How was the ext4 filesystem created and what was its block size ?
You can see the block size with blkid or tune2fs -l.
The Ext4 filesystem on /dev/sda5 was created using mkfs.ext4 -T
largefile4 /dev/sda5.
Its block size is 64KB.
To clarify how the Ext4 filesystem on /dev/sda5 was created and its
block size, here is the command output used:
"root@debian:/home/usr# /sbin/mkfs.ext4 -T largefile4 /dev/sda5
mke2fs 1.47.0 (5-Feb-2023)
Creating filesystem with 491520 64k blocks and 8192 inodes

Thanks Trupti.
