Increase or Decrease the Size of Static Partition in Linux

There are two Memory Management Techniques: Contiguous, and Non-Contiguous. In Contiguous Technique, the executing process must be loaded entirely in the main memory. Contiguous Techniques can be divided into:

1. Fixed (or static) partitioning
2. Variable (or dynamic) partitioning

• So first we have created a fixed partition in sdb hard disk of size 5G and mounted it to the /ld mount point.

• Now we would unmount sdb1 partition from the folder and reun e2fsck command. The e2fsck command is used to check the ext2/ext3/ext4 family of file systems. For ext3 and ext4 filesystems that use a journal, if the system has been shut down uncleanly without any errors, normally, after replaying the committed transactions in the journal, the file system should be marked as clean.
• Then we would delete the 5G partition.

• After deleting the 5G partition, we would create a new partition of the new required size(in this case, 7G). In the process of deleting the file, we would not delete the ext4 signature in the partition.

• Now we have created a new partition of 7G, and now we have to mount it.

• First we would run resize2fs command to format it in a special way such that no data is lost. Then we would mount it to the desired folder.
