Hi Guys, Thanks for your time to look into this While connecting a block volume to my instance I m getting the below error Command: mkfs.ext4 /dev/sdd1 Error Message: mke2fs 1.42.9 (28-Dec-2013) Could not stat /dev/sdd1 --- No such file or directory The device apparently does not exist; did you specify it correctly? Before executing this command I did run iscsi command to attach followed by these partition commands, all completed successfully parted -s -a optimal /dev/sdd mklabel gpt parted -s -a optimal /dev/sdd mkpart primary '1MiB -1' Any idea? Thanks, Alok
