(Linux下的stratis高级存储)

一、stratis存储介绍

1.stratis存储简介

2.stratis的架构图

3.stratis存储的高级特性

4.stratis的专业术语

blockdev:这是一个块设备，例如磁盘或磁盘分区
Pool池:一个池由一个或多个具有固定总大小的块设备组成，其大小等于块设备的总大小。
filesystem文件系统:每个池可以包含一个或多个文件系统，用于存储文件。
文件系统没有固定的总大小，如果数据的大小接近文件系统的虚拟大小，分层就会自动增加卷和文件系统空间大小，只要池的物理空间充够大，就不用担心文件系统空间会爆掉

5.stratis支持的设备

iSCSI
LVM逻辑卷
Device Mapper Multipath设备多路径
硬盘驱动器
LUKS
SSDs
NVMe存储设备
mdraid软件Raid

二、配置stratis精简池

1.系统版本

[root@node2 ~]# cat /etc/os-release 
NAME="Red Hat Enterprise Linux"
VERSION="8.0 (Ootpa)"
ID="rhel"
ID_LIKE="fedora"
VERSION_ID="8.0"
PLATFORM_ID="platform:el8"
PRETTY_NAME="Red Hat Enterprise Linux 8.0 (Ootpa)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:redhat:enterprise_linux:8.0:GA"
HOME_URL="https://www.redhat.com/"
BUG_REPORT_URL="https://bugzilla.redhat.com/"

REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 8"
REDHAT_BUGZILLA_PRODUCT_VERSION=8.0
REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux"
REDHAT_SUPPORT_PRODUCT_VERSION="8.0"

2.安装stratis包

[root@node2 ~]# yum -y install stratis-cli.noarch stratisd

3.开启服务

[root@node2 ~]# systemctl enable --now stratisd

4.创建精简池

[root@node2 ~]# stratis pool create pool01 /dev/sda /dev/sdb

5.查看所有精简池信息

[root@node2 ~]# stratis pool list
Name      Total Physical Size  Total Physical Used
pool01                 40 GiB               72 MiB

6.查看单个精简池详细信息

[root@node2 ~]# stratis  blockdev list pool01
Pool Name  Device Node    Physical Size   State  Tier
pool01     /dev/sda              20 GiB  In-use  Data
pool01     /dev/sdb              20 GiB  In-use  Data

三、配置stratis文件系统

1.创建文件系统

[root@node2 ~]# stratis filesystem create pool01 fs01

2.查看文件系统

[root@node2 ~]# stratis filesystem list 
Pool Name  Name  Used     Created            Device                UUID                              
pool01     fs01  546 MiB  Jun 22 2022 15:14  /stratis/pool01/fs01  3f5b31456c4348e29a11a628ec08dc2a 

四、挂载stratis文件系统

1.查看uuid

[root@node2 ~]# lsblk --output=UUID /stratis/pool01/fs01
UUID
3f5b3145-6c43-48e2-9a11-a628ec08dc2a

2.配置自动挂载

[root@node2 ~]# cat /etc/fstab 

#
# /etc/fstab
# Created by anaconda on Fri Mar 19 22:38:50 2021
#
# Accessible filesystems, by reference, are maintained under /dev/disk/.
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info.
#
# After editing this file, run systemctl daemon-reload to update systemd
# units generated from this file.
#
UUID=87963a70-7bf1-415a-90dc-952c441fb8a9 /                       xfs     defaults        0 0
UUID=67c8633f-d3f0-4901-9677-c5bdf032d810 /boot                   xfs     defaults        0 0
UUID=86cc5bb5-f6fa-45de-9d97-efef926f6549 swap                    swap    defaults        0 0
UUID=3f5b3145-6c43-48e2-9a11-a628ec08dc2a /data/stratis xfs defaults,x-systemd.requires=stratisd.service 0 0 

3.挂载目录

[root@node2 ~]# 
[root@node2 ~]# mount -a

4.查看磁盘

[root@node2 ~]# df -hT |grep stratis
/dev/mapper/stratis-1-2b0561ccf26a47ae96f08e0ff198654c-thin-fs-3f5b31456c4348e29a11a628ec08dc2a xfs       1.0T  7.2G 1017G   1% /data/stratis

五、向精简池添加设备

[root@node2 ~]# stratis pool add-data pool01 /dev/sdd

六、stratis的快照设置

1.创建快照

[root@node2 ~]# stratis filesystem snapshot pool01 fs01 snap01

2.恢复快照

①删除文件系统

[root@node2 ~]# umount /stratis/pool01/fs01
[root@node2 ~]# stratis  filesystem destroy pool01 fs

②还原文件系统

[root@node2 ~]# stratis filesystem snapshot pool01 snap01 fs01
Execution failure caused by:
ALREADY EXISTS: fs01

③查看文件系统

[root@node2 ~]# stratis filesystem list
Pool Name  Name    Used     Created            Device                  UUID                              
pool01     fs01    546 MiB  Jun 22 2022 15:14  /stratis/pool01/fs01    3f5b31456c4348e29a11a628ec08dc2a  
pool01     snap01  546 MiB  Jun 22 2022 15:26  /stratis/pool01/snap01  958fe41bcd3342a79bb95709f97c40c2 

七、startis的基本管理

1.查看文件系统

[root@node2 ~]# stratis filesystem list
Pool Name  Name    Used     Created            Device                  UUID                              
pool01     fs01    546 MiB  Jun 22 2022 15:14  /stratis/pool01/fs01    3f5b31456c4348e29a11a628ec08dc2a  
pool01     snap01  546 MiB  Jun 22 2022 15:26  /stratis/pool01/snap01  958fe41bcd3342a79bb95709f97c40c2 

2.查看精简池

[root@node2 ~]#  stratis  blockdev list pool01
Pool Name  Device Node    Physical Size   State  Tier
pool01     /dev/sda              20 GiB  In-use  Data
pool01     /dev/sdb              20 GiB  In-use  Data

3.删除文件系统

[root@node2 ~]# stratis  filesystem destroy pool01 fs

4.删除精简池

[root@node2 ~]# stratis pool destroy pool01
