The second to last argument is in relation with the dump command normally set at 1 for real filesystems, 0 for swap and NFS mounted filesystems. Note. 2 A best practice is to execute the mount a command, each time you change something in the etcfstab file to detect any boot problem before it occurs.

However, although the creation time is now very quick, a process in the background continues to work for several minutes according to the size of the filesystem This process called ext. Although definitively not required for the RHCSA exam, you can create an ext. E lazyitableinit0,lazyjournalinit0 devvglvvol. Source Red Hat. Additional Resources.
