As a system administrator, we often encounter the need to increase or shrink a file system. For the mainstream OS and Linux on UNIX, dynamic Logical Volume management (LVM) is a great help for us to do this job. But for Solaris systems that do not support LVM, they can only be implemented in a stupid way. Assuming a w

After the device is switched OFF and restarted, most of them will be automatically ruled out.Most real problems need to be solved by the vendor. That is to say, the key to getting started is to master the host system that accounts for 1/5 of the total, so that you can easily deal with them.Of course, you may make some configuration changes on
