Redhat5.5 cannot create logical partitions !!! -- Linux general technology-Linux technology and application information. For details, refer to the following section. The system/dev/sdc device partitions are as follows: Total size: 322.1 GB. An extended partition is created, and 14 other logical partitions are created. A total of 39162 cylinders are created before 5844 cylinders are used. There is still a lot of space, no more logical partitions can be

usually to use a symbolic link or a tool to adjust the partition size (such as PatitionMagic), but this is only a temporary solution, the problem is not fundamentally solved. With the appearance of the Logical Disk volume management function in Linux, these problems have been solved, and users can easily adjust the size of each partition without downtime.
