Reason for Missing Disk Space in "df" Output
(Doc ID 2274696.1)
Last updated on MAY 12, 2020
Applies to:Linux OS - Version Oracle Linux 6.4 with Unbreakable Enterprise Kernel [2.6.32] and later
Oracle Cloud Infrastructure - Version N/A and later
Information in this document applies to any platform.
The total file system size does not matches with the used space and available space being reported in df output.
Ideally we assume that if we add Used column and Available column then it should give us the total size reported in 1K-blocks column and we can see from above output that it is not the case as sum
of used and available space comes to 617212408 which is 33025280 blocks less then total blocks.
