A: When the multiple partitions are mounted to the same directory, the directory will only display the content of the final mounting partition. After uninstalling the final mounting partition, the directory will display the penultimately mounted partition.
5) What should I do if the disk space is insufficient
A: When the application reports that "disk space is insufficient", it is usually first that ordinary users do not have space creation or expansion files, which may cause users to be unable to log in. However, generally speaking, the system administrator can still log in to perform some management operations, such as deleting some temporary files, such as the/TMP directory, some content in the/var/log directory, restore some disk space. If you need to increase the space, you can consider the expansion of the partition. One way is to create a new partition (a new hard disk may be required), and then the partition is mounted to a directory with a relatively large space, such as/opt,/home, and transferring the content in the original directory In the new district, then modify the/ETC/FSTAB so that the default of the partition is mounted to the specified directory. Another method requires the partition of insufficient space in LVM (logic volume) format. At this time, you can use PVCREATE to create a new LVM physical volume, use the logical volume of lack of LVEXTEND expansion space, and then expand the partition with Resize2FS (need to uninstall the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, the partition, If it is/partition, you need to operate under RescueShell), please refer to the LVM related manual for related commands. It is recommended to use it with caution.
