difference between output of df and blkid
Clash Royale CLAN TAG#URR8PPP
When I run blkid I get
/dev/vda1 ...etc
/dev/vda2 ...etc
However, when I run df -h I do not see the second drive. I only see
/dev/vda1 ...etc
/devtmpfs ...etc
Is this because df only shows file systems that are mounted, and the vda2 drive is not mounted? Can you help me understand the difference between the two and why df -h doesnt show the second drive vda2 ?

forgive me for a dumb question but, are you saying that, or the man page is insinuating that, since the drive is not mounted it has no name?

what is the prefered, or easiest method to list either all file systems, or something to show filesystems that are not mounted?

1.dfshows only mounted file systems; 2. Different tools are 'best' for different purposes, maybe you will findlsblkbest for this particular purpose (to list all file systems and show if they are mounted). It will show all drives and partitions, not only those with file systems, but also a swap partition, an extended partition, and a partition that is not yet formatted.

From the relevant man pages:
"blkid - locate/print block device attributes"
"df - report file system disk space usage"
So df tells you about disk space usage of the filesystems on those block devices.
In response to your supplementary comments on your question, it's not that either is "best" per se, they are different tools.
