How to resize an EXT3 if default block size is changed to 1K from 4K
Solution 1:
Using mkfs command to change block site and also other utility to change the block site which below: 1) gpart 2) parted
Other option:
root@space:~# mkfs.ext4 –m 0 -b 4096 /dev/rootfs
Solution 2:
Given 2 TB of 1K blocks is right at the 2 billion mark, you probably are over the maximum blocks of ext3.
Note that Red Hat suggest 4K block sizes to achieve the max 16TB
