-mon@ceph-2.service
[root@ceph-2 ~]# systemctl enable --now ceph-mgr@ceph-2.service [root@ceph-3 ~]# systemctl enable --now ceph-mon@ceph-3.service
[root@ceph-3 ~]# systemctl enable --now ceph-mgr@ceph-3.service 4台服务器禁用防火墙
systemctl disable firewalld --now手动恢复服务，关闭防火墙后ceph -s
1 pool(s) have non-power-of-two pg_num
clock skew detected（需要一段时间后才会恢复）
ntpdate ceph-0 重启ntpd效果依旧
原来的语句有错，应该设置为2的次方
ceph osd pool create vdbench 250 250查看pool列表
修改 pg pgs
ceph osd pool set vdbench pg_num 256
ceph osd pool set vdbench pgp_num 256
搞定了以上两个问题
too many PGs per OSD (256 > max 250)
一天后
ceph osd pool set vdbench pg_num 128
ceph osd pool set vdbench pgp_num 128
由于防火墙中途其他事项开启了，导致配置未同步。后续重启ceph-mon后，该问题已消失！
发现块设备消失了
删除image pool（失败）
[root@ceph-0 ~]# rbd ls vdbench
image1
[root@ceph-0 ~]# rbd rm vdbench/image1
Removing image: 100% complete...done.
[root@ceph-0 ~]# ceph osd pool rm vdbench vdbench --yes-i-really-really-mean-it
Error EPERM: pool deletion is disabled; you must first set the mon_allow_pool_delete config option to true before you can destroy a pool
删除pool 需要提前设置配置文件
mon_allow_pool_delete
修改/etc/ceph/ceph.conf，[global]下添加一句
mon_allow_pool_delete = true
推送配置到其他节点
cd /etc/ceph/
ceph-deploy --overwrite-conf config push ceph-1 ceph-2 ceph-3
重启4个节点的ceph-mon
systemctl restart ceph-mon@ceph-0.servicessh ceph-1 systemctl restart ceph-mon@ceph-1.service
ssh ceph-2 systemctl restart ceph-mon@ceph-2.service
ssh ceph-3 systemctl restart ceph-mon@ceph-3.serviceceph -s 已恢复
继续删除pool vdbench
[root@ceph-0 ceph]# ceph osd pool rm vdbench vdbench --yes-i-really-really-mean-it
pool 'vdbench' removed
注意，删除指令需要重复写一次pool名字，后面加上参数--yes-i-really-really-mean-it
重新创建pool，指定pg pgs 128
[root@ceph-0 ceph]# ceph osd pool create vdbench 128 128
pool 'vdbench' created
[root@ceph-0 ceph]# ceph osd pool application enable vdbench rbd
enabled application 'rbd' on pool 'vdbench'
[root@ceph-0 ceph]# rbd create image1 --size 20G --pool vdbench --image-format 2 --image-feature layering
[root@ceph-0 ceph]# rbd map vdbench/image1
/dev/rbd0
[root@ceph-0 ceph]# fdisk -l /dev/rbd0
Disk /dev/rbd0: 20 GiB, 21474836480 bytes, 41943040 sectors

在ceph-0测试vdbench（报错）
配置文件/root/vdbench/single-rawdisk.conf
sd=sd1,lun=/dev/rbd0 ,openflag=o_direct
wd=wd1,sd=sd1,seekpct=0,rdpct=0,xfersize=1M
rd=rd1,wd=wd1,iorate=max,warmup=60,elapsed=600,interval=2执行测试
./vdbench -f single-rawdisk.conf
故障：File /root/vdbench/linux/aarch64.so does not exist

解压
cd vdbench-src/
unzip ../vdbench50407.src.zip 安装jdk-devel
yum install -y java-1.8.0-openjdk-devel修改make.linux
差异如下
