Description

Without specifing "-b block-size" mke2fs creates journal_dev with "Block size 1024" on "Journal size: 21M" device and llmount.sh fails to create Lustre with external journal:

   mke2fs: Filesystem has unexpected block size while trying
           to open journal device /dev/vdb

because the target device itself is created with default "Block size: 4096".
