Oracle VM: I-node Usage Is At 100% (Doc ID 2162663.1)

Last updated on JULY 29, 2016

Applies to:

Oracle VM - Version 3.2.7 to 3.4.1 [Release OVM32 to OVM34]
Information in this document applies to any platform.

Symptoms

Attempts to create new files fail.  This is disruptive for the VM guest.  Error messages indicate that I-node usage is at the 100% level.

Most file metadata, such as its size and access permissions, are stored in a I-node instead of with the file itself.  Each file is assigned an I-node when the file is created.  When all I-nodes have been consumed, no new files can be created until an I-node is released by deleting a file.

N.B.  Nobody is quite sure what the term I-node really means. Conjecture offers index-node or information-node, but when the original tree-structured filesystem was designed the meaning was so obvious that the definition was not written down.
