I'm having a simple trouble updating my block storage using resize2fs. The error message sounds quite simple and straight forward, but I have no clue to solve this problem.

$ resize2fs /dev/vdb
resize2fs 1.45.5 (07-Jan-2020)
open: No such file or directory while opening /dev/vdb
Thanks for your help in advance!
The error ”No such file or directory while opening /dev/vdb” means ‘dev/vdb’ does not exist. So check the current availability of the block device in the system by using below command fdisk-1. (fdisk tries to update the kernel after it has written the partition table. However this will fail if the disk is in use). You can also run the lsblk command to check which partition needs to be extended.
Make sure you have proper permissions to manage block devices check by using below command
sudo growpart /dev/vdb
sudo resize2fs /dev/vdb.
Run df -h now it shows more available space and refer to this document also.
