Ah, sorry. I didn't understand what problem you were trying to solve. But mke2fs does accept the filesystem size accounted in kilobytes (and megabytes, gigabytes, etc.). So you could just take the size in bytes, divide by 1024, and then append 'k', i.e: mke2fs $MKFS_OPTS $DEVICE $(expr $bytes / 1024)k This will work regardless of the block size.
