Docker 基础9
可见 docker.service 是依赖于 docker.socket 的，但是并不必要开启 Tip: 其实上面的步骤完成，就已经能保证docker会开机启动，原因是它依赖的 docker.socket 虽然本身设定为不要开机启动，但开机时会被systemctl检查然后触发启动以支持 docker.service 的运行 可以用上面方法也将 docker.socket 设为开机启动(但这一步不是非常必要 ) [root@h103 ~]# systemctl list-unit-files| grep docker docker.service enabled docker.socket disabled [root@h103 ~]# systemctl enable docker.socket /docker.socket.

Default: 'posix'. fadvise_hint=bool By default, fio will use fadvise() to advise the kernel on what IO patterns it is likely to issue. Sometimes you want to test specific IO patterns without telling the kernel about it, in which case you can disable this option. If set, fio will use POSIX_FADV_SEQUENTIAL for sequential IO and POSIX_FADV_RANDOM for random IO. fadvise_stream=int Notify the kernel what write stream ID to place these writes under. Only supported on Linux. Note, this option may change going forward. size=int The total size of file io for this job. Fio will run until this many bytes has been transferred, unless runtime is limited by other options (such as 'runtime', for instance, or increased/decreased by 'io_size'). Unless specific nrfiles and filesize options are given, fio will divide this size between the available files specified by the job. If not set, fio will use the full size of the given files or devices. If the files do not exist, size must be given. It is also possible to give size as a percentage between 1 and 100. If size=20% is given, fio will use 20% of the full size of the given files or devices. io_size=int io_limit=int Normally fio operates within the region set by 'size', which means that the 'size' option sets both the region and size of IO to
