14.11. 在使用加密磁盘的系统中运行 kdump

流程

1. 输出估计的 crashkernel= 值：

   # *kdumpctl estimate*
   
   Encrypted kdump target requires extra memory, assuming using the keyslot with minimum memory requirement
      Reserved crashkernel:    256M
      Recommended crashkernel: 652M
   
      Kernel image size:   47M
      Kernel modules size: 8M
      Initramfs size:      20M
      Runtime reservation: 64M
      LUKS required size:  512M
      Large modules: <none>
      WARNING: Current crashkernel size is lower than recommended size 652M.

2. 通过增加 crashkernel= 值来配置所需的内存量。
3. 重启系统。
