Write To Ocfs2 Volume gets No Space Error Despite Large Free Space Available
Last updated on JANUARY 04, 2016
Applies to:Linux OS - Version Oracle Linux 5.5 and later
When attempting to create or extend a file in an ocfs2 volume, an error is returned. The "df " command shows the ocfs2 volume has more than sufficient free space to create or extend a file, but attempts to do so get error:
The symptoms can vary depending upon the utility in use.
An example from "rman":
ORA-19502: write error on file "/oradata/data_09.dbf", blockno 192673 (blocksize=8192)
ORA-27072: File I/O error
Linux Error: 5: Input/output error
Another example was where an Oracle VM guest was allocated a sparse file in an ocfs2 repository to use for a swap file - the guest encountered a write error when ocfs2 was unable to extend the file:
kernel: loop: out of space on target file
The problem is usually triggered after an extended period where many files are created and deleted.
