SSH to your VM and check if the volume is present (/dev/vdb) with ls
Use mkfs.ext4 (or another mkfs.* command) to format the POSIX filesystem on the volume:
sudo mkfs.ext4 /dev/vdb
Remember to use sudo for these commands!
The filesystem is ready, but still needs to be mounted.
Create a mountpoint with mkdir -p, then mount the filesystem to the mountpoint:
sudo mkdir -p /mnt/workspace
sudo mount /dev/vdb /mnt/workspace
Check the status with df -h
Notice that filesystems lose some capacity due to formatting. We’ll teach you how to adjust the volume size later
You’re almost ready to use the new workspace!
Final detail: the mounted filesystem is read-only for regular users. If you want to avoid sudo on every command, open the permissions with chmod:
chmod 777 /mnt/workspace
