ASM

首先讲ASM之前，我们先了解一下RAID0和RAID1的故事吧：
RAID0：最少由两块磁盘组成，以两个100G的磁盘为例，组成200G的磁盘阵列，那用户写入的数据就会往200G的磁盘内进行写入，但是如果一个磁盘损坏，会导致整个RAID0磁盘阵列内的磁盘都不可使用，安全性差，但是读写效率高，硬盘使用率高。
RAID1：最少由两块磁盘组成，以两个100G的磁盘为例，组成100g的磁盘阵列，用户写入的数据只会写入100G的空间内，意思是用户写入的数据会同时写入两个磁盘内，两个磁盘的数据是完全一模一样的，磁盘之间也是数据互通，可以形成一个很好的备份，如果一个磁盘损坏了，第二个磁盘可以接着使用，安全性高，但是写的效率低，无论添加多少磁盘，都是n分之一的写速度，目前是两个100g的硬盘，加多一块100g的硬盘，整个磁盘组大小也是100g不变。

而ASM就跟我们的RAID1就类似了，在win或Linux环境下，配置RAID是需要成本的，要实现高可用的物理成本以及学习成本都是很高，但是Oracle提供了一种服务，ASM（自动磁盘管理）可以通过Oracle命令给我们完成高可用的磁盘阵列。

以上给大家简单的介绍了ASM组成，之前在学习搭建11gASM在网上查资料的时候，发现有位哥们写的文章是非常精细的，所以本章我就不细致介绍网格的搭建了，可以参考以下链接学习（11g
11.2.0.4 ASM+单实例静默安装）

Oracle ASM单实例静默安装+升级_总结、分享、交流-CSDN博客_oracle静默安装asm

说说我在安装ASM过程中遇到的一些问题吧：1. ASM磁盘建议不分区（使用裸盘）或者只分一个物理分区。（ASM磁盘无需挂载）2. 在对裸磁盘分区后，可能会遇到udev不识别磁盘的问题，建议重新挂载磁盘或更换规则绑定方式，如以上还是不能成功，建议使用裸设备作为ASM磁盘组。3. ASM磁盘组磁盘分区大小或者裸设备大小建议相同，例如目前有三块磁盘，建议都是同等大小，利于数据库识别以及写入。4. 在安装ASM磁盘建议能用RPM包的方式安装就使用，对linux udev熟悉的可以采用udev绑定，推荐优先使用udev，毕竟是服务器自带的工具，应对各场景下安装ASM。5. 对大于2T的磁盘分区要先用parted将分区转换为gpt格式，不然安装ASM无法识别磁盘。以上就是我在安装ASM过程中有遇到过的问题，我是在linux环境下静默安装的，如果各位还有遇到过别的问题，欢迎补充，大家一起解决商量。

/*
Oracle ASM 安装步骤
*/
–格式化磁盘，分区
大于2T以上的磁盘使用parted分区，小于则用fdisk，大于2T磁盘必须改为gpt分区

–udev规则绑定磁盘分区，规则文件位置，如果没有此文件则自行创建
/etc/udev/rules.d/99-oracle-asmdevices.rules

–查看磁盘uuid，通过uuid绑定udev规则指定（linux 6）
/sbin/scsi_id -g -u -d /dev/sdb
/*
这里我将三个磁盘进行分区，其中两块是固态盘，因为文件格式的关系，我分了6个分区，而剩余的机械盘同理文件格式问题，分了8个区，
以下为我的具体规则：
–KERNEL（分区名称/磁盘名称，可以用组显示sdb[1-5]，代表sdb1,sdb2…sdb5）
–SUBSYSTEM(设备的子系统名称，例如：sda 的子系统为 block。)
–PROGRAM（调用外部命令指定规则，可以通过父盘绑定也可以通过自身盘绑定）
–RESULT（uudi查询结果，PROGRAM 返回的结果。）
–NAME（别名，指定磁盘的别名，成功绑定后，原有被绑定的磁盘会以别名的形式出现在/dev目录下）
–OWNER（操作系统用户，ASM磁盘指定的用户）
–GROUP（操作系统组，ASM磁盘指定的分组）
–MODE（磁盘权限，默认0660）
/
–设置规则

–响应文件内容基本上按网格的环境变量内容写上即可，需要特别注意是为以下参数：
oracle.install.option=HA_CONFIG --这里因为我是为单实例数据库安装ASM，所以选择了HA_CONFIG，如果有别的需要集群可以选择CRS_CONFIG，视情况而定。
oracle.install.crs.config.storageOption=ASM_STORAGE --按照参数的提示，我们这里需要指定ASM_STORAGE的存储方式，而不是FILE_SYSTEM_STORAGE。
oracle.install.asm.diskGroup.name=SDATA --这里要注意的，上面我的磁盘组分成s和h开头的两个盘，s代表固态盘，h代表机械盘，
–为了ASM更好的管理（同类型、同大小的设备会产生更优越的性能），首先将两块固态
–盘作为第一个ASM磁盘组（SDATA），而机械盘可以等网格安装完后再添加上去，取名为
–HDATA。
oracle.install.asm.diskGroup.redundancy=EXTERNAL --这里有三个选项，是ASM的冗余等级，直接选择EXTERNAL最高等级冗余。
oracle.install.asm.diskGroup.AUSize=1 --视情况而定，这里是分配给ASM的使用单元，1为最小。

【删除ASM】
1.将grid用户环境变量下所有路径下的文件全部删除。
2.通过安装脚本查看ocr文件和olr文件的放置位置，并进行删除，一般会有两个路径：
OCR_LOC=/var/opt/oracle/ocr.loc
OCR_LOC=/etc/oracle/ocr.loc
3.再重新安装即可。
4.前提是还没创建磁盘组，只是单纯删除ASM软件。
5.dd if=/dev/zero of=/dev/asmdisks/asm-s1d6 bs=8192 count=128000 --清空ASM磁盘数据，用于重装ASM。

【安装过程遇到的问题】
1.安装ASM软件完成，但是磁盘组并没有按照响应文件的要求安装，可以手动使用以下命令安装（ O R A C L E H O M E / B I N ）： − 后面的是参数类型和对应的值，都是和响应文件里面匹配： − − 先绑定固态盘 . / a s m c a − s i l e n t − c o n f i g u r e A S M − d i s k S t r i n g ′ / d e v / a s m d i s k s / ∗ ′ − d i s k G r o u p N a m e S D A T A − d i s k L i s t / d e v / a s m d i s k s / a s m − s 0 d 1 , / d e v / a s m d i s k s / a s m − s 0 d 2 , / d e v / a s m d i s k s / a s m − s 0 d 3 , / d e v / a s m d i s k s / a s m − s 0 d 4 , / d e v / a s m d i s k s / a s m − s 0 d 5 , / d e v / a s m d i s k s / a s m − s 1 d 2 , / d e v / a s m d i s k s / a s m − s 1 d 3 , / d e v / a s m d i s k s / a s m − s 1 d 4 , / d e v / a s m d i s k s / a s m − s 1 d 5 , / d e v / a s m d i s k s / a s m − s 1 d 6 − r e d u n d a n c y E X T E R N A L − a u s i z e 1 − − 绑定机械盘 . / a s m c a − s i l e n t − c o n f i g u r e A S M − d i s k S t r i n g ′ / d e v / a s m d i s k s / ∗ ′ − d i s k G r o u p N a m e H D A T A − d i s k L i s t / d e v / a s m d i s k s / a s m − h 0 d 2 , / d e v / a s m d i s k s / a s m − h 0 d 3 , / d e v / a s m d i s k s / a s m − h 0 d 4 , / d e v / a s m d i s k s / a s m − h 0 d 5 , / d e v / a s m d i s k s / a s m − h 0 d 6 , / d e v / a s m d i s k s / a s m − h 0 d 7 , / d e v / a s m d i s k s / a s m − h 0 d 8 − r e d u n d a n c y E X T E R N A L − a u s i z e 12. 最后如果用集群检查命令没有出现以下磁盘（是否启动没关系），那就代表没安装成功 .
