Solved: A specific user is not able to see usage statistics in “df” command output ?

In this post, we will look at a small and interesting issue where when we do “df” to see the filesystem usage, we are not able to see the details from a specific user.

Lets see the actual issue below.

/dev/mapbprdlg1lv         -         -    -        -      - /mapbprd/db/archredo1

/dev/mapbprdlg2lv         -         -    -        -      - /mapbprd/db/archredo2

 

Solution

The solution is pretty easy, the user Mike don't have permission to go into these partitions/directories.

Hence we need to Check permissions of /mapbprd and /mapbprd/db and correct them so that a particular user can have read and execute permissions to read that mount point.
