Linux R720挂载M.2固态硬盘

因为预算问题，没法买服务器级别的PCIE固态，于是在某东买了一块

M.2固态硬盘 和 一个 M.2转PCIE的卡。

顺便重温下Linux挂载硬盘

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0x78189e91.

Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to

switch off the mode (command 'c') and change display units to

sectors (command 'u').
