How to run FSCK with write capabilities on a sever with 4+ partitions

Question

I wanted to know how to run the fsck command on a server with write capabilities. The command should run structurally from one hard disk partition to another without any user interaction.

Answer 1

It depends on the type of filesystem you are using. Ext2/3/4, for example, cannot safely run on a mounted filesystem, so you must either boot into single user mode, or use a boot disk. Other types allow mounted checks in writemode (btrfs, etc.).
