Recently, the computer room reported an alarm problem on the hard disk of a server. The orange light is always on. Hot-plugging in the computer room is still the same, and the file is read-only and cannot be written. It is estimated that the installation of zabbix monitoring in the project increases the I/O pressure on the hard disk, causing problems with the hard disk.
