简述：
-在xx项目中遇到DSC迁移需求，原来环境是arm+Kylin，要迁移到arm+uos环境,记录一下绑定磁盘过程中遇到的问题

1、uos系统版本

root@czt-PC:/etc# cat /etc/os-version
[Version]
SystemName=UnionTech OS Server
SystemName[zh_CN]=统信服务器操作系统
ProductType=Server
ProductType[zh_CN]=服务器
EditionName=d
EditionName[zh_CN]=d
MajorVersion=20
MinorVersion=1050
OsBuild=12014.101
root@czt-PC: cat /etc/debian_version
10.10

2、共享磁盘

root@czt-PC:/etc# lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sr0     11:0    1 1024M  0 rom
vda    253:0    0  600G  0 disk
├─vda1 253:1    0  300M  0 part /boot/efi
├─vda2 253:2    0  512M  0 part /boot
├─vda3 253:3    0   20G  0 part /
├─vda4 253:4    0 52.2G  0 part /deepin/userdata
├─vda5 253:5    0   21G  0 part /recovery
└─vda6 253:6    0    6G  0 part [SWAP]
vdb    253:16   0  1.5T  0 disk
vdc    253:32   0   10G  0 disk
vdd    253:48   0    5G  0 disk
vde    253:64   0    5G  0 disk
vdf    253:80   0  100G  0 disk

通过uuid.sh绑定磁盘发现没有生效
查看发现是纯虚拟盘无法获取id，打算采用裸设备的方式进行绑定

root@czt-PC:/home/czt# ls -al /dev/disk/by-id
total 0
drwxr-xr-x 2 root root 320 Jul  4 11:20 .

lrwxrwxrwx 1 root root   9 Jul  4 02:21 virtio-fa32b966-f989-4761-a -> ../../vdd

3、绑定裸设备

root@czt-PC:/etc# cat /etc/udev/rules.d/60-raw.rules
ACTION=="add", KERNEL=="vdb", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="vdc", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="vdd", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="vde", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="vdf", RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="raw[1-5]", OWNER="dmdba", GROUP="dinstall", MODE="660"

直接重启服务器发现同样没有生效!
通过排查发现是raw模块没有加载导致的

root@czt-PC:~# raw -qa
raw: Cannot open master raw device '/dev/raw/rawctl': No such file or directory
root@czt-PC:~# zgrep -i raw /proc/config.gz
CONFIG_INET_RAW_DIAG=m
CONFIG_IP_NF_RAW=m
CONFIG_IP6_NF_RAW=m
CONFIG_CAN_RAW=m
CONFIG_ARCNET_RAW=m
CONFIG_HDLC_RAW=m
CONFIG_HDLC_RAW_ETH=m
CONFIG_SERIO_RAW=m
CONFIG_RAW_DRIVER=m
CONFIG_MAX_RAW_DEVS=4096
# CONFIG_IR_IMON_RAW is not set
CONFIG_HIDRAW=y
CONFIG_HID_UDRAW_PS3=m
CONFIG_USB_SERIAL_SIERRAWIRELESS=m
#加载模块
root@czt-PC:~# modprobe raw
root@czt-PC:~# raw -qa
root@czt-PC:~# ls -al /dev/raw/
total 0
drwxr-xr-x  2 root root     60 Jul  1 05:17 .
drwxr-xr-x 20 root root   4540 Jul  1 05:17 ..
crw-rw----  1 root disk 162, 0 Jul  1 05:17 rawctl
##模块开机自动加载
root@czt-PC:/etc/modules-load.d# pwd
/etc/modules-load.d
root@czt-PC:/etc/modules-load.d# cat raw.conf
raw

再次重启服务器发现还是没有生效，检查模块加载正常，最后发现是由于raw命令目录不正确导致无法正常绑定

root@czt-PC:/bin# pwd
/bin
root@czt-PC:/bin# ./ra
ranlib     rasttopnm  rawtopgm   rawtoppm
root@czt-PC:/bin# whereis raw
raw: /usr/sbin/raw /usr/share/man/man8/raw.8.gz

重新修改配置文件

root@czt-PC:/bin# cat /etc/udev/rules.d/60-raw.rules
ACTION=="add", KERNEL=="vdb", RUN+="/usr/sbin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="vdc", RUN+="/usr/sbin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="vdd", RUN+="/usr/sbin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="vde", RUN+="/usr/sbin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="vdf", RUN+="/usr/sbin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="raw[1-5]", OWNER="dmdba", GROUP="dinstall", MODE="660"

重启服务器验证是否生效

root@czt-PC:/bin# ls -al /dev/raw/*
crw-rw---- 1 dmdba dinstall 162, 1 Jul  1 05:44 /dev/raw/raw1
crw-rw---- 1 dmdba dinstall 162, 2 Jul  1 05:44 /dev/raw/raw2
crw-rw---- 1 dmdba dinstall 162, 3 Jul  1 05:44 /dev/raw/raw3
crw-rw---- 1 dmdba dinstall 162, 4 Jul  1 05:44 /dev/raw/raw4
crw-rw---- 1 dmdba dinstall 162, 5 Jul  1 05:44 /dev/raw/raw5
crw-rw---- 1 root  disk     162, 0 Jul  1 05:44 /dev/raw/rawctl

配置开启自启动文件

root@czt-PC: vim /etc/rc.loca
root@czt-PC: chmod +x /etc/rc.loca
root@czt-PC:/bin# cat /etc/rc.local
chown -R dmdba:dinstall /dev/raw/*
