However, neither could be assigned a mount point without requiring reformatting, implying data loss.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:
