Root Filesystem Shows 100% Full
Applies To
Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64
Symptoms
The output from “df -h” command shows that the / filesystem is 100% full.
# df -h | egrep “Mounted|sda3” Filesystem Size Used Avail Use% Mounted on /dev/sda3 39G 39G 320M 100% /
Cause
In this case, the /u01 directory was not empty when the separate /u01 filesystem was mounted at /u01.
While what is currently displayed in /u01 is from the separate /u01 filesystem, the files present in /u01 on the root filesystem before the mount of /u01 are still there and taking up space in the root filesystem.
