Unmount the flie system, and then mount it with the additional mount option "init_itable=0". From Documentation/filesystems/ext4.txt: init_itable=n The lazy itable init code will wait n times the number of milliseconds it took to zero out the previous block group's inode table. This minimizes the impact on the system performance while file system's inode table is being initialized. Hope this helps, - Ted
