crs启动提示CRS-41053
crsctl start crs 启动数据库集群，遇到报错
[root@db02 ~]# crsctl start crsCRS-41053: checking Oracle Grid Infrastructureforfilepermission issues CRS-4124: Oracle High Availability Services startup failed. CRS-4000: Command Start failed, or completed with errors.权限不足？没做什么呀
用ai排查说是目录、文件权限的问题（开始误导），比较了节点1上的权限没什么不同。
检查alert.log

检查一下
[root@db02 ~]# df -hFilesystem Size Used Avail Use% Mounted on devtmpfs 32G032G0% /dev tmpfs 32G032G0% /dev/shm tmpfs 32G2.0G 30G7% /run tmpfs 32G032G0% /sys/fs/cgroup /dev/mapper/rhel-root 50G 50G 60K100% / /dev/vda1 1014M 171M 844M17% /boot /dev/mapper/vgora-lvora 200G 22G 179G11% /u01 /dev/mapper/rhel-home 46G8.1G 38G18% /home tmpfs6.3G06.3G0% /run/user/1101 tmpfs6.3G06.3G0% /run/user/0在/opt/oracle.ahf/orachk 目录下有个35G的orachk.zip 文件
清理后再启动crs
[root@db02 orachk]# crsctl start crsCRS-4123: Oracle High Availability Services has been started.节点2还是起不来crs。
重启主机后crs正常了（可能是有些临时文件在/tmp下没创建成功，重启后全部释放就自动恢复正常）。
问题又多了一个，为什么/tmp不单独创建？遇到这种根目录比较小的情况，容易出问题。
