How to get a newly created EXT4 filesystem to finish writing the index node immediatly?

cn flag

I newly created an ext4 1TB partition, but I could not spin down the Hard disk on which the partition is mounted without unmounting first because the disk is having some activity every about 2s. I did some searching on the internet and found about the ext4lazyinit which is slowly creating the "index node" on the partition. Can I force it to create the node immediately instead of gradually over a long time?

According to the hard disk activity tool, the hard disk is writing 4 MiB at regular intervals.

I found the solution: unmount the filesystem and remount it temporally adding -o init_itable=0 to force ext4lazyinit to work faster on completing its job.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
