rules ase avg 配置 sbin dwz wkt onf creat RHEL7下的udev管理與之前的版本有一定的區別，下面簡單介紹了基於LVM的UDEV配置。
1、創建邏輯卷
1、創建邏輯卷
[root@hdp06 ~]# pvcreate /dev/sdb [root@hdp06 ~]# vgcreate datavg /dev/sdb [root@hdp06 ~]# for id in catbs ustbs tmtbs;do lvcreate -n $id -L +512M datavg;done [root@hdp06 ~]# lvcreate -n tbs01 -L +20G datavg [root@hdp06 ~]# for id in stbs1 utbs1;do lvcreate -n $id -L +1G datavg;done [root@hdp06 ~]# ll /dev/dm-{2..7} brw-rw---- 1 root disk 249, 2 Jul 19 11:49 /dev/dm-2 brw-rw---- 1 root disk 249, 3 Jul 19 11:49 /dev/dm-3 brw-rw---- 1 root disk 249, 4 Jul 19 11:49 /dev/dm-4 brw-rw---- 1 root disk 249, 5 Jul 19 11:49 /dev/dm-5 brw-rw---- 1 root disk 249, 6 Jul 19 11:49 /dev/dm-6 brw-rw---- 1 root disk 249, 7 Jul 19 11:49 /dev/dm-7
2、獲取UUID
[root@hdp06 ~]# for i in {2..7};do udevadm info --query=all --name=/dev/dm-$i | grep -i DM_UUID;done E: DM_UUID=LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YfWXcy2QJ0N17L2HuAsEzTlfWBTMyXMjX E: DM_UUID=LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YIVnlrSdMdMe6MrdpzT1oWR4oGVYjLgTP E: DM_UUID=LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YA6DF2S7gHxiWwonFFnGskv8oqn09ehuJ E: DM_UUID=LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YX43yw6FLWfDYGKQ4iCMQYoj5CCaWsO0z E: DM_UUID=LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YV5Ft9f0ld7QjxASNgvkHFqoSWfgJqvsT E: DM_UUID=LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YJwktSMWrevmXvzi4DwzYvswwtOuu1U9o
對應的udev規則文件內容如下：
[root@hdp06 ~]# cat /etc/udev/rules.d/99-db2disk-owner.rules ACTION=="add|change", ENV{DM_UUID}=="LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YfWXcy2QJ0N17L2HuAsEzTlfWBTMyXMjX", NAME="catbs", OWNER="abcinst", GROUP="db2iadm", MODE="0660" ACTION=="add|change", ENV{DM_UUID}=="LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YIVnlrSdMdMe6MrdpzT1oWR4oGVYjLgTP", NAME="ustbs", OWNER="abcinst", GROUP="db2iadm", MODE="0660" ACTION=="add|change", ENV{DM_UUID}=="LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YA6DF2S7gHxiWwonFFnGskv8oqn09ehuJ", NAME="tmtbs", OWNER="abcinst", GROUP="db2iadm", MODE="0660" ACTION=="add|change", ENV{DM_UUID}=="LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YX43yw6FLWfDYGKQ4iCMQYoj5CCaWsO0z", NAME="tbs01", OWNER="abcinst", GROUP="db2iadm", MODE="0660" ACTION=="add|change", ENV{DM_UUID}=="LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YV5Ft9f0ld7QjxASNgvkHFqoSWfgJqvsT", NAME="stbs1", OWNER="abcinst", GROUP="db2iadm", MODE="0660" ACTION=="add|change", ENV{DM_UUID}=="LVM-F5TLuj05MSbaG40MlW1YJnvwLdGrZd7YJwktSMWrevmXvzi4DwzYvswwtOuu1U9o", NAME="utbs1", OWNER="abcinst", GROUP="db2iadm", MODE="0660"
3、啟動UDEV
[root@hdp06 ~]# /usr/sbin/udevadm trigger
[root@hdp06 ~]# ll /dev/dm-{2..7}
