测试目标

使用rbd映射挂载块存储并测试性能

使用rbd-nbd映射挂载条带块存储并测试性能使用s3brower测试对象存储读写使用s3fs挂载挂载对象存储使用对象存储写使用块存储读

一，使用rbd映射挂载块存储并测试性能

1、创建image

[root@idcv-ceph0 cluster]# ceph osd pool create test_pool 100

pool 'test_pool' created

[root@idcv-ceph0 cluster]# rados lspools

rbd

.rgw.root

default.rgw.control

default.rgw.data.root

default.rgw.gc

default.rgw.log

default.rgw.users.uid

default.rgw.users.keys

default.rgw.buckets.index

default.rgw.buckets.data

test_pool

[root@idcv-ceph0 cluster]# rbd list

[root@idcv-ceph0 cluster]# rbd create test_pool/testimage1 --size 40960

[root@idcv-ceph0 cluster]# rbd create test_pool/testimage2 --size 40960

[root@idcv-ceph0 cluster]# rbd create test_pool/testimage3 --size 40960

[root@idcv-ceph0 cluster]# rbd create test_pool/testimage4 --size 40960

[root@idcv-ceph0 cluster]# rbd list

[root@idcv-ceph0 cluster]# rbd list test_pool

testimage1

testimage2

testimage3

testimage4

2、映射image

[root@idcv-ceph0 cluster]# rbd map test_pool/testimage1

rbd: sysfs write failed

RBD image feature set mismatch. You can disable features unsupported by the kernel with "rbd feature disable".

In some cases useful info is found in syslog - try "dmesg | tail" or so.

rbd: map failed: (6) No such device or address

[root@idcv-ceph0 cluster]# dmesg |tail

[113320.926463] rbd: loaded (major 252)

[113381.411625] rbd: image testimage1: image uses unsupported features: 0x38

报错处理方法：disable新特性

[root@idcv-ceph0 cluster]# rbd info test_pool/testimage1

rbd image 'testimage1':

size 40960 MB in 10240 objects

order 22 (4096 kB objects)

block_name_prefix: rbd_data.10802ae8944a

format: 2

features: layering, exclusive-lock, object-map, fast-diff, deep-flatten

flags:

[root@idcv-ceph0 cluster]# rbd feature disable test_pool/testimage1

rbd: at least one feature name must be specified

[root@idcv-ceph0 cluster]# rbd feature disable test_pool/testimage1 fast-diff

[root@idcv-ceph0 cluster]# rbd feature disable test_pool/testimage1 object-map

[root@idcv-ceph0 cluster]# rbd feature disable test_pool/testimage1 exclusive-lock

[root@idcv-ceph0 cluster]# rbd feature disable test_pool/testimage1 deep-flatten

[root@idcv-ceph0 cluster]# rbd info test_pool/testimage1

rbd image 'testimage1':

size 40960 MB in 10240 objects

order 22 (4096 kB objects)

block_name_prefix: rbd_data.10802ae8944a

format: 2

features: layering

flags:

[root@idcv-ceph0 cluster]# rbd map test_pool/testimage1

/dev/rbd0

同理操作testimage2\3\4，最终如下

[root@idcv-ceph0 cluster]# rbd showmapped

id pool image snap device

0 test_pool testimage1 - /dev/rbd0

1 test_pool testimage2 - /dev/rbd1

2 test_pool testimage3 - /dev/rbd2

3 test_pool testimage4 - /dev/rbd3

备注收缩image大小

[root@idcv-ceph0 ceph-disk0]# rbd resize -p test_pool --image testimage1 -s 10240 --allow-shrink

Resizing image: 100% complete...done.

[root@idcv-ceph0 ceph-disk0]# rbd resize -p test_pool --image testimage2 -s 10240 --allow-shrink

Resizing image: 100% complete...done.

[root@idcv-ceph0 ceph-disk0]# rbd resize -p test_pool --image testimage3 -s 10240 --allow-shrink

Resizing image: 100% complete...done.

[root@idcv-ceph0 ceph-disk0]# rbd resize -p test_pool --image testimage4 -s 10240 --allow-shrink

Resizing image: 100% complete...done.

3、格式化挂载

[root@idcv-ceph0 ceph-disk0]# mkfs.xfs /dev/rbd0

[root@idcv-ceph0 ceph-disk0]# mkfs.xfs -f /dev/rbd0

4、DD测试

[root@idcv-ceph0 ceph-disk0]# dd if=/dev/zero of=/mnt/ceph-disk0/file0 count=1000 bs=4M conv=fsync

1000+0 records in

1000+0 records out

4194304000 bytes (4.2 GB) copied, 39.1407 s, 107 MB/s

二、使用rbd-nbd映射挂载条带块存储并测试性能

1、创建image

根据官网文档条带化测试需要带参数--stripe-unit及--stripe-count计划测试object-size为4M、4K且count为1时，object-szie为32M且count为8、16时块存储性能

[root@idcv-ceph0 ceph-disk0]# rbd create test_pool/testimage5 --size 10240 --stripe-unit 2097152 --stripe-count 16

[root@idcv-ceph0 ceph-disk0]# rbd info test_pool/testimage5

rbd image 'testimage5':

size 10240 MB in 2560 objects

order 22 (4096 kB objects)

block_name_prefix: rbd_data.10c52ae8944a

format: 2

features: layering, striping, exclusive-lock, object-map, fast-diff, deep-flatten

flags:

stripe unit: 2048 kB

stripe count: 16

[root@idcv-ceph0 ceph-disk0]# rbd create test_pool/testimage6 --size 10240 --stripe-unit 4096 --stripe-count 4

[root@idcv-ceph0 ceph-disk0]# rbd info test_pool/testimage6

rbd image 'testimage6':

stripe count: 4

[root@idcv-ceph0 ceph-disk0]# rbd create test_pool/testimage7 --size 10240 --object-size 32M --stripe-unit 4194304 --stripe-count 4

[root@idcv-ceph0 ceph-disk0]# rbd info test_pool/testimage7

rbd image 'testimage7':

order 25 (32768 kB objects)

block_name_prefix: rbd_data.107e238e1f29

format: 2

features: layering, striping, exclusive-lock, object-map, fast-diff, deep-flatten

flags:

stripe count: 4

[root@idcv-ceph0 ceph-disk0]# rbd create test_pool/testimage8 --size 10240 --object-size 32M --stripe-unit 2097152 --stripe-count 16

[root@idcv-ceph0 ceph-disk0]# rbd info test_pool/testimage8

rbd image 'testimage8':

size 10240 MB in 320 objects

order 25 (32768 kB objects)

block_name_prefix: rbd_data.109d2ae8944a

format: 2

features: layering, striping, exclusive-lock, object-map, fast-diff, deep-flatten

flags:

stripe unit: 2048 kB

stripe count: 16

[root@idcv-ceph0 ceph-disk0]# rbd create test_pool/testimage11 --size 10240 --object-size 4M

[root@idcv-ceph0 ceph-disk0]# rbd create test_pool/testimage12 --size 10240 --object-size 4K

[root@idcv-ceph0 ceph-disk0]# rbd info test_pool/testimage11

rbd image 'testimage11':

size 10240 MB in 2560 objects

order 22 (4096 kB objects)

block_name_prefix: rbd_data.10ac238e1f29

format: 2

features: layering, exclusive-lock, object-map, fast-diff, deep-flatten

flags:

[root@idcv-ceph0 ceph-disk0]# rbd info test_pool/testimage12

rbd image 'testimage12':

size 10240 MB in 2621440 objects

order 12 (4096 bytes objects)

block_name_prefix: rbd_data.10962ae8944a

features: layering, exclusive-lock, object-map, fast-diff, deep-flatten

flags:

2、映射image

[root@idcv-ceph2 mnt]# rbd map test_pool/testimage8

rbd: sysfs write failed

In some cases useful info is found in syslog - try "dmesg | tail" or so.

rbd: map failed: (22) Invalid argument

[root@idcv-ceph2 mnt]# dmesg |tail

3、排错发现rbd不支持条带特性需要需要使用rbd-nbd

rbd-nbd支持所有的新特性，后续map时也不需要disable新特性，但是linux内核默认没有nbd模块，需要编译内核安装，可以参考下面链接https://blog.csdn.net/miaodichiyou/article/details/76050361

[root@idcv-ceph2 ~]# wget

[root@idcv-ceph2 ~]# rpm -ivh kernel-3.10.0-862.2.3.el7.src.rpm

[root@idcv-ceph2 ~]# cd /root/rpmbuild/

[root@idcv-ceph0 3.10.0-862.6.3.el7.x86_64]# lsmod |grep nbd

nbd 17554 5

4、使用rbd-nbd映射image

[root@idcv-ceph0 ~]# rbd-nbd map test_pool/testimage17

/dev/nbd0

[root@idcv-ceph0 ~]# rbd info test_pool/testimage17

rbd image 'testimage17':

7、dd测试结果汇总

8、使用fio随机写测试

先安装fio

yum install libaio-devel

wget

tar zxf fio-2.1.10.tar.gz

cd fio-2.1.10/

make

make install

32M-8

9、fio测试结果汇总

三、使用s3brower测试对象存储读写

1、创建对象存储账号密码

[root@idcv-ceph0 cluster]# radosgw-admin user create --uid=test --display-name="test" --access-key=123456 --secret=123456

[root@idcv-ceph0 cluster]# radosgw-admin user info --uid=test

{

"user_id": "test",

"display_name": "test",

"email": "",

"suspended": 0,

"max_buckets": 1000,

"auid": 0,

"subusers": [],

"keys": [

{

"user": "test",

"access_key": "123456",

"secret_key": "123456"

}

],

"swift_keys": [],

"caps": [],

"op_mask": "read, write, delete",

"default_placement": "",

"placement_tags": [],

"bucket_quota": {

"enabled": false,

"max_size_kb": -1,

"max_objects": -1

},

"user_quota": {

"enabled": false,

"max_size_kb": -1,

"max_objects": -1

},

"temp_url_keys": []

}

2、安装配置s3brower

3、创建bucket上传下载测试

四、使用s3fs挂载挂载对象存储读写

测试对象存储方式写入文件，从rbd方式读目录

1、安装部署

安装

查看READMEOn CentOS 7:

sudo yum install automake fuse fuse-devel gcc-c++ git libcurl-devel libxml2-devel make openssl-devel

Then compile from master via the following commands:

git clone https://github.com/s3fs-fuse/s3fs-fuse.gitcd s3fs-fuse./autogen.sh./configuremakesudo make install

[root@idcv-ceph0 ~]# wget

[root@idcv-ceph0 ~]# ls

[root@idcv-ceph0 ~]# tar zxvf v1.83.tar.gz

[root@idcv-ceph0 s3fs-fuse-1.83]# cd s3fs-fuse-1.83/

[root@idcv-ceph0 s3fs-fuse-1.83]# ls

[root@idcv-ceph0 s3fs-fuse-1.83]# vi README.md

[root@idcv-ceph0 s3fs-fuse-1.83]# yum install automake fuse fuse-devel gcc-c++ git libcurl-devel libxml2-devel make openssl-devel

[root@idcv-ceph0 s3fs-fuse-1.83]# ./autogen.sh
