我的Debian上有一个带有两个设备( )的镜像池。sda, sdb

现在我插入了两个额外的设备( sdc, sdd)，所以我可以将目录中的可用空间增加一倍。/mnt/data/

是由just完成的sudo zpool add backup-pool mirror sdc sdd吗？

我有点害怕，所以我想确认一下。对不起菜鸟问题。

以下是我的游泳池的详细信息：

我有这个小 bash 脚本：

readonly imagick_extension=$(cat "${php_configuration_file}" | grep imagick)
echo "Imagick extension grep value: $imagick_extension"
if [ "${imagick_extension}" != "extension=imagick.so" ]; then
        echo "ERROR: Imagick PHP extension is not enabled!"
        exit 1
fi
echo "Imagick PHP extension is enabled."

输出是：

Imagick extension grep value: extension=imagick.so
ERROR: Imagick PHP extension is not enabled!

这怎么可能？

  • 它说变量的值IS extension=imagick.so，

  • 但它仍然进入 if 子句，只有在它不存在的情况下才应该去 extension=imagick.so

提前致谢！
