PrefaceAPP Scenario Description:When you are unable to plan your storage properly, the storage re-planning (eg, one or several apps that write bigdata for a certain LV-mount point in a post-maintenance job may soon be out of space for your LV mount point, but it's worth noting that Does your other LV mount point have a large storage space? Basically not applied to this LV mount point to write data?) According to the previous description, we know that the problem solution we might be able to choo

Can the ipad Pro be plugged into an expansion card? The ipad Pro can not plug an expansion card. The ipad Pro thickness is 6.9 mm, 0.8 millimeters thicker than last year's ipad Air 2, and weighs more heavily than the ipad Air 2, which feels slightly bulky. But the ipad Pro's size and storage capacity have increased. The ipad Pro offers 10-hour endurance, and the display area is nearly 10% larger than other

PHP Dynamic Expansion Module installation所谓动态模块，就是一个独立存在的.so文件。php一旦编译完成后，想要再增加一个模块的话要么重新编译php，要么直接编译一个扩展模块，（生成一个.so文件），然后在php.ini中配置一下，就可以被加载使用了。这里我们用redis来做实验。First we go into the cd/usr/local/src/directory.First we want to see which modules are loaded in PHP/USR/LOCAL/PHP/BIN/PHP-M//View moduleWe found that there was no Redis module, and then we went to download a module.wget Https://codeload.github.com/phpredis/phpredis/zip/developThen rename the

But if your initial capacity is too large and the data is growing slowly, it is wasting memory.How to choose, or to see the specific application of the scene.(2), HashMap capacity growth modeHashMap mainly use arrays to store data, we all know that it will hash the key, the HA operation will

Kotlin Extension Kotlin can extend the properties and methods of a class and do not need to inherit.An extension is a static behavior that does not have any effect on the extended class code itself.

Previously built a CentOS (7.0, x64) VM, has not been aware of its hard disk space. Yesterday, the system suddenly pop-up warning, said the root directory space is insufficient.In this case, you can only add space to it. I've actually increased my hard disk space, but to write this blog, I've added 10GB hard drives again. On the premise of the virtual machine shutdown , first, through VMware to the virtual machine to add some hard disk space, the following figure:After clicking "Expand", wait a
